PROBLEM TO BE SOLVED: To reduce a change in the output torque of a motor caused by the changeover of a plurality of motor driving modes and caused by a change in the duty value of the PWM drive of the motor in a motor control apparatus which PWM-drives the motor and which feedback-controls a motor current. SOLUTION: A motor control apparatus is provided with a switching-element drive circuit 15 which PWM-drives a motor, with a Q/W changeover means 14 which comprises a plurality of motor driving modes by the drive control system of the motor and which changes over the motor driving modes and with a detection-current correction means 16 by which at least one input signal of an input-signal comparison means 17 installed inside a feedback control loop is corrected according to the motor driving modes. When the motor driving modes are changed over, a correction value by the detection-current correction means 16 is changed over. |
