This paper analyzes partial demagnetization faults in a five-phase permanent magnet assisted synchronous reluctance motor (fPMa-SynRM) incorporating ferrite magnets (PMs). These are relevant because of the application field weakening, or due to high operating temperatures short circuit currents, PMs can become irreversibly demagnetized, thus affecting performance and safe operation machine. proposes fault indicators detect such modes with low levels between 5.0% 16.7% relative...

Inter-turn winding faults in five-phase ferrite-permanent magnet-assisted synchronous reluctance motors (fPMa-SynRMs) can lead to catastrophic consequences if not detected a timely manner, since they quickly progress into more severe short-circuit faults, such as coil-to-coil, phase-to-ground or phase-to-phase faults. This paper analyzes the feasibility of detecting harmful their early stage, with only one short-circuited turn, there is lack works related this topic multi-phase fPMa-SynRMs....
