According to FIG. 1 and 3, each measles 3.1 (3.2) contains a core winding 5.1 (5.2) and an annular root magnet duct 6.1 (6.2), both of which are recessed in plastic, the connecting ring located in the inner space with them 7.1 (7.2) is also partially yTonJTeHHoe in plastic 8, the peripheral part of which is associated with plastic 9.1 (9.2).

Anchor magnetic circuit 6.1 (6.2) is formed by encircling the magnetic tape in rings, and the root winding 5.1 (5.2) is located on its side, facing the rotor i.
The connecting ring 7.1 (7.2) contains a multitude of electrically conductive segments, isolated from each other, to the ends of which are pinched, coils are formed, forming the main winding 5.1 (5.2). Electrical conductors 12.1, 12.2 (Fig. 1) connecting the segments of the connecting ring with external electronic switching circuits, are attached with screws 13 to the corresponding segments (Fig. 11) and pass through channels 11.1 (11.2) parallel to the axis engine in flange 2.1 (2.2).

insert into the carbox fiber support, which has a recess, with all the gg being recessed in the synthetic cr-yule, rigidly connected, to it the rotor; sleeve mounted on the shaft 16 of the engine, Since the magnetic ijC; - Just knuckle magnets 19, preferably made from Samari-cobalt bakers, are parallel to the motor shaft 16, the magnets create magnetic fields parallel to the shaft. The thickness of the permanent magnets 19 is slightly larger than the thickness of the housing 18. The permanent magnets 19 are evenly distributed on the peripheral part of the rotor 1 and are arranged in such a way that
on each surface of the rotor there are polar divisions (Fig. 12).
the surfaces following each other around the circle have different polarity, forming on each surface of the rotor three pairs of uniformly distributed poles. In general, the number of pairs of poles can be arbitrary. The permanent magnets 19 move in the air gap between the sides of the rings of the magnetic cores 6.1 and 6.2 of the two halves of the stators facing the rotor, and the size of this air gap is determined by the thickness of the flat core windings 5.1 (5.2) embedded in plastic
9.1 (9.2), and the necessary air gap between the stator and the rotor. The magnetic field of the permanent magnets is closed through the sheets of the ring of the magnetic cores 6.1 and 6.2, so the flanges 2 and 2.2 can be made of a non-magnetic material, such as aluminum. The rings of the magnetic core 6.1
and 6.2 are made of twisted steel magnetic tape, and this tape is provided with insulating layers that prevent the occurrence of Foucault currents. The rings of the magnetic circuit 6.1 and
6.2 can be made by another known method, for example, pressing a steel powder with a bonding substance, while the steel particles are oriented in such a way that the conductivity in the radial direction is extremely small or there is no TH-ccH, which prevents the appearance of Foucault currents.
Each root winding 5.1 (5.2) is made in the form of a loop winding of conventional DC collector motors. It consists of coils which partially mutually overlap in a known manner (Fig. 4). In total there are coils, where p is the number of pole pairs on one side of the rotor; m is the number of sections associated with the output of the electronic switch. In this example, and, so that each root winding consists of twenty-four coils (Fig.6

60594
and 12). FIG. 6 and 12 coils schematically depicting 1y one coil; in practice, a coil may contain many turns (Fig. 5). The two surfaces of each coil, which intersects the magnetic field of the permanent magnets, are located at a distance equal to one pole. A connecting ring 7.1 is used for mounting individual coils (7 , 2). This ring is divided (FIG. 6) into segments isolated from each other.
other number equal to the number of coils, i.e. into twenty four segments 20.1 - 20.24 in the considered example. These segments of conductive
material, for example copper, is separated by radial grooves 21 filled with plastic to hold these segments together in the form of a connecting ring 7.1 (7.2). The axial sections in FIG. 3, 10 and 11 show
profile of the connecting ring 7.1 of one of its segments 20.1. A recess 22 is provided at the outer edge of each segment (FIG. 3) for holding by wedging the ends of the coils. In addition, the connecting ring 7 has, on the part adjacent to the part having grooves 22, and somewhat smaller diameter than this last, the first circumferential circumferential groove 23 (FIG. 10), the second annular
a groove 24 on its inner circumference and a third groove 25 on its lateral surface facing the rotor in an assembled state.
As shown in FIG. 12, the two ends of each coil 26.1 to 26.24 are connected to two adjacent segments of the connecting ring, with the end of one coil and the beginning of the other connected to the same segment. The end of the coil 26.24 and the start of the coil 26.1 are thus connected to the same segment 20.1, as can be seen in FIG. 6, with the two ends of the coil connected by joint wedging in the recess 22 (FIG. 11). The beginning of the coil 26.2 and the end of the coil 26.1 are connected together to a segment
20.2, the end of the coil 26.2 and the beginning of the next coil 26.3 are connected together to an adjacent segment of 20.3, etc. All reels that have the same location relative to
one pair of poles, i.e. relative to two adjacent poles and, therefore, shifted relative to each other by the magnitude of the two pole divisions, excited by the current of one direction, direction, and therefore connected in parallel. According to FIG. 12, in parallel, the coils should be connected in each of the eight groups of three: 26.1-26.9-26.17; 26.2-26.10- 26.18, etc. to 26.8-26.16-26.2A.
In order to simplify the circuit of the electron switch that controls the current of the coils, these parallel connections are made in the coupling ring 7.1. Three segments making up connections for one or the other ends of the three coils of each group of three are interconnected by conductors. Segments 20.1, 20.9 and 20.17 are thus connected together by conductor 27.1, segments 20.2, 20 .. 10 and 20,18. by conductor 27.2, etc. and.

The communication conductors preferably extend along the side of the connecting ring facing the rotor along the partition wall of this ring in the groove 25, as shown for conductors 27.1 and 27.2 in FIG. 6. They are soldered to the corresponding segments until the end of the assembly of the connecting ring and before the coils are connected, or fixed by jamming in the holes or recesses provided for this one. The connecting ring is then recessed in the plastic using a suitable form along its inner circumference and along the side having groove 25, whereby the plastic simultaneously fills the radial grooves 21 separating the segments from each

A sufficiently strong current is passed through the finished coil so that the insulation of the wire, made of synthetic resin, is softened and that after cooling, the cooling coil of the insulation of the connecting wires is glued together. Thus, a hard rigid coil in the form of a flat basket is obtained, the peripheral zone of which, containing a large number of conductors superimposed on each other parts of the coils, forms a roll in the form of a roller, partially bent on one side.

Groups of three segments form eight connections, which are controlled separately and should be brought outside by conductors 12.1-12.8. To be able to conveniently connect these eight conductors to the connecting ring, every third segment of the connecting ring has
a width equal to twice the width of the D :: - segments, and provided with a screw 13 for connections to the conductor leading outwards. In the example (FIG. 6), we are talking about segments 20.1, - 20.225 which have connecting BINTS 13, shown in FIG. 3 and 11, In the assembled engine, the conductors 12.1 - 12.85 reaching the line: “y (Fig. 12), are brought out through the channels 11.1 (11.2), made in the flange of the corresponding stator.

so that there is still a zone 31 on the side of the ring opposite to the groove 25, so as to hold together the connecting ring with the segments 20.1, 20.2, etc., formed in this way. B middle of the segments 20. 1, 20.2, etc. Grooves 32, less deep than grooves 21, are also milled in which conductors 27.1-2.78 are fixed, intended to connect the described pairs of segments, with conductors 27 arranged along an arc of a circle inside groove 25. In FIG. 10 shown
axial section of the treated ring - 15 to 6.1 installed on the outer
with schematically shown conductors 27.1-27.8, bent along the arc of a circle, which must be entered into the groove 25..
A connecting ring 7.1 (7.2) with conductors 27.1-27.8 is then placed in an annular shape and embedded in plastic. During this operation, the conductors 27.1-27.8 are completely recessed into the plastic, k, the fill fills the groove 25, the plastic also covers the inner circumference of the connecting ring, filling the annular groove 24, and the outer circumference of the connecting ring, filling the annular groove 23. The plastic also fills the radial grooves 21 and, penetrating the radial and annular grooves, provide a strong bond with the metal ring. Then cut out segments 20.1, 20.2, etc. in the middle. and notches 22 (FIGS. 10 and 11) and make the threaded holes 13 (FIG. 10) in the segments with which conductors leading to the outside will later be connected. FIG. 10 shows the recesses 22 and the screw holes 13 on the ring 7.1, but they, as mentioned above, are made only after the ring 7 is poured into the plastic 8.
The side of the connecting ring, which is opposite to the groove 25, is then processed until the solid area 31, free from the radial grooves (Fig. 10), is removed so that the segments 20.1, 20.2, etc. separated from each other, insulated and held together only by plastic 8 (Fig. 11),
The next manufacturing phase consists in securing the core winding with its coils on the connecting ring 7.1, with the ends of the individual coils attached to the corresponding
segments by jamming in recesses 22. In FIG. 11 shows the fastening of one of the ends of the coils 26.1 and 26.24 in the notch 22 of the segment 20.1. The manufacture of a block with a connecting ring is completed by installing the connecting screws 13 on the eight mentioned segments.
The last phase of the core production is to be placed in the appropriate shape of the workpiece, composed of a core winding 5.1 and a connecting ring 7.1 with a core magnet.
coil side, i.e. on the side of the coils facing the stator flange, and in its casting into plastic 9.1 (Fig. 3). Plastics 8 and 9.1 (9.2) are preferably epoxy resins. The anchor winding is thus completely recessed in plastic 9.1 (9.2), which also passes across the entire periphery of the magnetic wire 6.1 (6.2) in this example. The space between the peripheral part of the connecting ring 7.1 (7.2) and the coil connections going in the recess 22, respectively, the peripheral part of the magnetic circuit 6.1 (6.2) is filled with plastic 9.1 (9.2) to the height of the outer side of the connecting ring 7.1 (7.2).

stator flange.
In a simplified embodiment of the engine (FIG. 15), the engine has one measles 3.1 on the flange 2.1, which is similar in design to one of the cores in FIG. 1. The opposing flange is part of the housing. To close the magnetic flux circuit of the permanent magnets 19 of the rotor 1 on the side of the rotor opposite to the bore, a magnetic conductor ring 33 is fixed so that the magnetic fluxes of the permanent magnets 19 can be closed through it. Otherwise, the rotor can be made in the same way as in FIG. 1 and 2.
According to another implementation variant of the engine (Fig. 16), the rotor 1
may be in the form of a plate, while the two cores 3.1 and 3.2, located on each side, may have a shape similar to the shape of a rotor, t, e, have a conjugate and opposite taper.
FIG. 17 shows an engine variant in which the rotor 1 has a double cone shape, i.e. trapezoidal section in the axial plane, and two cores 3.1 and 3.2, located on each side on the flanges 2.1, 2.2 of the stator, with their taper are adapted to two sides, the rotor, inclined relative to the shaft 16,
The taper of the rotor (Figs. 16 and 17) gives greater rigidity necessary to avoid movement of the permanent magnets attracted axially by the steel of the stators. In addition, in the case of bicusus (Fig. 17), the main mass of the rotor 1 is located closer to the shaft 16, which reduces the moment of inertia.
In a particularly preferred form of realization of the core in the motor (Fig. 8), the space between the radially directed sides of the individual coils 26.1-26.24 can be filled with wedge-shaped parts or a sector of ferromagnetic material prior to filling the plastic winding. Details FOR have approximately the same thickness as the root winding itself, if it looks away from the motor axis, and thus strengthens the field of the core, reducing the air gap by an amount approximately equal to the thickness of the winding. At the same magnitude of the field, the permanent magnets can be m: thinner, which reduces the moment of inertia of the rotor. Parts 34 may be made of a special iron powder mixed with an adhesive mass and pressed under pressure.
Instead of a looped root winding, the wave core winding can be used, as is usually the case in DC motors. While in the loop winding, coils are successively commuted, directly adjacent to each other, in the wave winding, these are coils that are offset by an angle close to the double pole division value. In the considered example (fig. 19 and 20) the wave winding contains twenty five coils
355 connected, as shown, with a connecting ring 36J which contains twenty-five segments 37, the internal wires of the connector and the ring were removed; and a KZhp} -t segment of this ring is connected to the outer conductor 38 to be switched separately by means of an electronic switch 29,
