In this paper. a novel fault diagnosis method for variable frequency drive (VFD)-fed induction motors is proposed using Wavelet Packet Decomposition (WPD) and greedy-gradient max-cut (GGMC) learning algorithm. The proposed method is developed using experimental stator current data in the lab for two 0. 25 HP induction motors fed by a VFD. https://www.spidertattooz.com/Zenith-El-Primero-36-000-VpH-03-2150-400/
