路。[Claims for Utility Model Registration] A current limiter that connects a resistor to the power terminal side of a circuit consisting of a power transistor that supplies drive current to motor windings, and limits the drive current based on the voltage drop across this resistor. In a motor drive circuit in which the element is connected to the ground terminal side, the collector and emitter of a switching transistor are connected to both ends of the resistor, and the base of the switching transistor is connected to the base of the switching transistor so that the transistor is turned on when the motor is being driven and turned on when the motor is stopped. A motor drive circuit consisting of connected circuit means for applying a control signal to turn off the motor.
