TLDR
In this article, wavelet packet decomposition of stator current was used for fault detection and diagnosis in induction motor mechanical faults. But this method can be extended to other fault detection applications.Abstract:
New feature coefficients for induction motor mechanical faults are obtained by wavelet packet decomposition of the stator current. The feature coefficients differentiate the healthy and faulty conditions with obvious difference and can be used for the purpose of stator current based fault detection and diagnosis. This method can be extended to other fault detection applications.read more

Noninvasive detection of broken rotor bars in operating induction motors
TL;DR: In this paper, a computer-based noninvasive broken bar fault detector for squirrel-cage rotors of induction motors is presented, which can be applied to existing motors without disassembly or shutdown and has the sensitivity to diagnose the presence of a single broken bar or an open end ring.
