A frequency-based approach to detect bearing faults in induction motors using discrete wavelet transform

Detection of faults in induction motors is nowadays is a hot trend in the field of electrical machinery. There are several methods to detect electrical and mechanical faults in an asynchronous motor; fast Fourier transform, short-time Fourier transform, and wavelet transform are the most popular ones. A major deficiency that most of these solutions face is… CONTINUE READING
