A double-rotor permanent magnet reluctance motor was designed.The two-dimensional finite element model of the motor was established by using RMxprt module.Sensitivity analysis of key parameters affecting synchronous reluctance motor's torque was carried out,optimization variables were determined,variables were sampled hierarchically,and Kriging response surface models of average torque and torque pulsation were established.The optimal solution set was obtained by using particle swarm optimization algorithm.Finally,the feasibility of the optimization method was verified by simulation.The results show that the optimized motor performance was improved and the optimization goal was reached.
