Implementation of Electric Motor Current Noise Detecting and the Dynamic Spectrum Analysis

摘要：

In order to effectively diagnose electric motor working state, a new method of on-line detecting the motor current noise signal based on mutual inductance is put forward. The motor current/voltage change and electromagnetic noise information can be meanwhile detected by the method. The motor system dynamic model can be established by using the current noise signal, and the dynamic power spectrum of the motor working state can be describe according to the system model, which can diagnose the motor fault status.
