  • Patent number: 11777356
    Abstract: A rotating electric machine includes a stator and a rotor. The stator includes a stator core that has a plurality of slots that are arranged in a circumferential direction and a stator winding that has a plurality of phase coils that are wound in the slots. The rotor is arranged so as to oppose the stator in a radial direction and has a plurality of magnetic poles in the circumferential direction. In the rotating electric machine, each of the phase coils has a plurality of series-connection coil groups that each includes n unit coils that are arranged to be wound in the circumferential direction. In each of the series-connection coil groups, a first end thereof is connected to a phase terminal for a respective phase and a second end is connected to a neutral point, and the series-connection coil groups are connected in parallel.
