Abstract
A motor control device controls the drive of a motor including a motor winding. The motor control device is provided with an energization control unit and a standstill determination unit. The energization control unit controls the energization of the motor winding in accordance with a detection value of a rotational position sensor that detects a rotational position of the motor. The standstill determination unit determines a standstill of the motor. When a standstill of the motor is detected, the energization control unit controls energization in a change pattern that is an energization pattern different from a preset regular pattern in accordance with the detection value of the rotational position sensor.
