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
