Compared with the traditional flux switching permanent magnet machine, flux switching permanent magnet memory (FSPMM) machine has two kinds of permanent magnets, flux regulating windings and complex flux path. In this article, a three phase FSPMM machine with 12 stator slots and 14 rotor poles is optimized by numerical simulation software. After the pole-arc optimization, there is only one suitable skewed slot degree of rotor that can further increases the sinusoidal degree of back electromotive-force (EMF) of FSPMM machine, and decreases the amplitude of EMF slightly. Besides, the flux regulating of FSPMM machine includes enhance flux is analyzed by numerical simulation software. Lastly, a prototype of FSPMM machine is constructed, and the obtained numerical simulation results are verified by experimental tests. The simulation and experimental results may be benefit for the research of operational control, flux regulation and industry application of FSPMM machine in future.
