Abstract
A motor control device includes: an inverter circuit including a semiconductor switching element for drive which drives a motor; a cut-off circuit including a semiconductor switching element for cut-off which cuts off an electric connection between the motor and the inverter circuit; a failure detection unit; a rotation number detection unit; and a control unit. In a case where the failure detection unit detects a failure of the semiconductor switching element for drive, the control unit turns off the semiconductor switching element for drive, and in a case where the number of rotations of the motor which is detected by the rotation number detection unit is less than a predetermined first threshold, the control unit further turns off the semiconductor switching element for cut-off.
