Motor fault diagnosing and processing method

Abstract

The invention provides a motor fault diagnosing and processing method. The method includes: when a motor is powered to start, collecting the starting parameter of the motor; reporting the starting parameter as a first fault parameter when the fact that the starting parameter is not in a preset starting threshold range is judged, and stopping motor starting; starting a vehicle when the fact that the starting parameter is in the preset threshold range, and collecting the work parameter of the motor during vehicle traveling; judging whether the work parameter of the motor is in a preset work threshold range or not, if so, allowing the vehicle to travel, and if not, reporting the work parameter as a second fault parameter; judging whether the reporting times of the second fault parameter is not less than preset times or not, if so, stopping the vehicle, and if not, recovering the second fault parameter of the motor until the second fault parameter is located in the preset work parameter threshold range. By the motor fault diagnosing and processing method, the problem that large potential safety hazard exists during motor use due to the fact that the work states of the motor cannot be timely acquired in the prior art is solved.

Description

technical field [0001] The invention relates to a motor fault and processing technology, in particular to a motor fault diagnosis and processing method of an electric vehicle. Background technique [0002] Electric vehicles have been widely concerned for their advantages of low energy consumption and zero pollution. As the key components of electric vehicles to provide power, electric motors play a very important role in the normal operation of electric vehicles. Therefore, an effective motor fault diagnosis system It is the key to ensure the safe and reliable operation of the motor. [0003] At present, the fault diagnosis of the motor is to detect the motor through a certain measuring device, obtain a certain parameter of the AC motor, and judge the fault of the motor by analyzing the detected parameters and carry out corresponding treatment, but the current fault detection is often in the The motor has been faulty or the motor is tested regularly, so that the user cannot...
