Abstract

This paper presents an optimization analysis of an axial flux-switching hybrid excitation synchronous machine (AFHESM) to improve its no-load electromagnetic performances. The shapes of permanent magnet (PM), rotor-teeth and stator slot of AFHESM are investigated for a better design scheme by finite element analysis (FEA). Some optimal results under no-load are achieved, which mainly including the induced electromotive force (EMF), cogging torque and field control ability. Both FEA and experimental results show that the induced EMF can be improved when PM shape coefficient is 0.95 and the rotor-teeth bevel angle is 6°.
