Popis: Statistically, the outer race of the rolling-element bearing is the most sensitive element used in induction motors. Among the known diagnosis methods, the analysis of the stator current envelope based on its demodulation, makes it possible to directly obtain the signature of the searched faults without the fundamental effect. This paper discusses one of these methods known as the Wavelet-Kurtogram. For this purpose, a comparison between the Wavelet-Kurtogram and the Power Spectral Density using the Periodogram is carried out for bearing faults diagnosis. The experimental results obtained show the superiority and the effectiveness of Wavelet-Kurtogram in the detection of the outer race fault.
