Abstract
A motor control device controls a drive of a motor having a coil, and includes a drive circuit and a control unit. The drive circuit has a plurality of switching elements, and switches the energization of the coil. The control unit includes an energization control part and a current limit part. The energization control part accelerates and then decelerates the motor, and controls energization of the coil so that a rotation position of the motor stops at a target rotation position. The current limit part limits the current during a deceleration control.
