Abstract:
In order to shorten an activation time while realizing high accuracy motor control, a motor control apparatus operable to control a motor is provided. The apparatus comprises: a first drive control unit configured to drive the motor by forced commutation control; a second drive control unit configured to drive the motor by vector control; and a control unit configured to control to drive the motor by one of the first drive control unit and the second drive control unit. A first control period which is a control period in which the first drive control unit controls the motor is shorter than a second control period which is a control period in which the second drive control unit controls the motor.
