Abstract:
 Because of the complexity of magnetic field,it is difficult to calculate the magnetic field of flux switching permanent magnet( FSPM) motor by analytical method. The analytical model of E-core FSPM motor was advised with the subdomain method. The whole domain was divided into several subdomains based on the electronic and magnetic properties,and the partial differential equations were built in all subdomains. With the general solution and boundary condition,the magnetic vector potential was ob-tained. Then the flux density,coil flux and coil EMF were calculated. At last,the calculated results are verified with finite element method( FEM) . Although the saturation can not be considered in the analyti-cal model,it is very useful in the initial design and optimization design of FSPM motor because of the short computation time.
