Research of Fault Diagnosis Method of Asynchronous Motor

Abstract

The paper introduced principles of fault diagnosis method based on Park vector transformation, spectrum analysis of stator current based on Fourier transformation and the method based on wavelet transformation, and analyzed and discussed application effects of the three methods in fault diagnosis of three-phase cage type asynchronous motor.
