The rotary electric machine includes a stator having a stator winding and a rotor rotatably provided about a predetermined rotational axis with respect to the stator. The rotor includes a plurality of magnets, a plurality of magnetic auxiliary protrusions formed between the poles of the adjacent magnets, and a rotation shaft at a position shifted in the circumferential direction of the rotation axis from the q axis within the magnetic auxiliary protrusions and passing through the center of the protrusions. It has a magnetoresistive change portion installed along the axial direction of. The shift amount from the q-axis of the magnetoresistance change portion varies depending on the position of the magnetic auxiliary salient pole portion so that the torque pulsation during energization cancels each other. |
