摘　　要：首先介绍了两种新型永磁电励混合励磁直线同步电机的结构与特点,然后运用ANSYS8.1软件包对两种型式的直线电机进行了气隙磁场的分析,给出磁场分布和电磁推力的分析结果,最后,与实物模型的试验结果进行了对照。This paper introduces the structure and charactenistic of two novel types of hybrid excitation linear synchronous motor with permanent magnet and electric excitation. The air-gap magnetic field of the two types of linear motors is analyzed with ANXYS8. 1 software pack. The results of the distribution of magnetic field and the electromagnetic propulsive force are shown. In the end,we compare the theoretical trsuhs with the expenrimental tesuhs of the actual model.
