  • Publication number: 20120274169
    Abstract: A rotating electric machine includes a stator and a rotor. Each of magnetic poles of the rotor includes a magnet insertion hole, a permanent magnet that is inserted in the magnet insertion hole, and a nonmagnetic portion formed between the permanent magnet and an auxiliary salient pole. A portion of the rotor core located toward the stator relative to the nonmagnetic portion function as a bridge portion connecting a magnetic pole peace with the auxiliary salient pole. A side of the nonmagnetic portion located toward the stator includes a first side at the bridge portion, extending along a virtual circular arc passing through the permanent magnet insertion hole closest to the stator, and a side of the nonmagnetic portion located toward the auxiliary salient pole includes a second side extending away from the stator, with the first side and the second side connected through a curved line.

  • Publication number: 20100270094
    Abstract: A rotating electric machine for driving a vehicle includes: a stator that comprises a stator core in which a plurality of slots extending in a direction of a rotation axis are arranged circumferentially and a stator coil inserted into the slots; and a rotor that is rotatably provided in the stator through a gap, wherein: the stator coil is constituted with conducting wires, and a cross section of a protruding portion of each of the conducting wires that protrudes from the slots in a coil end portion of the stator coil is formed into a substantially trapezoidal shape.
