This paper studies the optimal design of a double-sided linear flux switching permanent magnet motor (DLFSPM) to improve the average thrust generated by motor operation and reduce the fluctuation range of thrust applying the Response surface methodology (RSM) and Particle Swarm Optimization (PSO). An analytical mathematical model of the electromagnetic thrust force of the DLFSPMs is developed. The functional model of the optimization parameters and objectives based on the RSM is constructed. The finite element analysis (FEA) is used to carry out numerical experiments on the geometric structure design variables. PSO is applied to an optimization tool for optimizing the DLFSPMs' mover structure parameters. Finally, the FEA comparison and analysis of the optimization results with the initial results reveal a significant improvement in the electromagnetic characteristics of the DLFSPMs. The feasibility and effectiveness of the optimization method are verified by the FEA results.
