  • Publication number: 20190165659
    Abstract: A rotary electric machine equipped with a magnetic flux variable mechanism includes a case body, a mover moving upon receipt of centrifugal force, a magnetic flux short circuit member, a cam member, and biasing springs. The cam member includes a cam surface so as to face the mover and make contact with the mover, and the cam member converts a radial movement of the mover received by the cam surface into an axial movement of the magnetic flux short circuit member. The biasing springs give a biasing force to the magnetic flux short circuit member in a direction distanced from an axial end surface of the rotor core, so as to determine a position of the magnetic flux short circuit member along the axial direction in a state where the biasing force is balanced with the centrifugal force applied to the mover via the cam member.

  • Patent number: 10116181
    Abstract: A slot insulating paper (12) is arranged in a slot (18) of a core (10) of an electric motor or generator. In a state where the slot insulating paper (12) is spread in a sheet shape, a region (high stiffness portion (36)) that is part of the slot insulating paper (12) is a breakage resistance portion having a higher resistance against breakage than the other region (ordinary portion (38)). The slot insulating paper (12) may be formed by laminating a plurality of insulating layers. In the breakage resistance portion, for example, at least one of the laminated insulating layers is a high stiffness layer formed of a high stiffness material. Thus, the breakage resistance portion is formed to have a high stiffness. With a high stiffness, it is possible to improve breakage resistance.

    Abstract: A flat wire (36) that forms a stator coil (16) has an insertion portion (22) that is inserted into a slot (14), and a coil end portion (30) that protrudes from an end portion of the stator coil (16). An insulating layer of an adjacent portion (38) that is adjacent to a flat wire (36) of a different phase at the coil end portion (30) is thicker than an insulating layer in another region. Setting the thickness of the insulating layer of each part according to the required insulation performance in this way makes it possible to make the overall insulating layer thinner, and improve the in-slot space factor of the stator coil while ensuring insulation performance.
