Abstract

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 put into an on state, the switch element cutting off the current from the battery to the drive circuit when being put into an off state, a voltage detector that detects a voltage at the drive circuit, and a controller that operates the drive circuit to control the electric motor. The controller turns on the switch element when the voltage at the drive circuit, which is detected by the voltage detector, is greater than or equal to a first predetermined value during stopping of the control of the electric motor.
