Abstract:
1. A rotating electric machine for a vehicle, comprising: a stator; a rotor held rotatably inside said stator; wherein, said stator comprises a stator core and stator windings; said stator windings comprise three-phase windings which are wound on said stator core; said rotor comprises a rotor core and a plurality of permanent magnets embedded beneath the surface of said rotor core; a plurality of auxiliary magnetic pole areas are formed in said rotor core, and are disposed along a circumferential direction of said rotor core; said permanent magnets are arranged between said auxiliary magnetic pole areas, with permanent magnets which are located on circumferentially opposite sides of said auxiliary magnetic pole areas having different polarities; and a reluctance torque is generated at said auxiliary magnetic pole areas based on a magnetomotive force which is generated by three phase current flowing through said stator windings.
