A control device configured with a torque/current computation section, an actual current computation section, a current feedback control section, and a voltage control section. A two-axis rotating coordinate system has a first axis defined in a direction of field magnetic flux of a magnet provided in the rotor, and a second axis defined in a direction that is shifted by an electrical angle of 90 degrees with respect to the first axis. In the case where a torque command includes periodic torque vibration, the torque/current computation section executes first-axis command fixation control in which a first-axis current command, which is a first-axis component of the two-phase current command, is fixed at a predetermined value and a second-axis current command, which is a second-axis component of the two-phase current command, is vibrated in accordance with the torque vibration. |
