Broken rotor bar detection of single phase induction motor using Wigner-Ville Distributions

Abstract

Fault diagnosis is vital for any type of machine employed in the industry for its superior operation. For this purpose condition monitoring of machinery is necessary to diagnose the different kind of faults in the machines for the smooth operation. In this research work, we have brought into consideration broken rotor bar losses and have analyzed them with various signal processing techniques through an online process and we analyze the diagnosis and severity of various faults using the details of these signal processing techniques. We are using the variants of WVD (Wigner-Ville Distribution) and then doing a comparison with STFT to demonstrate how these variants are more accurate in analyzing the rotor bar faults.
