Abstract
This study proposes a sensorless diagnostic approach for stator turn open fault (STOF) in permanent magnet synchronous motors (PMSMs) using zero-sequence voltage (ZSV) analysis and phase difference evaluation. A fundamental frequency component in ZSV enables fault detection, while phase difference deviations identify the faulty phase and assess severity. The proposed method allows early STOF detection without mechanical sensors, providing a cost-effective solution for predictive maintenance. Experimental validation confirms its effectiveness in improving reliability and lowering maintenance costs for PMSMs.
