چکیده
In this paper the faults diagnosis of induction machines based on the discrete wavelet transform (DWT) is detailed. The wavelet decomposition is used to extract the information from a signal over a wide range of frequencies. This analysis is performed in both time and frequency domains. The Daubechies wavelet is selected for the analysis of the stator current. Wavelet components appear to be useful for detecting different electrical faults. In this paper we will study the problem of broken rotor bars, and end-ring segment. Keywords— Fault diagnosis, Induction Machines, broken endring, broken rotor bars, Wavelet transform, Decomposition level

متن کاملRotor Faults Detection in Induction Motor by Wavelet Analysis
ABSTRACT Motor current signature analysis has been successfully used for fault diagnosis in induction motors. However, this method does not always achieve good results when the speed or the load torque is not constant, because this cause variation on the motor slip and fast Fourier transform problems appear due to non-stationary signal. This paper experimentally describes the effects of rotor b...
