摘要 |
A motor control unit designed to drive a motor in a PWM mode and control motor current by feedback is capable of reducing a fluctuation in the output torque of the motor caused by the switching among a plurality of motor driving modes or a change in the duty value of the motor PWM drive. The motor control unit has a switching device driving circuit (15) for driving the motor in the PWM mode and a plurality of motor driving modes for the driving control system of a motor, Q/D switching means (14) for switching the motor driving mode, and detected current correcting means (16) for correcting at least one input signal of input signal comparing means provided in a feedback control loop in accordance with the motor driving mode. When the motor driving mode is switched, the correction value given by the detected current correcting means is changed. <IMAGE> |
