FIG. 1 shows an outline of an internal configuration viewed from a direction orthogonal to the rotating shaft 22, FIG. 2 is a perspective view showing a part of the configuration of the stator and the rotor, and FIG. 3 shows a part of the configuration of the stator and the rotor. FIG. 4 shows a part of the configuration of the stator and the rotor as viewed from the direction parallel to the rotation shaft 22, and FIGS. 5 and 6 show a part of the configuration of the rotor as viewed from the direction parallel to the rotation shaft 22. Indicates. However, the configuration of the portion not shown in FIGS. 2 to 6 is the same configuration as the illustrated portion. The toroidal winding type electric rotating machine 10 according to the present embodiment includes a stator 12 fixed to a casing 11 and a rotor that is disposed to face the stator 12 and is rotatable with respect to the stator 12. The rotor includes a radial rotor 14 disposed opposite to the stator 12 in a radial direction (hereinafter simply referred to as a radial direction) orthogonal to the rotor rotation axis (rotation axis 22), and a direction parallel to the rotor rotation axis (rotation axis 22). (Hereinafter, referred to as a rotation axis direction) and an axial rotor 64 that is disposed to face the stator 12 and rotates together with the radial rotor 14. In the example shown in FIGS. 1 to 6, the radial rotor 14 is disposed on the radially inner side of the stator 12, and faces the inner peripheral surface (radial surface) of the stator 12 with a predetermined gap. Two axial rotors 64 are arranged on the outer side in the rotation axis direction of the stator 12 with the stator 12 interposed therebetween, and are opposed to both side surfaces (axial surfaces) of the stator 12 with a predetermined gap.

  The stator 12 includes an annular core portion 26 and a plurality of (for example, three-phase) coils 28u, 28v, and 28w that are toroidally wound around the annular core portion 26. In the stator 12, a plurality of radial teeth 30 protruding from the inner peripheral surface of the annular core portion 26 in the radial direction (inward in the radial direction) toward the radial rotor 14 are arranged at intervals along the stator circumferential direction. A slot 31 is formed between the radial teeth 30. Further, the stator 12 has a plurality of axial teeth 80 projecting from the both side surfaces of the annular core portion 26 toward the axial rotor 64 in the rotation axis direction (outward in the rotation axis direction) with an interval along the circumferential direction of the stator. A slot 81 is formed between the axial teeth 80. 1-4, the coils 28u, 28v, 28w are distributedly wound through the slots 31, 81. The annular core portion 26, the radial teeth 30 and the axial teeth 80, that is, the iron core portion of the stator 12, for example, was coated with a film that does not conduct electricity on the surface of ferromagnetic fine particles such as iron. It can be formed of a three-dimensional isotropic magnetic material such as a dust core material obtained by compacting powder.

  The radial rotor 14 includes a substantially cylindrical radial core 16 and a plurality of permanent magnets 18 disposed on the outer peripheral portion of the radial core 16 so as to face the stator 12 (radial teeth 30) in the radial direction. In the example shown in FIGS. 2 to 5, the magnetic pole is formed by a permanent magnet 18 embedded in a V shape in the radial core 16, the magnetization direction of the permanent magnet 18 is inclined with respect to the radial direction, and the rotational axis direction. It is the direction perpendicular to. A plurality of V-shaped permanent magnets 18 are arranged so that their magnetic poles alternate in the circumferential direction (rotation direction) of radial rotor 14 ("N pole" and "S pole" are alternately arranged), that is, adjacent permanent magnets. The magnets 18 are arranged so that the magnetization directions are reversed, and are arranged at intervals along the circumferential direction of the radial rotor 14. Therefore, the radial core 16 portion (magnetic body) is also disposed on the surface of the permanent magnet 18 (radially outside of the permanent magnet 18), and between the V-shaped permanent magnets 18 adjacent in the circumferential direction. Is also provided. Thereby, in the radial rotor 14, the magnetic resistance when the magnetic flux from the stator 12 (radial teeth 30) passes changes according to the rotation direction. However, the arrangement of the permanent magnets 18 is not limited to this example. For example, the permanent magnets 18 may be exposed on the surface of the radial rotor 14 (the outer peripheral surface of the radial core 16). The magnetic direction may coincide with the radial direction. Also, by providing a slit or a non-magnetic material in the radial core 16, the magnetic resistance when the magnetic flux from the stator 12 passes can be changed according to the rotation direction. Further, the radial core 16 can be configured by laminating thin silicon steel plates (electromagnetic steel plates) in the rotation axis direction, or can be formed by a dust core material.

  Each axial rotor 64 includes an annular axial core 66 and a plurality of permanent magnets 68 disposed on the side surface of the axial core 66 so as to face the stator 12 (axial teeth 80) in the rotation axis direction. In the example shown in FIGS. 1 to 3 and 6, the magnetic pole is formed by the permanent magnet 68 exposed on the surface of the axial rotor 64 (side surface of the axial core 66), and the magnetization direction of the permanent magnet 68 coincides with the rotation axis direction. Direction. The plurality of permanent magnets 68 are arranged such that the magnetic poles alternate in the circumferential direction (rotation direction) of the axial rotor 64 ("N pole" and "S pole" are alternately arranged), that is, between the adjacent permanent magnets 68. It arrange | positions so that the magnetization direction may be reversed and it arranges at intervals along the circumferential direction of the axial rotor 64. Further, salient poles 69 projecting toward the stator 12 (axial teeth 80) are formed between the permanent magnets 68 adjacent in the circumferential direction. Thereby, in the axial rotor 64, the magnetic resistance when the magnetic flux from the stator 12 (axial tooth 80) passes changes according to the rotation direction. However, the arrangement of the permanent magnets 68 is not limited to this example. For example, the permanent magnets 68 may be embedded in the V-shape in the axial core 66 like the permanent magnets 18. The magnetization direction may be inclined with respect to the rotation axis direction and perpendicular to the radial direction. Further, by providing a slit or a non-magnetic material in the axial core 66, the magnetic resistance when the magnetic flux from the stator 12 passes can be changed according to the rotation direction. Further, the axial core 66 can be constituted by a wound iron core, can be constituted by laminating electromagnetic steel plates in the radial direction, or can be formed by a dust core material.

  The radial rotor 14 is mechanically connected to the rotary shaft 22, and each axial rotor 64 is mechanically connected to the rotary shaft 22 via the disk-like member 23. That is, the radial rotor 14 and each axial rotor 64 are mechanically connected via the rotating shaft 22 and the disk-shaped member 23, and rotate integrally. In this embodiment, the rotating shaft 22 and the disk-shaped member 23 are made of a nonmagnetic material such as aluminum or nonmagnetic stainless steel. That is, the nonmagnetic rotating shaft 22 and the nonmagnetic disc-like member 23 mechanically connect the radial rotor 14 (radial core 16) and the axial rotor 64 (axial core 66), but the radial rotor 14 (radial core 16). The magnetic connection between the core 16) and the axial rotor 64 (axial core 66) is cut off.

  Furthermore, in the present embodiment, as shown in FIG. 1, it faces the side surface of the radial rotor 14 (radial core 16) in the rotation axis direction and faces the inner peripheral surface of the axial rotor 64 (axial core 66) in the radial direction. A gap is formed at the position 25 where no magnetic material is disposed. However, a non-magnetic member (for example, a non-magnetic disk-like member 23) may be disposed at this position 25 instead of the gap.

  By passing a plurality of phases (three phases) of alternating current through the plurality of phases (three phases) coils 28u, 28v, 28w, for example, as shown in FIG. 7, the magnetic flux flows in the stator 12, and the radial teeth 30 and the axial teeth 80 are obtained. Are sequentially magnetized, and a rotating magnetic field rotating in the circumferential direction of the stator is formed in the radial teeth 30 and the axial teeth 80. The rotating magnetic field formed on the radial teeth 30 acts on the radial rotor 14 from the front end surface 30a, and the magnetic field (field magnetic flux) of the permanent magnet 18 of the radial rotor 14 interacts with the rotating magnetic field, thereby attracting and repelling. Occurs. Torque (magnet torque) can be applied to the radial rotor 14 by electromagnetic interaction (attraction and repulsion) between the rotating magnetic field of the radial teeth 30 and the field magnetic flux of the permanent magnet 18. Furthermore, the portion of the radial core 16 (magnetic body) disposed on the surface of the V-shaped permanent magnet 18 and the portion of the radial core 16 disposed between the permanent magnets 18 adjacent in the circumferential direction are salient poles. The reluctance torque can be obtained in addition to the magnet torque by being attracted to the rotating magnetic field of the radial teeth 30 so as to reduce the magnetic resistance of the radial rotor 14. When applying torque to the radial rotor 14, the tip surface 30 a (radial surface) of the radial teeth 30 functions as a torque generating surface for generating torque by applying a rotating magnetic field to the radial rotor 14. And the annular core part 26 functions as a yoke.

  Further, the rotating magnetic field formed on the axial teeth 80 acts on the axial rotor 64 from the tip surface 80a, and the magnetic field (field magnetic flux) of the permanent magnet 68 of the axial rotor 64 interacts with this rotating magnetic field to attract and Repulsive action occurs. Torque (magnet torque) can be applied to the axial rotor 64 by electromagnetic interaction (attraction and repulsion) between the rotating magnetic field of the axial teeth 80 and the field flux of the permanent magnet 68. Further, the salient pole 69 formed between the permanent magnets 68 adjacent in the circumferential direction is attracted to the rotating magnetic field of the axial teeth 80 so that the magnetic resistance of the axial rotor 64 is reduced, so that the reluctance torque is also converted into the magnet torque. In addition it can be obtained. When torque is applied to the axial rotor 64, the tip surface 80a (axial surface) of the axial teeth 80 functions as a torque generation surface for generating torque by applying a rotating magnetic field to the axial rotor 64.

  Therefore, the toroidal winding type electric rotating machine 10 according to the present embodiment is caused to function as an electric motor that generates power (mechanical power) in the radial rotor 14 and the axial rotor 64 using electric power supplied to the coils 28u, 28v, 28w. be able to. On the other hand, the toroidal winding type electric rotating machine 10 according to the present embodiment can be made to function as a generator that generates electric power in the coils 28u, 28v, 28w using the power of the radial rotor 14 and the axial rotor 64.

  Toroidal winding makes coil manufacture easier than distributed winding, but increases the number of coils that do not work effectively for the generation of torque of the rotor, and thus tends to increase physique and copper loss. In the present embodiment, not only the front end surface 30a (radial surface) of the radial teeth 30 but also the front end surface 80a (axial surface) of the axial teeth 80 can be used as a torque generation surface, whereby the torque generation area can be increased. As a result, it is possible to reduce the number of coils that do not work effectively to generate torque of the rotor (radial rotor 14 and axial rotor 64), and to increase the torque of the rotor while suppressing an increase in the size and an increase in copper loss.

  However, when the radial rotor 14 and the axial rotor 64 are magnetically connected when generating torque in the radial rotor 14 and the axial rotor 64, the magnetic flux flowing in the radial rotor 14 and the magnetic flux flowing in the axial rotor 64. Interfere with each other, a short-circuit magnetic flux is generated between the radial rotor 14 and the axial rotor 64, and the effective magnetic flux contributing to the torque of the radial rotor 14 and the axial rotor 64 is reduced. On the other hand, in the present embodiment, the rotary shaft 22 and the disk-like member 23 that mechanically connect the radial rotor 14 and the axial rotor 64 are made of nonmagnetic members, so that the radial rotor 14 and the axial rotor 64 The magnetic connection is broken. As a result, the magnetic flux flowing in the radial rotor 14 and the magnetic flux flowing in the axial rotor 64 can be prevented from interfering with each other, and the short-circuit magnetic flux between the radial rotor 14 and the axial rotor 64 can be suppressed. . Therefore, the effective magnetic flux contributing to the torque of the radial rotor 14 and the axial rotor 64 can be increased, and the efficiency of the toroidal winding type rotating electrical machine 10 can be improved.

  Further, in the present embodiment, the radial rotor 14 and the axial rotor 64 are provided by providing a gap or a nonmagnetic member at a position 25 facing the radial rotor 14 in the rotation axis direction and facing the axial rotor 64 in the radial direction. Can be further suppressed, and the effective magnetic flux to the torque of the radial rotor 14 and the axial rotor 64 can be further increased.

  In Patent Document 1, the direction of magnetization of the permanent magnet disposed on the rotor is the circumferential direction, and magnetization is appropriate for efficiently generating magnet torque for each of the radial gap portion and the axial gap portion. Since it is not the direction, it is difficult to efficiently generate torque in the rotor. Since the permanent magnets and magnetic members are alternately arranged in the circumferential direction on the rotor, the permanent magnets enter in series in the magnetic path in the rotor, increasing the magnetic resistance and generating magnetic flux. As a result, the reluctance torque is reduced. Furthermore, the strength of the rotor tends to decrease.

  On the other hand, in this embodiment, the radial rotor 14 and the axial rotor 64 are magnetically independent. Therefore, the magnetization direction of the permanent magnets 18 and 68 can be set in the direction in which the magnet torque is efficiently generated for each of the radial rotor 14 and the axial rotor 64, and the torque can be efficiently generated in the rotor. it can. Further, reluctance torque can be efficiently generated for each of the radial rotor 14 and the axial rotor 64. Further, by using a nonmagnetic material for the rotating shaft 22 and the disk-like member 23 that mechanically connect the radial rotor 14 and the axial rotor 64, it is easy to ensure the strength of the rotor. Further, since the radial rotor 14 and the axial rotor 64 are magnetically independent, when the radial core 16 and the axial core 66 are configured by stacking electromagnetic steel plates, the radial core 16 and the axial core 66 are electromagnetically coupled. It becomes easy to change the lamination direction of the steel plates (the radial core 16 is the rotation axis direction and the axial core 66 is the radial direction), and the radial core 16 and the axial core 66 are easily made of electromagnetic steel plates.

  In the above description of the embodiment, torque is generated in the radial rotor 14 and the axial rotor 64 using both magnet torque and reluctance torque. However, in the present embodiment, it is possible to generate torque in the radial rotor 14 using only the magnet torque without using the reluctance torque. Alternatively, torque can be generated in the radial rotor 14 using only the reluctance torque without using the magnet torque (omitting the permanent magnet 18). Similarly, torque can be generated in the axial rotor 64 using only the magnet torque without using the reluctance torque, or only the reluctance torque can be generated without using the magnet torque (omitting the permanent magnet 68). Torque can also be generated in the axial rotor 64 by using it.

  In the present embodiment, the stator 12 and the radial rotor 14 can also function as an induction machine. In that case, instead of the permanent magnet 18, a cage conductor or winding through which an induced current flows is arranged on the outer peripheral portion of the radial rotor 14 (radial core 16) in the radial direction so as to face the stator 12 (radial teeth 30). Set up. When the stator 12 and the radial rotor 14 function as an induction machine, the rotating magnetic field formed in the radial teeth 30 acts on the cage-shaped conductor (or winding) of the radial rotor 14, so that the cage-shaped conductor ( Or the magnetic field acting on the windings) fluctuates. An induced current is generated in the cage conductor (or winding) according to the fluctuation of the magnetic field. Torque acts on the radial rotor 14 by the induced current and the rotating magnetic field of the stator 12.

  Similarly, the stator 12 and the axial rotor 64 can also function as an induction machine. In that case, instead of the permanent magnet 68, a cage conductor or winding through which an induced current flows is arranged on the side surface of the axial rotor 64 (axial core 66) so as to face the stator 12 (axial teeth 80) in the rotation axis direction. Set up. When the stator 12 and the axial rotor 64 function as an induction machine, the rotating magnetic field formed in the axial teeth 80 acts on the cage-shaped conductor (or winding) of the axial rotor 64, so that the cage-shaped conductor ( Or the magnetic field acting on the windings) fluctuates. An induced current is generated in the cage conductor (or winding) according to the fluctuation of the magnetic field. Torque acts on the axial rotor 64 by the induced current and the rotating magnetic field of the stator 12.

  In the above description of the embodiment, it is assumed that the radial rotor 14 is disposed on the radially inner side of the stator 12. However, in the present embodiment, the radial rotor 14 may be disposed on the radially outer side of the stator 12.

  In the above description of the embodiment, it is assumed that the two axial rotors 64 are opposed to each other with the stator 12 interposed therebetween in the rotation axis direction. However, in the present embodiment, one axial rotor 64 can be opposed to the stator 12 in the rotation axis direction.

  In the above description of the embodiment, one radial rotor 14 and one stator 12 are arranged. However, in the present embodiment, a plurality of radial rotors 14 and stators 12 can be arranged.

  As mentioned above, although the form for implementing this invention was demonstrated, this invention is not limited to such embodiment at all, and it can implement with a various form in the range which does not deviate from the summary of this invention. Of course.
