发明名称 Rotary electric machine and electric vehicle
摘要 A rotary electric machine includes a stator (230) having stator windings (238; 338); and a rotor (250) rotatably disposed in the stator (230), said rotor (250) having a rotor core (252) provided with a plurality of magnets (254) and a plurality of magnetic auxiliary salient poles (259) formed between poles of the magnets (254). In this rotary electric machine: a magnetic air gap (258) is provided in an axial direction of the rotor (250) in a position shifted in a circumferential direction from a q axis passing through a center of the magnetic auxiliary salient pole (259) within the magnetic auxiliary salient pole (259); and an amount of shifting the magnetic air gap (258) from the q axis in the circumferential direction differs according to a position of the magnetic air gap (257) in the axial direction so as to cancel torque pulsation in energization caused due to the magnetic air gap (258).
