Abstract :
The influence of stator and rotor pole numbers, viz. 6/5, 6/7, 12/10, 12/11, 12/13, and 12/14 stator/rotor poles, etc., on the electromagnetic performance of 3-phase flux-switching PM (FSPM) machines with all and alternate poles wound is investigated in this paper. It shows that the back-emf waveform, winding inductance, unbalanced magnetic force (UMF) and torque density in a FSPM machine are all significantly affected by the stator and rotor pole numbers and winding configurations, as confirmed by both finite element analyses and measurements.
