摘要
A rotating electric machine is equipped with a consequent-pole type rotor that includes a magnetic pole having a permanent magnet buried therein and a soft magnetic material pole that interposes two magnetic poles. The thickness of the permanent magnet and a circumferential width of the soft magnetic material pole have a relationship that prevents a spread of magnetic flux distribution in the circumferential direction within a gap between the soft magnetic material pole and a stator. As a result, a magnetic flux density difference in the circumferential direction is prevented, which enables a reduction of cogging torque based on an effective reduction of low-frequency space order components that originate from components other than a main component.
