This text book is valuable for those researchers and engineers who keen to do work in condition monitoring of Induction motor, driven by inverter. The book presents advanced Digital Signal Processing (DSP) transformative techniques application for fault diagnosis purpose in the induction motor . These DSP based transformative techniques are able to diagnose induction motor faults in steady state condition as well as in transient state condition by time domain, frequency domain and time-frequency domain. This book intends to give an overview of various faults state of induction motor and also its diagnostic techniques .
