    "Stator for axial flow electromagnetic machine with unitary portions forming a stator ring"
    The present invention relates to a stator for an axial flow electromagnetic machine with unitary portions forming a stator ring. The invention also relates to an axial flow electromagnetic machine and a method of mounting such a stator.
    An electromagnetic machine comprises at least one stator and at least one rotor, an air gap separating these two elements. The rotor carries at least one permanent magnet, advantageously a series of permanent magnets, while at least one series of winding elements is carried by the stator.
    Conventionally, each of the winding elements comprises a core or a tooth bearing a coil, the core being framed on each of its sides by a notch, a wire good conductor of electricity being wound around the core to form the coil .
    When the series or series of windings are electrically powered, the rotor which is secured to the output shaft of the motor is subjected to a torque resulting from the magnetic field, the magnetic flux created being an axial flow for an axial flow electric machine .
    The demand for electrical machines that can deliver high power while maintaining a reduced weight and bulk is currently very strong.
    Moreover, in industrial applications, the reduction of the mass and the size of the motor for an optimal yield, the reduction of the relaxation torque and the variation of the total torque are criteria as important as the ease of realization, the mass production and the gain in manufacturing time.
    Document FR-A-2 965 125 discloses a stator for disc axial electric machine whose disk is constituted by a plurality of sectors. Each sector is composed of several modules, each module consisting of a stack of magnetic sheets having arrangements for winding at least one winding and arrangements for mounting a connecting means.
    This connection means is capable of ensuring, on the one hand, the connection of the different modules of the same sector and the different sectors between them and, on the other hand, the coupling of the sectors to a support.
    Document FR-A-2 926 935 describes an axial flux machine with permanent magnets comprising a rotor surrounding a stator. The stator comprises a first so-called support part, a set of active modules constituting the induced part of the magnetic circuit and means of securing the modules on the support part.
    The stator comprises a set of active modules constituting the induced part. Each module comprises a block consisting of a superposition of layers, two lower and upper wedges and two windings surrounding the lower and upper wedges.
    These two solutions are however not satisfactory. In particular for the electric machine described in the document FR-A-2 926 935, it is necessary to use lower and upper wedges provided with notches for receiving the windings.
    For the electrical machines described in these two documents, the stator consists of a plurality of elements, which hampers assembly and occupies space that could be more appropriately devoted to the windings.
    The problem underlying the present invention is to design a stator for an axial flow electromagnetic machine which is simple to mount and easily adaptable. For this purpose, according to the invention, a stator is provided for an electromagnetic machine with axial flow, the stator forming a ring having two circular faces, the stator being composed of several unitary portions, characterized in that each unitary portion has a core around which the winding is wound, the unitary portions forming at least partially the ring being arranged relative to one another concentrically and each having means for securing either with a support member which may or may not be part of a housing housing the ring gear, or with securing means between the adjacent unit portions fixed directly to the housing. The technical effect obtained is a simplicity of assembly. The unit portions can be manufactured long before mounting in the stator at another mounting station and are easily individually mounted in the stator. When a winding is deficient, its associated unit portion can also be removed from the stator easily, especially when each unit portion is releasably secured in the stator. It is no longer necessary to wind the coils on a core already positioned on the stator, which provides more room for winding the winding on a unit portion separate from the others than around a core already positioned on the stator. The technical effect is also a great adaptability of the stator. It is for example possible to change the series of windings of the ring by another series of windings without performing unwinding of the windings but replacing the unitary portions of the stator ring by unitary portions carrying another type of winding.
    The stator according to the present invention may therefore comprise unitary units made in series independently of the ring and comprising securing means to improve the process of industrialization of the stator assembly to reduce the time and cost of production.
    Advantageously, the support member is an integral part of the housing or is an integral insert of the housing. Such an assembly is therefore more resistant with elements integral with each other and connected to the housing or in one piece with the housing.
    Advantageously, between two cores of adjacent unit portions, there remains a free space forming a notch and, where appropriate, an isthmus formed by the edges located on the side intended to form an air gap on a first circular face of the crown, the edges of each portion. unitary of a second face of the ring opposite to the first circular face together with side projecting portions of each unit portion delimiting a cylinder head, the adjacent unit portions being arranged end to end by their edges and their parts in lateral projection. This notch allows spacing the coils from each other.
    Advantageously, the securing means are removable or permanent, the removable securing means being made by screwing or latching elements between the adjacent unit portions and the permanent joining means being made by welding, gluing or by elements of the type rivet. The removable securing means will be preferred when the unit portions are likely to be frequently dismantled.
    Advantageously, the removable securing means are effected by screwing, connecting or detent elements on the edges of the adjacent unitary portions of the second face facing each other and arranged end to end of the adjacent unitary portions. Thus, the unitary portions placed end to end make at least one continuous circular face of the stator ring.
    Advantageously, the permanent securing means are made by welding, gluing or riveting the edges facing each other and arranged end to end by the edges of the adjacent unitary portions of the second face and the support member. This makes it possible to directly secure the unit portions together and avoids using an additional support member, which represents an economy of means and a decrease in the weight of the stator.
    Advantageously, the support member has radial lights to the ring and positioned in alignment with the edges of the adjacent unit portions.
    Advantageously, the support member has securing forms associated with complementary shapes of the adjacent unit portions.
    Advantageously, the securing forms carried by the support member are insertion cleats, each insertion cleat can be semi-cylindrical in shape with a constant or variable triangular section along the length of the cleat, a vertex of the triangular section. pointing to the support member and each of the two other vertices of the triangular section being housed in a respective groove carried by an edge vis-à-vis each of the two adjacent unit portions flanking the insertion stop. This allows axial retention of the unit portions and easy positioning of the unit portions by sliding along the cleat. The half-cylindrical shape provides a substantial insertion cleat support surface for two adjacent unitary portions.
    Advantageously, the forms of attachment carried by the support member are radial lights to the crown passing through the support member forming mortises, vis-à-vis the support member of the adjacent unitary portions having a tenon penetrating into a respective mortise in mounted position of the adjacent unitary portions on the crown. A tenon and mortise connection provides a simple and effective blocking of unit portions with respect to the support member.
    Advantageously, each tenon and the associated mortise are welded together. This reinforces this mode of solidarity.
    Advantageously, when a yoke is present, an outer ring surrounds the yoke of the ring over its entire periphery. There can be no radial deflection of the unitary winding portions out of the ring by the outside of the ring. The outer ring shrinks the mechanical strength of the unitary portions in the crown.
    Advantageously, the cores of the unitary portions are made with laminated sheets, sintered magnetic materials or any other magnetic or non-magnetic material.
    Advantageously, the unit portions are of variable shapes and dimensions for the same ring. The invention finally relates to a method of manufacturing such a stator or of such an electromagnetic machine, in which it is carried out the winding of a coil on a core forming a unitary portion dissociated from the other unitary portions and it is then bonding the unit portions together and / or at least one support member to form the stator ring.
    The winding can thus be made before assembling the unitary portions thus facilitating the winding and its industrialization. The winding of the winding on each unit portion is made without space limit since the unit portions are not adjacent to each other during this winding which represents an easy assembly impossible to obtain for a crown already mounted in the stator for which the space left between two winding elements is very small. The invention also relates to an electromagnetic machine having at least one stator carrying a series of coils and at least one rotor carrying at least one magnet, characterized in that the at least one stator is a stator as previously described. This machine can take various forms as motor, generator or electromagnetic actuator.

    The figures are given by way of examples and are not limiting of the invention. They constitute schematic representations of principle intended to facilitate the understanding of the invention and are not necessarily at the scale of practical applications. In particular, the dimensions of the different pieces are not representative of reality.
    In what follows, reference is made to all the figures taken in combination. When reference is made to one or more specific figures, these figures are to be taken in combination with the other figures for the recognition of the designated reference numerals.
    For simplicity, when in a figure there are several elements of the same type such as unitary portions, mortises and tenons, notches, etc ..., it is referenced only one element per type for simplification and clarity figures.
    Referring to all the figures, the present invention relates to a stator for an axial flow electromagnetic machine. The stator forming a ring 1 having two circular faces 1a, 1b. These circular faces 1a, 1b are connected by a thickness or slice of the ring 1. The circular face 1a of the ring 1 may be the face of the ring vis-à-vis the rotor thus forming part of the air gap the electric machine comprising the stator.
    The ring 1 has an internal cavity 2 delimited by an inner periphery while the periphery of the ring is delimited by an outer periphery of the ring 1.
    The stator comprises windings 3 regularly distributed in the ring 1. According to the invention, each unit portion 4 has a core 5 around which a winding 3 is wound, the unitary portions 4 forming at least partially the ring 1 being arranged, some by compared to others concentrically. A unitary winding portion 4 is shown at a distance from the ring 1 of the stator in FIGS. 1, 2 and 6. The set of unit winding portions 4 at least partially forming the ring 1 of the stator with the unitary portions 4 arranged adjacent to them. to each other concentrically at the center of the ring 1. The unitary portions 4 each have securing means 8 to 12 either with a support member 6 which may or may not be part of a housing housing the ring gear 1, or with means for interlocking 8 to 12 between directly adjacent unit portions 4 fixed directly to the housing.
    The elementary windings 3 carried by the unit portions 4 after assembly by forming the stator ring can be interconnected to form windings.
    The unitary portions 4 forming the ring 1 of the stator can be made with laminated sheets or based on magnetic or nonmagnetic materials.
    A housing, not shown in the figures can accommodate the ring 1. In this case, the support member 6, if it is present, may be part of the housing or the support member 6 may be an integral insert of the casing. The support member may be integral with the protective housing or may be an insert of the same material or different material relative to the housing.
    Between two cores 5 of adjacent unit portions 4 there remains a free space forming a notch 13 and, if appropriate, an isthmus 13a formed by the edges 4a located on the side intended to form an air gap on a first circular face 1a of the ring 1 .
    The edges 4b of each unit portion 4 of a second face 1b of the ring 1 opposite to the first circular face 1a together with side projecting portions 4c of each unit portion 4 may delimit a yoke 14, the adjacent unit portions 4 being arranged end to end by their edges 4b and their parts in lateral projection 4c. It is this face 1b of the ring 1 intended to be opposite to the gap which can carry a support member 6.
    The laterally projecting portions 4c of two adjacent unitary portions 4 may define, with the end portions near the edges 4b of the unitary portions, a receiving space for a fastening element carried by a support member 6, advantageously a cleat 9.
    The securing means 8 to 12 may be removable or permanent. In the first case, the securing means 8 to 12 removable can be performed by screwing elements, connecting elements or snap between adjacent unit portions 4. For example, the securing means 8 to 12 removable can be performed by screwing elements, connection or snap on the edges 4b vis-à-vis and arranged end to end unitary portions 4 adjacent.
    In the second case, the securing means 8 to 12 permanent can be performed by welding, gluing or by rivet type elements. For example, the securing means 8 to 12 permanent can be performed by welding, gluing or riveting the edges 4b vis-à-vis and arranged end to end unitary portions 4 adjacent. The welding or gluing can be done by points or by cord.
    For example, the adjacent unitary portions 4 may be welded at the inner and outer peripheries of the ring 1 in order to improve the mechanical strength, this as an alternative or in addition to detachable connection means, the internal periphery delimiting the internal cavity 2 of the crown 1.
    The dimensions of a support member 6 may be adapted to those of the associated circular face 1b. For example, the support member 6 may be of circular configuration being of a diameter a little larger than the ring 1 and being concentric with the ring 1. The support member 6 may have radial apertures 8 to the 1 and positioned in alignment with the edges 4b of the adjacent unit portions 4. The support member 6 may have securing forms 9,10 associated with complementary shapes 11, 12 of the adjacent unit portions 4.
    As shown in FIG. 5, the passages 8 may be in the form of radial slots at the ring 1 and positioned in alignment with a respective notch 13 between coils 3 of adjacent unit portions 4, at this figure above each notch 13, this at least during the welding operation. It should be noted that this can also be valid for a gluing operation. The notch 13 can be closed, in which case the edges 4b of the adjacent unit portions 4 partially delimiting the notch 13 are directly in contact. The notch 13 may also be semi-closed in which case a space remains between the edges 4b of the adjacent unit portions 4 delimiting one side of the notch 13, as shown in FIG. 4.
    The cords or points of welding are advantageously on the edges 4b of the unit portions 4 glued against each other so being aligned with the middle of the notch 13 respectively between two adjacent unit portions 4.
    In Figures 3 and 4, it is not used support member. Bonding by welding or bonding can be done by points or weld seam or bonding on edges 4b vis-à-vis applied against each other of the two adjacent unit portions 4. This can be advantageously on a face 1b of the two circular faces 1a, 1b of the ring 1 or on both sides 1a, 1b. In Figure 5, there is used a support member 6 for one of the circular faces. Bonding by welding or bonding can be done by points or weld seam or bonding on edges 4b vis-à-vis applied against each other of two adjacent unit portions 4, edges 4b being accessible from the outside of the ring 1 through the lights 8 when a support member 6 is provided.
    Alternatively, a circular face 1b having no support member of the two circular faces 1a, 1b of the ring 1 may have the edges 4b abutting of two adjacent unit portions 4 welded or glued against each other.
    Finally, it is also possible not to use a support member 6. In this case, it is the unitary portions 4 which are secured together, either permanently, for example by gluing or welding, or removably by connecting elements, screws or technical equivalents.
    In the embodiment shown in FIGS. 1 and 2, the forms of fastening 9,10 carried by the support member 6 can be insertion cleats 9. Each insertion cleat 9 can be of semicylindrical shape to triangular section constant over the length of the cleat.
    A vertex of the triangular section can point towards the support member 6 being fixed on this support member 6. Each of the other two vertices of the triangular section can be housed in a respective groove 12 carried an edge 4b vis-à-vis -vis of each of the two adjacent unit portions 4 flanking the cleat 9.
    In the embodiment shown in FIG. 6, the fastening forms 9, 10 carried by the support member 6 may be radial lights to the ring 1 passing right through the support member 6 forming mortises. 10.
    Each face of the unit portions 4 vis-à-vis the support member may then have a pin 11 penetrating into a respective mortise 10 in the mounted position of the adjacent unit portions 4 on the crown 1. It is possible that in addition, each pin 11 and the associated mortise 10 are welded together.
    For these two embodiments, it is possible to secure the unit portions 4 to each other on the circular face 1a, 1b opposite to that carrying the forms of attachment 9, 10. It is even possible to provide a support member 6 for this opposite circular face 1a, 1b. This is not shown in Figures 1, 2 and 6.
    It should be borne in mind that all previously detailed embodiments can be combined with each other, two support members, a single support member 6, or no support members 6 that can be used.
    In some embodiments, when a yoke 14 is present, an outer ring 7 can surround the yoke 14 of the ring 1 over its entire periphery, which allows a radial auxiliary holding of the unit portions 4 secured to the ring 1 according to the different embodiments.
    The present invention also relates to an electromagnetic machine having at least one stator carrying a series of coils 3 and at least one rotor carrying at least one magnet, characterized in that said at least one stator is a stator as previously described.
    By axial flow machine is meant all kinds of motors, generators or axial flow electromagnetic actuators. This machine can be both mono-gap or poly-air gaps by having one or more stators and one or more rotors can be superimposed relative to each other being separated by at least one gap on the same shaft. In a poly-air-electric machine, it is preferred not to use a support member as the two circular faces 1a and 16b are part of a respective air gap.
    For the same ring 1, the unit portions 4 may be of variable shape and size, for example twice as large or have different profiles.
    The present invention also relates to a method of manufacturing such a stator or such an electromagnetic machine. In this process, it is carried out the winding of a coil 3 on a core 5 forming a unit portion 4 dissociated from the other unit portions 4. This can be done separately for each unit portion 4 then dissociated from the other unit portions 4.
    This can be done in another position than the stator mounting station and not necessarily directly before mounting the stator. The unitary portions 4 and individually assembled can be stored as such and for example stored until they are mounted to form the crown 1 of the stator.
    It is then carried out the joining of the unit portions 4 between them and / or at least to a support member 6 to form the crown 1 of the stator.
    The solutions proposed by the present invention are well suited for producing a stator with semi-closed cores or teeth and can be applied in the case of open notches. The nuclei can be of variable size. The invention is in no way limited to the described and illustrated embodiments which have been given by way of example only.
