。 ゛[Claims for Utility Model Registration] A DC motor for driving a bogie is connected to a DC power source via a first switching element that is turned on and off in response to a pulsed speed control signal, and the speed control signal In an electric trolley drive circuit that can control the speed of a DC motor, the speed control signal waveform and the DC motor applied voltage waveform are compared, and the power is turned off when the correspondence between the two waveforms is no longer the same as when the DC motor is normally rotating. A comparison circuit outputs a signal, and a second switching element is turned off when a power OFF signal is output from this comparison circuit. An electric trolley drive circuit comprising: a cutoff circuit that cuts off between the DC motor and the DC power supply.゛
