摘要： A motor control device controls a motor driving mechanism which drives a motor according to a motor drive signal for providing a normal drive signal and a locked condition signal. When the motor becomes overloaded while being driven by the motor driving mechanism according to the motor drive signal, the motor driving mechanism is controlled by controlling circuitry which inhibits the motor drive signal from being supplied to the motor driving mechanism. The controlling circuitry, while the motor is in the overloaded state, controls the motor driving mechanism so that power is supplied intermittently to the motor, or so that the supply of power for the regular and reverse rotation is given alternately. The controlling circuitry, when the load of the motor becomes normal, allows driving of the motor according to the motor drive signal.
