This paper presents a general analytical subdomain model for the computation of magnetic field distribution in any number of stator slots and rotor poles with and without electrically-excited, permanent magnet-excited and hybrid-excited multiphase flux switching machines (FSM) topologies. The goal of this work is to elaborate an analytical general method based on subdomain model for predicting magnetic field in any FSM topology with defining in advance the number of subdomains and affect the general form of vector potential in each subdomain. The presented general subdomain method is comparable to finite element method (FEM) where the mesh elements can be compared to the number of harmonic terms used in each subdomain.
