摘　　要：介绍了两种新型的永磁电励混合励磁直线同步电机的结构与特点。然后运用AN SYS8.1软件包对两种型式的直线电机进行了气隙磁场的分析 ,给出了磁场分布和电磁推力的分析结果。最后 。This paper introduces the structure and characteristic 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 ANSYS8.1 software pack. The results of the distribution of magnetic field and the electromagnetic propulsive force are shown. In the end, we compare the theoretical results with the experimental results of the actual model.
