  • Patent number: 9577480
    Abstract: A rotor includes a plurality of salient poles, each of which is formed by a plurality of plate members including steel plates that are stacked together, provided extending in a radial direction and around which a coil is wound. The plurality of salient poles has auxiliary salient poles that protrude from the salient poles between two salient poles that are adjacent to one another.

  • Patent number: 9124159
    Abstract: A stator that includes stator windings wound around teeth. A rotor includes: a rotor core; rotor windings wound around main salient poles of the rotor; and a diode serving as a magnetic characteristic adjustment portion that causes magnetic characteristics produced on the main salient poles by electromotive forces induced in the rotor windings to differ in the circumferential direction of the rotor. The rotor has auxiliary salient poles that are each protruded from a side surface of each main salient pole in the circumferential direction. In each of rotor slots formed between the main salient poles adjacent to each other in the circumferential direction, the auxiliary salient poles adjacent to each other in the circumferential direction are connected to each other within the rotor slot. In each rotor slot, at least a portion of the rotor windings is disposed radially inside the auxiliary salient poles.

  • Publication number: 20150194855
    Abstract: A rotor of a rotary electric machine includes a rotor core having a plurality of rotor salient poles disposed on an outer periphery of the rotor core in a circumferential direction of the rotor core, rotor coils wound on the rotor salient poles, and a retainer member provided to close a slot formed between the rotor salient poles. The retainer member includes a leg portion extending radially in the slot between rotor coils wound on two rotor salient poles adjacent to each other in the circumferential direction and fixed to the rotor core, and beam portions extending in the opposite circumferential directions each other from a radially outer end portion of the leg portion and that close an outer periphery of the slot. The leg portion of the retainer member is provided with protrusion portions protruded in circumferential directions to engage with the coil winding that forms the rotor coils.

  • Publication number: 20120256510
    Abstract: A rotary electric machine includes a stator that creates a rotating magnetic field, and a rotor around which a rotor winding is wound so that induced electromotive force is created by a harmonic component of the rotating magnetic field, and in which a magnetic pole is created through the induced electromotive force. The stator has an auxiliary pole that is a leading portion that leads the harmonic component from the stator to the rotor.

  • Publication number: 20110232980
    Abstract: A control device of a hybrid vehicle, configured with an engine; a motor that rotates together with the engine at least during traveling by using a driving force of the engine, and a speed change mechanism that shifts rotation of the engine and the motor to transmit the shifted rotation to a driving wheel. A zero torque control unit controls output torque of the motor to zero torque when a rotational speed of the motor reaches a predetermined rotation speed or more by driving rotation of the engine, and a motor temperature detection unit that detects a temperature of the motor. A motor protection control units that reduces a rotational speed of the engine when the temperature of the motor reaches an upper threshold value or more while the motor is being rotated at the predetermined rotational speed or more by the driving rotation of the engine.
