Performance Analysis of a Rewound Multiphase Synchronous Reluctance Machine

open access: yesIEEE Journal of Emerging and Selected Topics in Power Electronics, 2022
This paper analyses the performance of synchronous reluctance motors (SynRMs) when an existing three-phase stator is rewound to a higher number of phases. The introduced rewinding technique offers an optimized distribution for air gap flux, higher winding factor and higher value for the fundamental component of the magneto-motive force with lower ...
