Design of a stator-separated axial flux-switching hybrid excitation synchronous machine

A stator-separated axial flux-switching hybrid excitation synchronous machine (SSAFHESM) is introduced in this paper. The flux-leakage coefficient of SSAFHMSM is studied by finite element analysis (FEA) with the depth of non-magnetizer, and its field control ability is analyzed under different excitation currents. FEA results show that the flux-leakage coefficient is reduced evidently when the depth of non-magnetizer varies from 0 to 8mm, while it is almost not changed when the depth of non-magnetizer is greater than 8mm. Good field control ability is obtained in SSAFHESM.
