Electric Power Systems Research, 2012 This paper develops and analyzes a methodology for detecting stator winding inter-turn faults in surface-mounted permanent magnet synchronous motors. The proposed methodology is based on monitoring the zero-sequence voltage component having into account the effects of the inverter that usually feeds the machine.

IEEE Transactions on Energy Conversion, 2012 This paper develops and analyzes an online methodology to detect demagnetization faults in surface-mounted permanent magnet synchronous motors. The proposed methodology, which takes into account the effect of the inverter that feeds the machine, is based on monitoring the zero-sequence voltage component of the stator phase voltages.

A New PWM Control based on an Optimized Zero Sequence Component injection: Application in a Two-Level Inverter [PDF]
IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021 In this paper, a new optimization problem is proposed for improvement of PWM control of an inverter that supplies a generic RLE load. Two objectives functions are studied separately: Weighted Total Harmonic Distortion (WTHD) of load voltages and total losses.
