とを特徴とする直流分巻モータの制御装置。 In a control device for a DC shunt motor that includes a control circuit that controls both a chopper transistor that inputs DC voltage from a battery and a regeneration transistor, a short circuit detection circuit that detects a short circuit state of the regeneration transistor. and a rotation sensor that detects the rotational state of the motor, and a signal from a short-circuit detection circuit when the regeneration transistor is short-circuited to turn off the chopper transistor, reduce the field current to zero, and output after the motor rotation has stopped. A protection circuit that cuts off input from the battery to the chopper transistor in response to a signal from the rotation sensor;
A control device for a DC shunt motor, characterized in that an armature circuit and a control circuit are protected.
