FIELD OF TECHNIQUE
[002] The invention relates generally to a new and improved electric motor/generator and, in particular, to an improved system and method for producing rotary motion from an electromagnetic motor or generating electrical power from a rotary motion input. BACKGROUND INFORMATION
[003] Electric motors use electrical energy to produce mechanical energy, most typically through the interaction of magnetic fields and current-carrying conductors. The conversion of electrical energy into mechanical energy by electromagnetic means was first demonstrated by British scientist Michael Faraday in 1821 and later quantified through the work of Hendrik Lorentz.
[004] A magnetic field is generated when electrical charge carriers such as electrons move through space or within an electrical conductor. The geometric shapes of the lines of magnetic flux produced by moving charge carriers (electric current) are similar to the shapes of the lines of flux in an electrostatic field. Magnetic flux passes through most metals with little or no effect, with certain exceptions notably iron and nickel. These two metals, and alloys and mixtures that contain them, are known as ferromagnetic materials as they concentrate magnetic lines of flux. Areas of greater field strength or flux concentration are known as magnetic poles.
[005] In a traditional electric motor, a central core of tightly packed current-carrying material creates magnetic poles (known as the rotor) that rotate or rotate at high speed between the fixed poles of a magnet (known as the stator) when an electric current is applied. The central core is typically coupled to a shaft that will also rotate with the rotor. The shaft can be used to drive gears and wheels on a rotating machine and/or convert rotational motion into a straight line.
[006] Generators are usually based on the principle of electromagnetic induction, which was discovered by Michael Faraday in 1831. Faraday discovered that when an electrically conducting material (such as copper) is moved through a magnetic field (or vice versa), an electric current will begin to flow through that material. This electromagnetic effect induces electrical voltage or current to the moving conductors.
[007] Current Generating Devices Power devices such as rotary alternator/generators and linear alternators rely on Faraday's discovery to produce power. In fact, rotating generators are essentially very large amounts of wires rotating around the interior of very large magnets. In this situation, the coils of wire are called armature as they are moving relative to the stationary magnets (which are called stators). Typically, the moving component is called armature and stationary components are called stator or stators.
[008] Currently used motors and generators produce or use a time-varying sinusoidal voltage. This waveform is inherent to the operation of these devices.
[009] In most conventional motors, both linear and rotary, a sufficient power of the proper polarity needs to be pulsed at the right moment to supply an opposing (or attracting) force on each pole segment to produce a particular torque. In conventional motors, at any given time only a portion of the coil pole parts is actively supplying torque.
[010] With conventional motors a pulsed electrical current of sufficient magnitude needs to be applied to produce a certain torque/horsepower. Horsepower output and efficiency is then a function of design, electrical input power plus losses.
[011] With conventional generators, an electrical current is produced when the rotor is rotated. Power generated is a function of flux resistance, conductor size, number of pole pieces and speed in RPM. However, the output is a sinusoidal output with the same losses as shown in conventional electric motors.
[012] A conventional linear motor/generator, on the other hand, can be visualized as a typical electric motor/generator that has been cut open and unpacked. The "stator" is configured in the form of a rail of flat coils produced from aluminum or copper and is known as the "primary" of a linear motor. The "rotor" takes the form of a mobile platform known as the "secondary". When the current is turned on, the secondary slides past the primary supported and driven by a magnetic field. A linear generator works the same way, but mechanical power provides the force to move the rotor or secondary after magnetic fields.
[013] In traditional generators and motors, pulsed magnetic fields that vary with time produce unwanted effects and losses, that is, Iron Hysteresis losses, Inverse Electromotive Force, inductor return, eddy currents, inrush currents, torque ripple , heat losses, grinding, brush losses, high wear in brushed designs, switching losses, and magnetic vibration of permanent magnets. In many cases, complex controllers are used in place of mechanical switching to handle some of these effects.
[014] In motors and generators that use permanent magnets it is desirable to increase the magnetic flux densities to achieve a more efficient operation. Most of the permanent magnet motors/generators used today rely on permanent magnets such as Neodymium magnets. These magnets are the strongest of the magnetic materials produced by humans. Due to their strategic value to industry, and their high costs, it is desirable to increase flux densities without relying on an innovation in material composition of these magnets or the fabrication of high density special purpose magnet sizes and shapes.
[015] In motors or generators, some form of energy drives the rotation and/or movement of the rotor. As energy becomes more scarce and costly, more efficient motors and generators are needed to reduce energy costs. SUMMARY
[016] In response to these and other problems, several modalities disclosed in this application are presented, which include methods and systems to increase the flux density through permanent magnet manipulation. Specifically, methods and systems for increasing flux density that utilize commercially available sizes and shapes that can be chosen based on lowest cost rather than based on flux density. Methods of producing mechanical power are also described by moving a coil/s coupled to a core into a magnet assembly with an increased flux density or producing an electrical output power when the coils are mechanically forced through the magnetic assembly with an increased flux density. In certain aspects, within the magnetic cylinder or magnet assembly, lines of magnetic flux are created and augmented through the configuration of permanent magnets or electromagnets and are confined within the magnetic cylinder or magnet assembly until they exit at predetermined locations.

There are no pole pieces to provide repulsion or magnetic attraction that produce current output more efficiently than traditional generators.

[078] Specific examples of components, signals, messages, protocols and arrangements are described below to simplify the present disclosure. Of course, these are merely examples, and are not intended to limit the invention to what is described in the claims. Well-known elements are presented without a detailed description so as not to complicate the present invention with unnecessary detail. For the most part, details unnecessary to gain a full understanding of the present invention have been omitted as such details fall within the skills of individuals of ordinary skill in the relevant art. Details relating to a set of control circuits, power supplies, or a set of circuits used to power certain components or elements described in this document are omitted, as such details are within the skill of individuals of ordinary skill in the relevant art.
[079] When directions such as top, bottom, top, bottom, clockwise or counterclockwise are discussed in this disclosure, such directions are intended to provide only reference directions for the illustrated Figures and for the orientation of components in the Figures . Directions should not be read as representing actual directions used in any invention or resulting actual use. Under no circumstances should such directions be read as limiting or conveying any meaning to the claims.
[080] Most motors and generators in use today require or produce a time-varying sinusoidal voltage called Alternating Current (AC). When direct current is used it is necessary to first reverse and pulse it to replicate an AC waveform to produce the desired current or mechanical output. Certain embodiments of the present invention do not produce or utilize an Alternating Current, but instead directly produce or utilize a non-sinusoidal Direct Current without the need for rectification or switching. This results in the elimination of Alternating Current Losses and results in a more efficient use of input or output power. However, certain aspects of the invention can accept any rectified A/D current and thus can be "blind" to phasing input power supply. Thus, single-phase rectified single-phase, two-phase, three-phase, etc. are acceptable for input power depending on configuration.
[081] Turning now to Figure 1, there is a cross-sectional view of an embodiment of a toroidal magnetic cylinder 100 illustrating representative plane magnetic flux paths 101 within and around the cylinder. These are representative illustrations; Actual flow paths depend on material design and the specific configuration of magnets within the cylinder. Magnetic cylinder 100 comprises an outer cylinder wall 102 and an inner cylinder wall 104. Outer cylinder wall 102 and inner cylinder wall 104 can be produced with a plurality of magnets. In a side sectional view, as illustrated in Figure 1, it can be seen that the outer cylinder wall 102 is made up of a plurality of magnets 106, comprising individual magnets, such as magnets 106a, 106b, 106c, etc. Similarly, the inner cylinder wall 104 may be comprised of a plurality of magnets 108, comprising individual magnets 108a, 108b, etc. It should be noted that only one polarity of the magnets is used within (or facing towards) the magnetic cylinder or magnet assembly.
[082] In certain embodiments, there may be a central iron core 110 positioned between the outer wall 102 and the inner wall 104, however other core materials may be used when design considerations such as strength, eddy current reduction, channel cooling, etc. are considered.
[083] In certain embodiments, the plurality of magnets 106 and magnets 108 can be produced from any suitable magnetic material, such as: neodymium, Alnico alloys, ceramic permanent magnets or electromagnets. In certain embodiments, each magnet 106a or 108a in the respective plurality of magnets has dimensions of 2.54 cm x 2.54 cm x 2.54 cm (1" x 1" x 1") The exact number of magnets or electromagnets will depend magnetic field strength or mechanical configuration required. The illustrated modality is just one way of arranging the magnets, based on certain commercially available magnets. Other arrangements are possible - especially if the magnets are manufactured for this specific purpose.
[084] When the plurality of magnets 106 and 108 are disposed within outer wall 102 and inner wall 104 to form cylinder 100, the flow lines 101 will form particular patterns as conceptually restated by the flow lines illustrated in Figure 1. The actual shape, direction and orientation of the flow lines 101 depend on factors such as the use of an internal containment ring, configuration and material composition. For example, the flow line 112a from magnet 106a on the outer wall tends to flow from the north pole of the magnet in a perpendicular manner from the face of the magnet around cylinder 100, and back through an open end. 114, then flows through the iron core 110 and back to the face of the magnet 106a that contains the south pole. Similarly, the flow line 112b from magnet 106b on outer wall 102 tends to flow from the north pole of the magnet in a perpendicular manner from the face of the magnet around cylinder 100, and back through the open end 114 , then flow through the iron core 110 and back to the face of magnet 106b that contains the south pole. Although only a few lines of flow 112 are illustrated for clarity, each successive magnet in the plurality of magnets will produce similar lines of flow. Thus, the magnetic flux forces for each successive magnet in the plurality of magnets 106 tend to follow these flux lines or illustrative patterns 112 for each successive magnetic disk in the plurality of magnets 106 until the magnets at the open ends 114 or 116 of the magnetic cylinder 100 are reached.
[085] Magnets on the opposite side of cylinder 100, such as magnet 106c, tend to generate flow lines 112c from magnet 106c on outer wall 102 which tends to flow from the north pole of the magnet in a manner perpendicular to from the face of the magnet around the cylinder 100, and back through an opposite open end 116, then flows through the iron core 110 and back to the face of the magnet 106c which contains the south pole. Although only a few lines of flow 112 on the opposite side of cylinder 100 are illustrated for clarity, each successive magnet in the plurality of magnets will produce similar lines of flow.
[086] In certain embodiments, the inner wall 104 still produces flow lines 118. For example, the flow line 118a from the magnet 108a on the inner wall 104 tends to flow from the north pole in a manner perpendicular to from the face of the magnet, around the inner wall 104 through the iron core 110, and back through the radial center of the inner wall 104 to the face of the magnet 108a which contains the south pole. Similarly, flow line 118b from magnet 108b in inner wall 104 tends to flow from the north pole in a perpendicular manner from the face of the magnet, around inner wall 104 through iron core 110, and from back through the radial center of inner wall 104, then back to the face of magnet 108b that contains the south pole.
[087] The magnetic flux forces for each successive magnet in the plurality of magnets 108 tend to follow these flux lines or illustrative patterns 118 for each successive magnet in the plurality of magnets 108 until the open ends 114 or 116 of the magnetic cylinder 100 are achieved. Thus, the flux produced by the magnets of the inner wall 104 of the cylinder 100 has an unobstructed path to exit through the center of the cylinder and return to the opposite pole outside the cylinder.
[088] In some embodiments, the magnetic flux lines 112 and 118 will tend to develop a stacking effect and the outer magnetic cylinder configuration manipulates the flux lines 101 of the magnets in the magnetic cylinder 100 so that most or all of the flow lines 110 flow out of the open end 114 and 116 of cylinder 100.
[089] In conventional configurations, the opposite poles of the magnets are normally aligned longitudinally. Thus, the field flux lines will "embrace" closely followed the surface of the magnets. Thus, during the use of conventional power generation/utilization equipment, the clearances normally need to be extremely tight in order to have the ability to act on these power lines. By aligning similar magnetic poles radially with respect to the center 120 of cylinder 100, lines of magnetic flux 112 and 118 tend to pile up as they pass through the center of magnetic cylinder 110 and are radiated perpendicularly from the surface of the magnets. This configuration allows for greater tolerances between the coils and the magnetic cylinder 100.
[090] In certain embodiments, the iron core 110 is positioned concentrically around the center 120 of the magnetic cylinder 100 so that the iron core is radially equidistant from the inner wall 104, generating a representative flow pattern 101 as illustrated in Figure 1. The lines or fields of flow are attracted to the iron core 110 and compressed as they approach the iron core. The flux fields can then establish what can be visualized as a series of "flux walls" that surround the iron core that extends along the cylinder and exit points.
[091] Turning now to Figure 2a, a conceptual isometric view of the toroidal magnetic cylinder 100 is presented that has the central iron core 110 positioned inside the magnetic cylinder. Figure 2b is a partial detailed view of the toroidal magnetic cylinder 100 illustrating the flux walls or plane magnetic fields 122 generated within the internal cavity 124 of the magnetic cylinder 100 in conjunction with the iron core 110. These are representative illustrations; actual flow walls 122 are configuration and material design dependent.
[092] The cylinder 100 as shown in Figures 1, 2a and 2b was conceptualized to illustrate the basic flow lines or trajectories of a partial magnetic cylinder with an iron core located concentrically in a hollow portion of its walls. From a practical perspective, a core or rotor assembly can position core 110 within magnetic cylinder 100.
[093] Turning now to Figure 3, an isometric view is presented of an embodiment of an assembly 130 comprising an iron core 132, a rotor hub 134 and shaft 136. The iron core 132 is similar to the core 110 discussed above. Iron core 132 and rotor hub 134 are secured to a shaft 136 using conventional fastening methods known in the art. In certain embodiments, the rotor hub 134 can be composed of non-ferrous materials, for example, to eliminate the production of eddy currents. When mounted with the magnetic cylinder 100, a transverse slot 162 (not shown in Figure 3) in the inner wall 104 of the magnetic cylinder (not shown in Figure 3) allows the core 132 and a portion of the rotor hub 134 to extend through the inner wall 104 of magnetic cylinder 100 and into inner cavity 124 (See Figure 2b).
[094] In certain embodiments, the leakage flow through the transverse slot 162 can be reduced or eliminated by incorporating a series or plurality of magnets 138 on a periphery of the rotor hub 134. A plurality of magnets 138 can be oriented similar to those cylinder magnets 106 of cylinder 100 (not shown in Figure 3). In certain embodiments, a plurality of magnets 138 will move with rotor assembly 130.
[095] In other embodiments, the iron core 132 may consist of two or more segments 140a and 140b that can be fastened together to form a complete ring or core. This configuration can have the benefit of allowing a plurality of coils to be constructed in conventional ways and then added to the ring segments.
[096] Figure 4 illustrates an isometric view of the rotor assembly 130 in which the core 132 comprises the core segment 140a and the core segment 140b. A single coil 142a is positioned around core segment 140a. In certain embodiments, there may be a plurality of coils 142 as illustrated in Figure 5.
[097] Figure 5 is a side cross-sectional view of one embodiment of an electric motor/generator assembly 150 that incorporates the magnetic cylinder 100 and the rotor hub 134. Figure 6 is a longitudinal cross-sectional view of the assembly of electric motor/generator 150. The motor/generator assembly 150 may use components similar to the components discussed above, such as the magnetic cylinder 100 and the rotor hub 134. Figure 7 is a side cross-sectional view of one embodiment. of an electric motor/generator assembly 150 illustrating additional details regarding the current paths between individual coils in a plurality of coils 142. The coils illustrated in Figure 7 are connected in series, but any combination of series or parallel connections are possible. Additional brush locations can be added depending on design criteria and needs.
[098] In illustrative mode, the motor/generator assembly 150 has a longitudinal axis 152. In certain embodiments, the longitudinal axis 152 may be made of an iron or a ferrite compound with magnetic properties similar to iron. In some embodiments, the ferrite compound or powder can be suspended in a viscous material, such as an insulating liquid, an insulating liquid, a lubricant, motor oil, gel, or mineral oil.
[099] In certain embodiments, there may be an outer casing or housing 154 that provides structural support for the magnetic cylinder 100 and the longitudinal axis 152. In certain embodiments, the housing 154 may be formed of any material, alloy, or compound it has. the required structural strength. In certain embodiments, non-ferrous materials can be used. In some embodiments, outer bearings 156 (Figure 6) can be used to reduce friction between the longitudinal axis 152 and the housing 154 or similar support structure. In certain embodiments, housing 154 may be coupled to a base 158 to provide structural support for housing 154.
[0100] As described with respect to Figures 1a, 1b and 2, the toroidal magnetic cylinder 100 may comprise a plurality of outer magnets 106 forming the outer wall 102, a plurality of inner magnets 108 forming the inner wall 104. , there may be a first side wall 170 and an opposite side wall 172 that includes a plurality of outer side outer magnets 168 (see Figures 5 and 6).
[0101] In certain embodiments, the core 132 as discussed above is positioned concentrically around a longitudinal axis 176 and within the inner cavity 124 of the magnetic cylinder 100. As described above, a transverse slot 162 is formed within the inner wall 104 of the Magnetic cylinder 100 allows a portion of rotor hub 134 to be positioned within internal cavity 124. Rotor hub 134 is also coupled to core 132 which is also positioned within internal cavity 124 of magnetic cylinder 100.
[0102] A plurality of coils 148, such as coil 148a are positioned radially around core 132 to form a coil assembly 182. Each individual coil 178a in coil assembly 182 may be made of a conductive material such as wire of copper (or a similar alloy) and can be constructed using sets of conventional winding procedures known in the art. In certain embodiments, the individual coils 178a may be essentially cylindrical in shape by being wound around a coil core (not shown) that has a central opening sized to allow the individual coil 178a to be secured to the core 132.
[0103] Although a particular number of coils in the plurality of coils 142 is illustrated in Figures 5 and 7, depending on the power requirements of the motor/generator assembly, any number of coils can be used to assemble the coil assembly 182.
[0104] In certain embodiments, as illustrated in Figure 6 and Figure 7, a plurality of slip ring segments 184 electrically connect to each other the individual coils 142a in coil assembly 182 in series. Other configurations of coil connections, slip rings and brush pickup/injection points can be used. For example, other arrangements may use two non-segmented slip rings and coils in parallel connection with each other.
[0105] In some embodiments, the slip ring segments 184 are in electrical communication with a current source through a plurality of brushes 186 and 188 (Figure 6) which can also be positioned within the housing 154 to supply current to a the plurality of coils 142 in coil assembly 182. In certain embodiments, brush 186 can be a positive brush and brush 188 can be a negative brush. In certain embodiments, an inductive coupling can also be used to transfer power to the coils or vice versa.
[0106] When in "motor mode", electrical power is applied to power terminals 190 and 192, certain coils in the plurality of coils 142 move through magnetic cylinder 100 and only "see" similar "flux walls" to flow walls discussed above with reference to Figure 2b. The plurality of coils 142 is not substantially affected by the direction of flow within the core 132, thus the plurality of coils move according to the "right hand rule" along cylinder 100. However, during the short period of time in Since certain coils of a plurality of coils 142 are outside the magnetic cylinder 100 itself and making a path through the open segment 194, it is possible that they also contribute to the production of torque. During this transition period, the flux is now leaving the core 132 in its path to the outer walls of the magnetic cylinder 100 which is in the opposite direction to the flux forces within the magnetic cylinder, so each coil in the plurality of coils 142 needs to be provided with a reverse polarity to contribute to torque.
[0107] In the contact area for the negative brush 188, the current is divided into two paths, one path is back through the plurality of coils within the magnetic cylinder 100 itself, the other path is routed through the coils positioned in the open segment 194. Thus, the individual coils in the plurality of coils 142 are automatically provided with the correct polarity as illustrated in Figure 7.
[0108] In generator mode, when the plurality of coils 142 move through the magnetic cylinder 100 as a result of the rotation of the shaft 152, the coils within the magnetic cylinder see only the "flux walls" (as discussed with reference to Figure 2b). They may not be affected by the direction of flow within the core, so the coils produce power along the path through the magnetic cylinder 100. However, during the short period of time they are outside the cylinder 100 itself and making a path through of the open segment 194, it is possible that the coils also contribute to the power output. During this transition period when the coils are in the open segment 194, the flux is now leaving the iron core 132 in its path to the outer walls 102, 104, 170 and 172 of the magnetic cylinder 100 which is, however, in the direction opposite to the flow forces within the magnetic cylinder. Thus, coil assembly 182 can also produce useful power that can be utilized depending on project needs.
[0109] If it is desired to remove the open segment coil from the circuit, a diode rectifier can be added to one side of each coil to limit current flow to a specific direction.
[0110] As is well known, almost all conventional magnets have magnetic poles. Magnetic poles are typically either of the two regions of a magnet, typically called north and south, where the magnetic field or flux density is strongest. Figures 8a through 8d illustrate typical permanent magnet combinations that can be used in magnetic cylinders or rings or to create the concentrated flux densities of a magnetic pole (such as the north pole or south pole). Such magnets can be traditional magnets, electromagnets, or a hybrid permanent electromagnet discussed later in this application. In addition, iron, iron powder or other magnetic material can be added to the core area of the cylinder for increased magnetic flux concentrations and densities (not shown).
[0111] Instead of using a magnetic cylinder 100 as described above, a magnetic ring or reciprocating cylinder 200 can be produced from a single row of magnets as illustrated in Figure 8a. As illustrated in Figure 8a, all like or similar poles (eg, south pole) of the plurality of magnets 202, such as magnet 202a, face inward. Such a magnetic ring 200 can be used in a motor or generator, but the magnetic field strength or the flux field strength (and therefore the motor or generator) would depend primarily on the resistance of the individual magnets 202a in the plurality of magnets 202.
[0112] Figure 8b is an isometric illustration of a portion 210 of a magnetic ring, each portion 210 comprising a magnet 212 and a magnet 214. The positioning of magnet 212 and magnet 214 so that a magnetic ring has a The cross-sectional shape of a "V" as illustrated in Figure 8b and where the poles are facing each other increases the magnetic field strength or the flux density at the neck even though the resistance of the individual magnets remains the same. For purposes of this disclosure, such a configuration may be known as a "2x" magnet cylinder assembly, where the term "x" indicates the approximate increase in flux density per surface area of the magnet (and not necessarily the number of magnets used). Such a configuration can increase the flux density approximately twice the selected pole exit area 211. The collapse or compression of the "V" further concentrates the flux density, but at the expense of a smaller exit area 211.
[0113] Figure 8c is an isometric illustration of a portion 220 of a magnetic ring, each portion 220 comprising a magnet 222, a magnet 224 and a magnet 226. The positioning of magnet 222, magnet 224 and magnet 226 so that a magnetic ring has a "U" cross-sectional shape as illustrated in Figure 8c and where the similar pole face of each magnet is facing inwardly increases the magnetic field strength or flux density even though the resistance of the individual magnets remains the same. For the purposes of this disclosure, such a configuration may be known as a "3x" conceptual magnet cylinder assembly. Such a configuration can increase the flux density approximately three times in the selected pole output area 221. The collapse or compression of the "U" (ie, the movement of magnet 224 towards magnet 222) further concentrates the flux density, but at the expense of a smaller exit area 221.
[0114] Figure 8d is an isometric illustration of a portion 230 of a magnetic ring, each portion 230 comprising a magnet 232, a magnet 234, a magnet 236, a magnet 238 and a magnet 240 (not visible in Figure 8d ). Positioning magnet 232 opposite magnet 234 so that similar poles thereof are facing each other and positioning magnet 236 opposite magnet 238 so that similar poles thereof are facing each other. In other words, all the south poles of magnets 236 through 238 face inward. In addition, a magnet 240 is positioned on the back face of the "tube" formed by magnets 232 to 238 to create an open box or cube shape as illustrated in Figure 8d. For the purposes of this disclosure, such a configuration may be known as a "5x" conceptual magnet cylinder assembly. Such a setting can increase the flux density by approximately five times in the selected 231 pole output area. Collapsing or compressing the box area (eg, moving magnets 236 toward magnet 238) further concentrates the flux density, but at the expense of a smaller exit area 231.
[0115] For the sake of brevity and clarity, a description of those components or parts that are identical or similar to those described above will not be repeated here. Reference should be made to the above paragraphs with the following description to arrive at a full understanding of the alternative modalities.
[0116] Turning now to Figures 9a to 9f, an alternative modality or a 3x design that concentrates the magnetic field or flux lines to improve the efficiency of the motor or generator is presented. Figure 9a is an isometric exploded view of a cylindrical magnetic coil assembly 300. Figure 9b is an isometric view of the assembled cylindrical magnetic coil assembly 300. Figure 9c is a longitudinal sectional view of the assembled cylindrical magnetic coil assembly 300 inside a motor/generator assembly 350. Figure 9d is a longitudinal sectional view of the cylindrical magnetic coil assembly mounted 300 within a motor/generator assembly 350 showing a brush system electrically coupled to various coils of the assembly. cylindrical magnetic coil. Although four brushes per toroidal cylinder are shown, the actual number of brushes depends on well-known engineering factors such as wear and current-carrying capacity.
[0117] Turning now to Figures 9a and 9b, there is an improved flux 300 toroidal nuclear magnetic cylinder assembly. In some respects, many of these components of cylinder assembly 300 are assembled using the improved magnetic cylinder concepts as described above. Note that only one pole (ie, North or South) is used and concentrated along the length and amplitude of magnetic cylinder 300.
[0118] In certain embodiments, a conductor-packed coil assembly 310 comprises a core 312 that may be formed of iron, iron powder composite or other magnetic/non-magnetic core material. A conductive material 314, such as copper wire, is wound around the core 312 to form one or more coils. Thus, coil assembly 310 may consist of one or more coil segments. Especially in brushless designs, multiple coil segments allow speed control by selectively connecting coil segments in different combinations of parallel and series connections without changing the system supply voltage. For exemplary purposes, certain embodiments of coil assembly 310 may comprise twenty-four ("24") coil segments that allow for multiple possible combinations of series/parallel connections that result in multiple output speeds or output power. Where a continuously variable speed or torque requirement is required, input voltages can be adjusted accordingly and, if necessary, in combination with simple step-switched or relay control of the series/parallel connections between the coil segments. Coil assembly 310 generally has a ring shape that allows an inner longitudinal magnetic cylinder 315 to slide through central opening 316 of the coil assembly.
[0119] As illustrated, the internal magnetic cylinder 315 comprises a series or plurality of magnets 318 in which the north poles are facing radially outward and transverse to the longitudinal axis 302. Thus, when assembled the north poles of the plurality of magnets 318 would be facing the core 312 of the coil assembly 310. A first side end magnet ring assembly 320 is positioned proximate the coil assembly 310. In certain embodiments, the first side end magnet ring assembly 320 comprises a plurality of magnets 322 disposed in a radial pattern in which the poles of each magnet 322a in the plurality of magnets are generally aligned parallel to a longitudinal geometric axis 302. As illustrated, the north poles of the plurality of magnets 322 are facing inwardly toward the core 312 or the assembly. of coil 310.
[0120] In certain embodiments, a second set of end or side magnetic ring 330 comprises a plurality of magnets 332 arranged in a radial pattern wherein the poles of each magnet 332a in the plurality of magnets are generally aligned parallel to the longitudinal geometric axis 302. As illustrated, the north poles of the plurality of magnets 332 face inwardly toward the coil assembly 310.
[0121] When assembled, it is evident from the discussion referring to Figures 8a through 8d that coil assembly 300 uses a 3x flux concentrate design to concentrate the magnetic fields or the intensity of the flux force.
[0122] Figure 9c is a longitudinal cross-sectional view of one embodiment of an electric motor/generator assembly 350 that incorporates the magnetic cylinder 300. The motor/generator assembly 350 may use components similar to the components discussed above, such as the magnetic cylinder 100 and the rotor hub 134.
[0123] In illustrative mode, the motor/generator assembly 350 has a longitudinal axis 352. In certain embodiments, the longitudinal axis 352 can be produced from a compound of ferrite, steel or iron with magnetic properties similar to iron. In certain embodiments, the longitudinal axis 352 can include a powder or ferrite compound. In some embodiments, the ferrite powder or compound can be suspended in a viscous material, such as an insulating liquid, a lubricant, motor oil, gel, or mineral oil to reduce or eliminate eddy currents and magnetic hysteresis.
[0124] In certain embodiments, there may be an outer housing or casing 354 that provides structural support to the magnetic cylinder 300 and the longitudinal axis 352. In certain embodiments, the housing 354 may be formed from any material, alloy or compound it has. the required structural strength. In certain embodiments, non-ferrous materials can be used. In some embodiments, outer bearings (not shown) can be used to reduce friction between the longitudinal axis 352 and the housing 354 or similar support structure. In certain embodiments, housing 354 may be coupled to a base (not shown) to provide structural support for housing 354.
[0125] As illustrated in Figure 9c, the magnet cylinder 300 can be a 3x brushless assembly in that the magnet assembly (for example, the longitudinal magnet cylinder 315, the first side magnet ring 320, and the second side magnet ring 330) acts as the rotor with the toroidal coil assembly 310 stationary. This configuration has the advantage of using coil segments whose conductor guides can be brought to a single location (not shown) which allows stepping speed control by simply switching series/parallel combinations in combination with varying input inputs. voltage at which stepless control of motor/generator outputs is desired. A connecting hub 317 couples the magnetic cylinder 315 to the shaft 302 in a conventional manner.
[0126] Figure 9d illustrates the magnetic cylinder 300 as a 3x concentrated brushed “sidewall” brush assembly. This assembly can be easily incorporated into a modular 500 assembly illustrated in Figures 11a through 11d below. In certain embodiments, the modular assembly 500 can be a modular screw assembly that allows greater flexibility in selecting different electrical and mechanical outputs without major design changes. Engineering needs and design consideration will determine the maximum numbers of magnetic cylinder assemblies and coils.
[0127] Turning now to Figures 10a and 10b, an alternative modality or a 3x design is presented that concentrates the magnetic fields or flux lines 401 to improve the efficiency of a motor or generator 450. Figure 10a is a view in longitudinal section of the mounted magnetic cylindrical coil assembly 400 within the motor/generator assembly 450 where a coil segment 410a is not in an energized state. Figure 10b is a longitudinal cross-sectional view of motor/generator assembly 450 when coil segment 410a is in an energized state (ie, current/voltage is moving through conductive material 414.
[0128] The enhanced flux toroid nuclear magnetic cylinder assembly 400 is similar to the core magnetic cylinder assembly 300, except that the inner parallel magnet cylinder 315 is positioned on the outside of the side magnet ring assemblies 420 and 430.
[0129] In certain embodiments, a conductor-packed coil assembly 410 comprises a core 412 that may be formed of iron, iron powder composite, or other magnetic/non-magnetic core material similar to core 312 discussed above. A conductive material 414, similar to conductive material 314, is wrapped around core 412 to form one or more coils or coil segments such as coil segment 410a. Thus, coil assembly 410 may consist of one or more coil segments as described above with reference to coil assembly 310.
[0130] The coil assembly 410 generally has a ring shape that allows a connecting hub 417 to couple the coil assembly 410 to a longitudinal axis 452. In certain embodiments, the connecting hub can be coupled to the slip rings ( not shown) or bushings 419.
[0131] As illustrated, the outer magnetic cylinder 415 comprises a series or plurality of magnets 418 in which the north poles are facing radially inward toward the core 412 and the longitudinal axis 402. A first set of lateral magnetic ring 420 is positioned proximate to coil assembly 410. In certain embodiments, first side magnetic ring assembly 420 comprises a plurality of magnets 422 disposed in a radial pattern wherein the poles of each magnet 422a in the plurality of magnets are generally aligned parallel with a longitudinal axis 402. As illustrated, the north poles of the plurality of magnets 422 face inwardly toward the core 412.
[0132] In certain embodiments, a second side magnetic ring assembly 430 comprises a plurality of magnets 432 arranged in a radial pattern wherein the poles of each magnet 432a in the plurality of magnets are generally aligned parallel to the longitudinal axis 402 As illustrated, the north poles of the plurality of magnets 432 face inward toward the core 412.
[0133] In illustrative mode, the motor/generator assembly 450 has a longitudinal axis 452. In certain embodiments, the longitudinal axis 452 may be similar to the longitudinal axis 352 discussed above.
[0134] In certain embodiments, there may be an outer housing or housing 454 (similar to housing 354 discussed above) that provides structural support for coil assembly 410 and longitudinal axis 452. In some embodiments, outer bearings (not shown) may be used to reduce friction between the longitudinal axis 452 and the housing 454 or similar support structure.
[0135] As illustrated in Figures 10a and 10b, the magnet cylinder 400 can be a 3x brushless assembly in that the magnet cylinder assembly 400 (for example, the outer magnet ring 414, the first side magnet ring 420 and the second side magnetic ring 430) acts as the stator with the toroidal coil assembly 410 acting as a rotor.
[0136] Figure 10a illustrates the representative flow paths in a 3x magnetic cylinder assembly section before energizing the coils. When a current is established in the coil segment 410a, the permanent magnet flux lines 401 of Figure 10a are forced out of the coil segment 410a and are compressed in the remaining space between the magnetic rings and the core or coil segment 410a as per illustrated in Figure 10b. A Lorentz force is then transmitted to the rotor causing rotation in the case of a motor and an induced current flow in the case of a generator. The transmitted force or the established voltage/current flow is indicated by the Lorentz force calculations.
[0137] In a motor, the force is equal to the flux density in Tesla times the amperage times the conductor length in meters. In a generator, the voltage is equal to the flux density in Tesla times the speed times the conductor length in meters. In all configurations presented in this order these basic calculations are used.
[0138] Turning now to Figures 11a to 11d, an alternative modular modality is presented in which each module uses a 3x design that concentrates the magnetic field or flux lines to improve the efficiency of the motor or generator. Figure 11a is an isometric view of the assembled cylindrical magnetic coil assembly 500. Figure 11b is a longitudinal isometric cross-sectional view of the assembled cylindrical magnetic coil assembly 500 within a motor/generator assembly 550. Figure 11c is a view in longitudinal section of cylindrical magnetic coil assembly 500 mounted within a motor/generator assembly 550. Figure 11d is a longitudinal sectional view of cylindrical magnetic coil assembly 500 mounted within a motor/generator assembly 550 showing a exemplary brush system electrically coupled to various coils of the cylindrical magnetic coil assembly.
[0139] Turning now to Figures 11a and 11b, there is an improved flux 500 toroid nuclear magnetic cylinder assembly. In some respects, many of these components of cylinder assembly 500 are assembled using the enhanced magnetic cylinder concepts as described above. Magnet assembly 500 is essentially three magnet cylinders 100 (discussed above) mounted longitudinally as a single cylinder assembly (with certain polarities reversed, as explained below) and on a common shaft.
[0140] In certain embodiments, conductor-wrapped coil assemblies 510a through 510c include cores 512a through 512c similar to the core 312 discussed above. The cores 512a to 512c can be formed from iron, iron powder composite or other magnetic/non-magnetic core material. Conductive materials 514a to 514c, such as copper wire, are individually wrapped around cores 512a, core 512b, and core 512c to form one or more coil segments for each coil assembly 512a to 512c. As discussed above, multiple coil segments in each coil assembly 510a through 510c allow speed control by selectively connecting coil segments in different combinations of series and parallel connections without changing the system supply voltage.
[0141] Coil assemblies 510a to 510c generally have a ring shape that allows internal magnetic cylinders 514a to 514c to be positioned annularly with respect to a longitudinal axis 502. A plurality of hubs, such as the hub 516a to 516c couples a longitudinal axis 552 to internal magnetic cylinders 515a to 515c.
[0142] As illustrated, each of the internal magnetic cylinders 515a to 515c comprises a series or plurality of magnets 518 positioned so that the magnetic poles thereof are radially aligned perpendicularly to the longitudinal axis 502. A first set of magnetic ring End cap 520 is positioned close to coil assembly 510a. In certain embodiments, the first end magnetic ring assembly 520 comprises a plurality of magnets 522 disposed in a radial pattern wherein the poles of each magnet in the plurality of magnets are generally aligned parallel to a longitudinal geometric axis 502 (similar to the ring assembly 320 discussed above). As illustrated, the north poles of the plurality of magnets 522 face inwardly toward the core 512a.
[0143] In certain embodiments, a second set of end magnetic ring 530 comprises a plurality of magnets 532 arranged in a radial pattern wherein the poles of each magnet 532a in the plurality of magnets are generally aligned parallel to the axis. longitudinal 502. As illustrated in Figures 11c and 11d, the north poles of the plurality of magnets 532 face inwardly toward the core 512c.
[0144] As illustrated in Figures 11c and 11d, the magnetic cylinder 500 may include three "magnetic cylinders" 500a, 500b and 500c spaced longitudinally from each other and sharing the same axis 552 and geometric longitudinal axis 502. magnetic cylinder 500, individual magnetic cylinders 500a, 500b and 500c change magnetic polarities. For example, the north pole of magnet 515a faces outward toward core 512a. However, the north pole of magnet 515b faces inward away from core 512b. Similarly, the north pole of magnet 515c faces outward toward core 512c. This pattern would continue if more individual magnetic cylinders were added to the 500 magnetic cylinder assembly.
[0145] In other words, the space filled by core 512a for individual magnetic cylinder 500a has a magnetic force filled with a "north pole" polarity from the placement of magnets 522, magnets 515a, and magnet ring magnets 524 On the other hand, the space filled by the core 512b for the single magnetic cylinder 500b has a magnetic force filled with a "south pole" polarity from the positioning of the magnet ring magnets 524, magnets 515b, and magnet ring magnets 526. The space filled by the core 512c for the individual magnetic cylinder 500c has a magnetic force filled with a "north pole" polarity from the placement of the magnets from the magnet ring 526, the magnets 515c, and the magnets from the magnet ring 532 .
[0146] In certain embodiments, the longitudinal axis 552 can be produced from a composite of iron, steel or ferrite with magnetic properties similar to iron. In certain embodiments, the longitudinal axis 552 can include a powder or ferrite compound. In some embodiments, the ferrite powder or compound can be suspended in a viscous material, such as an insulating liquid, a lubricant, motor oil, gel, or mineral oil to reduce or eliminate eddy currents and magnetic hysteresis.
[0147] In certain embodiments, there may be an outer housing or casing 554 that provides structural support to the magnetic cylinder 500 and the longitudinal axis 552. In certain embodiments, the housing 554 may be formed of any material, alloy or compound that has the strength required structure. In certain embodiments, non-ferrous materials can be used. In some embodiments, outer bearings (not shown) can be used to reduce friction between longitudinal axis 552 and housing 554 or similar support structure. In certain embodiments, housing 554 may be coupled to a base (not shown) to provide structural support to housing 554.
[0148] In this example, the magnetic cylinders 500a to 500c include a brushless or 3x concentration assembly in that the magnet assembly (for example, the magnet ring or cylinder 515, the first side magnet ring 520 and the second side magnetic ring 530) acts as the rotor with the 510 stationary toroidal coil assembly. This configuration has the advantage of using coil segments whose conductor guides can be brought to a single location (not shown) which allows stepping speed control by simply switching series/parallel combinations in combination with varying voltage inputs in that stepless control of the motor/generator outputs is desired.
[0149] Figure 12 is a longitudinal cross-sectional view of one embodiment of an electric motor/generator assembly 650 that incorporates an enhanced flux magnetic cylinder 600. The motor/generator assembly 650 may use components similar to the components discussed above , such as coil assembly 610. In some respects, many of these components of magnet cylinder assembly 600 and motor/generator assembly 650 are assembled using the improved magnet cylinder concepts as described above.
[0150] In certain embodiments, the conductor-wrapped coil assembly 610 comprises a core 612 similar to the core 312 discussed above. A conductive material 614, such as copper wire, is wrapped around core 612 to form one or more coil segments 610a. Coil assembly 610 is generally ring-shaped and may be coupled to a connecting hub or tether ring assembly 617 which may, in turn, be coupled to a shaft 652.
[0151] As illustrated, the flux enhanced toroidal magnetic cylinder assembly 600 comprises three U-shaped magnetic cylinders 680, 682 and 684 in which the open end face of each U-shaped cylinder faces the core 612 or the assembly of coil 610. Each of the U-shaped magnetic cylinders is made up of a series or plurality of magnets 618 with the north poles of each magnet facing inward toward the "U" space. Thus, when assembled, the north poles of the plurality of magnets 618 are facing core 612 to concentrate the magnetic fields of the magnets.
[0152] The 600 coil assembly uses a 9x flux concentrator design (three concentrations of 3x). Thus, the assembled 650 motor/generator has a 9x magnetic concentration and uses a typical 619 DC brush (although four are shown, any number can be used depending on engineering factors) to transmit or collect current. In this particular embodiment, the toroidal coil assembly 610 acts as the rotor which is connected to a slip ring assembly 642. The 9x magnet ring or cylinder assembly acts as the stator. The greater flux density acting on the conductors increases the Lorentz outputs in motor or generator mode.
[0153] In illustrative mode, the motor/generator assembly 650 has a longitudinal axis 652, similar to the axis 352 discussed above.
[0154] In certain embodiments, there may be an outer casing or housing 654 that provides structural support to magnet cylinder 600 and longitudinal axis 652.
[0155] Figures 13a and 13b illustrate a hybrid electromagnet magnet 700 assembly that can be incorporated into certain aspects of the magnetic cylinders to concentrate the magnetic fields. In addition, iron cores or similar materials can also be used with the magnetic cylinders to concentrate the magnetic fields as described above.
[0156] In certain embodiments, magnet assembly 700 comprises at least two or more commercially available permanent magnets 710 and 712 positioned at either end of iron core 714. In the illustrated embodiment, a cylinder shape was selected, but any format can be built in any suitable configuration.
[0157] Figure 13a illustrates conceptual flux lines 716 of the hybrid magnet assembly 700. A person skilled in the art can see that although some of the aligned magnetic domains will contribute to the output of the flux lines 716 from the pole faces of the permanent magnets, however, most will "leak" out of the sidewalls of core 718.
[0158] Figure 13b illustrates the hybrid magnet assembly 700 with a spirally packed conductive material 720 that carries a current. As illustrated, conductor 720 confines and concentrates all flux lines 716 to align any magnetic domains not aligned by the permanent magnets. This addition allows for the creation of much stronger magnetic flux outputs at lower ampere turn levels than conventional iron core coils.
[0159] Thus, such "hybrid" magnet assemblies can also be used to assist in concentrating flux force lines in the magnetic cylinders discussed above.
[0160] In summary, certain aspects of the various modalities revealed can provide the following benefits:
[0161] Unlike conventional brush-ground or PWM controller motor/generators, the coils in aspects of this invention are in continuous contact with the permanent magnet field and thus produce a continuous non-variable torque or output.
[0162] Complex PWM drivers and controllers, switches, etc. (and the associated losses) may not be required as certain aspects of the invention directly produce and utilize a DC current.
[0163] If automatic speed control for a given load is required, a complex position indication is not required. A much simpler RPM indication and variable voltage/current relationship is the only requirement.
[0164] Using the single magnet/magnetic cylinder concept that utilizes permanent magnets, an extremely strong, otherwise unreachable magnetic field is generated without consuming any electrical power.
[0165] Although a Reverse Driving Force field is produced through any induced current flow, due to the magnet core and cylinder design there is no direct impact on the coil motion that would prevent such motion.
[0166] Iron hysteresis losses are essentially eliminated since only two points in the nucleus experience any hysteresis loss and then only twice per revolution.
[0167] Eddy current losses are essentially eliminated as the core does not move perpendicular to the flow lines
[0168] Roughing is also essentially eliminated as core forces are balanced and equal in all directions.
[0169] There is little inrush current as there is no need to saturate large masses of iron
[0170] 100% of the copper windings in the coil is used to take advantage of Lorentz forces, so there is no wasted copper winding as in conventional motors/generators.
[0171] Inductor feedback from descending and ascending waveform is eliminated.
[0172] Like other DC motors, torque reversal is simply a reversal of input polarities.
[0173] The above description of the embodiments of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many combinations, modifications and variations are possible in light of the above teachings. Undisclosed embodiments which have interchangeable components are also within the scope of the present invention. It is intended that the scope of the invention be limited not by this detailed description, but rather by the appended claims.
