Abstract
A motor control device according to the disclosure includes: a current control part, performing current control for rotating a motor from a stop state; a rotation speed calculation part, calculating an actual rotation speed of the motor; an acquisition part, acquiring a target rotation speed of the motor; a speed control part, performing speed control of the motor, so that the actual rotation speed of the motor becomes the target rotation speed; and a correction part, at a time when a current control state is transitioned to a speed control, correcting the target rotation speed based on a relation between the actual rotation speed and the target rotation speed. When the target rotation speed is corrected, the speed control part performs the speed control so that the actual rotation speed becomes the target rotation speed corrected by the correction part.
