Interturn Short Circuit Fault Mitigation in PMSMs
Lukas Zezula, Matus Kozovsky, Ludek Buchta, Petr Blaha
Interturn short circuits are among the most critical faults in permanent magnet synchronous motor drives, as they combine localized heating in the shorted stator phase with electrical asymmetry that distorts the current feedback used for torque-producing control. This article pro…
