Resumen:
A new strategy is proposed here for the diagnosis of asymmetric demagnetisation in permanent magnet synchronousmachines. The strategy is based on the measuring of the voltage at the midpoint of the windings within a phase. Unlike thephase voltage, for a fault situation, the midpoint voltage shows sidebands around the fundamental component, which allowsdetecting and quantifying the demagnetisation phenomenon. A low-cost implementation for the automatic detection of faults isalso proposed in the present study and experimental results are presented to validate the strategy.
