Abstract :
Motor current signature analysis has been successfully used in induction machines for fault diagnosis. The method however does not always achieve good results when the load torque is not constant. This paper proposes a new approach to motor fault detection, by wavelet decomposition analysis. Theoretical development and experimental results are presented to support the research.
