This paper presents the application or the Wigner-Ville distribution (WVD) to the spectral analysis of the voltage and current systems at the terminals of an inverter-fed induction motor. The spectral- leakage problem is studied and the attention is rocused on the effect of wlndowing. New suitable windows are proposed to provide high-resolution signal characterisation in the time-frequency space. The results show that the spectral analysis, based on the WVD in conjunction with suitable windows, may be used to determine the occurrence and severity of motor faults.
