摘　　要：针对三维有限元法存在计算复杂、求解时间长,不适合工程设计应用等问题,在合理假设的基础上,根据磁路等效原理,对低速永磁直线同步电动机的三维电磁场进行了等效二维处理,建立了低速永磁直线同步电动机的拟二维电磁场模型.通过对所建立的拟二维电磁场模型进行有限元分析,并与三维有限元计算结果进行对比,发现二者有较好的拟合.且建立拟二维电磁场模型可节约大量的分析计算时间,并可完全满足工程设计的需要.3D Finite-Element Method （FEM） for computing complexity and consuming too much computing time and not suitable for applicntion of engineering design, based on reasonable assumptions, using the principle of mag netic circuit equivalence, the permanent magnet linear synchronous motor with low-speed （PMLSML） 3D electromagnetic fields was dealt with the equivalent 2D magnetic field. The quasi-planar electromagnetic model of PMLSML was constructed. Based on the model, the electromagnetic field was calculated by FEM, and the results are compared with 3D results, there are better fit. Using this model can save a great amount of computing time and fully meet the needs of engineering design.
