In a case where a computing period of a torque ripple compensation section which computes current compensation values id and iq to be caused to flow into a motor in order to prevent occurrence of a torque ripple in the motor differs from a control period of a current control section which controls a feedback to the motor in such a way that current command values i*d and i*q additionally provided with the current compensation values id and iq flow into the motor, the microcomputer sets the current compensation values id and iq to zero when a rotor angular velocity Ére of the motor is equal to or greater than a first threshold value É 1 .
