Abstract：Based on the structural characteristic of flux-switching machines with segmental rotor, the drawing method of distribution diagram and the coil-EMF vector graph, which illustrate the space and electrical angle difference of the coils respectively, was developed and verified by finite element analysis method at the beginning of the paper. Further, a phase winding division method, which is suitable for any phase segmented-rotor flux-switching machines, was proposed and also confirmed by finite element analysis method. In further, based on the analysis of the single coil harmonic characteristics and the coil-EMF vector graph developed in this paper, the principle of combination of stator teeth and rotor pole numbers to achieve back-EMF without even harmonic was given and also verified by finite element analysis method. At last, guided by the phase winding division method and the principle of combination of stator teeth and rotor pole numbers proposed in this paper, a 3-phase segmented-rotor flux-switching machine prototype was designed and the experiment results verified the above research conclusion well.
