摘要

A motor control device has a drive circuit that drives an electric motor with a battery as a power supply, a switch element that is provided between the battery and the drive circuit, the switch element supplying a current from the battery to the drive circuit when being turned on, the switch element cutting off the current from the battery to the drive circuit when being turned off, a rotation speed detector that detects a rotation speed of the electric motor, and a controller that operates the drive circuit to control the electric motor. The controller turns on the switch element when the rotation speed of the electric motor, which is detected by the rotation speed detector, is greater than or equal to a first predetermined value during stopping of the control of the electric motor.
