の電動車の駆動装置。[Claims for Utility Model Registration] (1) An accelerator that is connected between a predetermined VCC power source and a ground line and outputs an accelerator signal corresponding to the amount of operation, and control based on the value of the accelerator signal output from this accelerator. a control signal forming means for forming a signal; a switching means for turning on and off by being energized by the control signal output from the control signal forming means, and for intermittent energization to the motor;
A temperature sensor circuit detects the temperature accompanying the energization of the switching means and outputs a corresponding detection signal, and the switching means is forcibly activated when the value of the detection signal from this temperature sensor circuit exceeds a set value. In a drive device for an electric vehicle having a motor protection circuit that turns off the motor, one end of the temperature sensor circuit is connected to a predetermined VCC power supply, the other end of the temperature sensor circuit is connected to one end of an additional line, and the temperature sensor circuit is connected to one end of the additional line. A drive device for an electric vehicle, characterized in that the other end of the additional line is connected to a connection point between the accelerator and the ground line. (2) The driving device for an electric vehicle according to claim 1, wherein the switching means is mainly composed of a semiconductor element such as a transistor.
