ータの過回転を発音表示するように構成したことを特徴
とする電動車両における電動機の過回転表示装置。Rotation speed detection that outputs a voltage corresponding to the rotation speed of the electric motor of the electric vehicle in an electric vehicle equipped with a high-speed travel warning device that connects the sounding body to the power source via a switch when the vehicle is traveling at a high speed that exceeds the driving speed. a comparison circuit that compares the output of the detection circuit with a reference voltage and generates an output when the rotational speed reaches an abnormally high rotational speed; and a comparison circuit that is driven by the output of the comparison circuit and connected in parallel to the switch. What is claimed is: 1. An overspeed display device for an electric motor in an electric vehicle, characterized in that a relay drive circuit is provided to close other switches that are connected to each other, and the overspeed of the motor is audibly displayed.
