英文摘要：
The electromagnetic performance and optimization design method of a single winding bearingless switched reluctance motor（ BSRM） were studied. The general relationship between the radial force and structure parameters were given based on finite element method（ FEM）. Accordingly,the stator pole arc and rotor pole arc were selected as the optimization parameter and the extreme learning machine（ ELM） was used to build the optimization model. Besides,the particle swarm optimization（ PSO） algorithm was used to search for the optimal solutions. Finally,the comparative simulation results had proved that the proposed method had high precision and fast regression speed,and the accurate optimal solutions had been achieved.
