The invention provides a steering judging system and method of a motor train unit traction electric machine. The system comprises an inclinometer, a microcontroller and an upper computer, wherein the inclinometer is used for collecting the inclination angle of a coupling joint of the motor train unit traction electric machine; the microcontroller is connected with the inclinometer and is used for forming inclination angle sampling information according to the inclination angle obtained by sampling the inclinometer with a preset frequency and transferring the inclination angle sampling information to the upper computer; the upper computer receives the inclination angle sampling information and analyzes the inclination angle sampling information to obtain steering of the motor train unit traction motor. The invention also provides the steering judging method of the motor train unit traction motor corresponding to the steering judging system of the motor train unit traction electric machine. The system and the method can be used for achieving judging of steering of the motor fast and accurately, so that the traction motor steering judging testing cycle is shortened, the accuracy of steering judging of the motor is improved, and the automatic detection of steering judging of the motor train unit traction motor is achieved.
Description
technical field [0001] The invention belongs to the technical field of rail transit, and more specifically relates to a steering discrimination system and method for a traction motor of an EMU. Background technique [0002] According to the working principle of the motor, the rotation direction of the three-phase motor is related to its three-phase line sequence. When any two phases of the three-phase line sequence are connected, the motor will rotate in the opposite direction. A reverse-connected three-phase asynchronous motor is equivalent to a locked-rotor, and when the motor is locked-rotor, huge heat energy is generated in the three-phase winding, which causes the motor to burn out. [0003] At present, the steering of the EMU traction motor is still judged manually. When starting the test, the testers use manual methods to touch and observe one by one to judge the rotation direction of the motor. The work efficiency of this method is extremely low, and at least two t...
