The invention relates to the field of fault diagnosis, in particular to a motor fault diagnosis method and system.
In the process of the continuous development of modern industrial production equipment in the direction of structure, automation and intelligence, the motor, as the most important power and drive device, has been widely used in high-speed trains, subways and intercity rail transit equipment. However, in production practice, the motor will inevitably fail due to long-term operation in a harsh environment. In the early stage of the fault, the fault characteristics are weak and the impact on the system operation is small, but if the measures are not taken in time, it may lead to the rapid deterioration and spread of the early fault, seriously affecting the performance of the motor and system safety.
Therefore, how to improve the accuracy of early fault diagnosis has become an urgent problem to be solved.
