| In this paper, the electromagnetic performances of a novel axial field flux-switching fault-tolerant (AFFSFT) machine are investigated based on equivalent magnetic circuit (EMC) method. A nonlinear EMC model of the AFFSFT machine is proposed and built, and the static characteristics of the machine, including the air-gap flux density, permanent magnetic flux linkage, back electromotive force (EMF) and inductance characteristics are analyzed. The calculated results are compared with those predicted by finite element method (FEM). Experiments are done with a prototype. The analysis results are consistent with the experimental results well, verifying the feasibility of the EMC method. |
