A simple analytical method is developed to design novel axial field flux-switching permanent magnet (AFFSPM) machines in terms of back electromotive force (back-EMF) and cogging torque. The machine is proposed with E-shaped laminated segments in the stator. Some major parameters are originally designed with reference to those of a 12/10-pole U-core AFFSPM machine, including the rotor tooth width, the split radio of the inner diameter to outer diameter of the stator and the stator parameters. In this paper, they are investigated and optimized for attaining essentially sinusoidal back-EMF and low cogging torque by 3-D finite element method (FEM). Compared with 12/10-pole AFFSPM machine, it is shown that the volumes of magnets are almost reduced by 30%, while the similar output torque at the rated current can be obtained, and the ratio of the mutual-to self-inductance is largely reduced, which indicates the proposed motor has better fault-tolerant capability.
