Abstract:
A motor control apparatus includes a motor that rotates a controlled object, an encoder that outputs a pulse signal in synchronization with a rotation of the motor, and a control section that performs a feedback control so as to rotate the motor to the target rotational position. The control section includes a stopping and holding control portion. The stopping and holding control portion performs a stopping and holding process in which the stopping and holding control portion supplies electric current to the motor so as to stop and hold the motor for a current-supply holding time. The stopping and holding control portion sets the current-supply holding time on the basis of a rotation speed of the motor just before the stopping and holding process.
