Double stator and single rotor type single-phase flux switching axial flux permanent magnet motor

In this paper, a new single-phase flux switching axial flux permanent magnet motor (FS AFPM) is presented. It has a double stator and single rotor (DSSR) disc-type structure. The rotor disc is a simple salient pole rotor, and it is sandwiched between the two stator discs. The permanent magnets (PMs) are embedded in the stator discs, which also contain the single-phase windings. To enhance the self-starting torque capability and unidirectional rotation, the rotor pole is chamfered. The characteristic analysis of the proposed DSSR type single-phase FS AFPM is carried out using the 3D finite element analysis (FEA).
