Effects of Power Supply Phase Imbalance on the Electrical and Mechanical Performance of Induction Motor

This paper provides a comprehensive analysis of the electrical and mechanical behavior of induction motors under unbalanced fault conditions. We propose a novel detection method that utilizes the Hilbert-Huang spectral envelope of the stator current to identify and localize the unbalance faults. The results demonstrate the efficacy of this fault detection and localization approach, highlighting its ability to effectively address the various operational degradations of induction motors caused by this related fault.
