摘要：
This paper deals with the mixed eccentricity fault detection in the closed loop of the induction motor driven by Field-Oriented Control. In this paper, in order to analysis, the unbalanced signals caused by the fault, two techniques are used for stator and quadratic currents component, such as FFT and wavelet transform. The result obtained by wavelet is more suitable for emergency signal analysis. This method is effective for stationary signal processing as well as non-stationary signal processing. Wavelet analysis was introduced to overcome the shortcomings of Fourier analysis.
