Abstract

In this paper, a nonlinear magnetic circuit network model for the analysis of a three-phase 12-stator-slot/10-rotor-pole flux-switching permanent-magnet (FSPM) motor is proposed considering localized saturation effect, which enables the predictions of open-circuit air-gap field distributions, phase flux-linkage, phase back-electro-motive-force (back-EMF) and winding inductances waveforms. Further, a developed model with bypass-bridges is also proposed, which enables the winding inductances to be predicted with more accuracy. The predicted results are confirmed by both finite element analysis and experimental measurements.
