Combined with the characteristics of permanent magnet linear synchronous motors,a structure of magnet-moving PMLSM suitable for the ultra-power occasions was proposed.The impact of motor thrust and cogging force imposed by the related structural parameters was studied by using FEA method,obtaining the method to calculate the fluctuation cycle of cogging force,the affecting curves of the thrust and thrust fluctuation between the relevant structural parameters.The cogging force wave curves under different structural parameters were also gained.The thrust force of PMLSM was tested and the experimental results were in good agreement with FEA results,thus proving the correctness of the analysis results.
