An Axial-Flux Hybrid Excitation Flux-Switching Machine

Abstract:

A flux switching permanent magnet (FSPM) machine has the advantage of high power density, high torque density, inherently sinusoidal back EMF, stable structure, and the disadvantage of magnetic field uncontrollable. This paper proposes a novel axial-flux hybrid excitation flux-switching (AFHEFS) motor, which offers three phase symmetrical sinusoidal flux linkage and linearly regulated electromagnetic torque as well as excellent flux regulation capability and even field elimination ability with a size ratio of 1:2 between PM stator and electrical stator. The results are validated by 3D finite element (FE) analysis.
