Abstract
Motor current signature analysis has been successfully used for fault diagnosis in induction machines. However, thismethoddoes not always achieve good results with variable load torque. This paper proposes a different signal processing method, which combines wavelet and power spectral density techniques giving the power detail density as a fault factor. The method shows good theoretical and experimental results.
