摘　　要：以一台容量5.5kW的直线感应电动机为例,在考虑纵向端部效应的情况下,将整个直线感应电动机模型作为求解域,采用有限元法对其磁场进行了数值计算。通过对磁场的分析,可以计算出直线感应电动机的运行特性。将理论计算结果与实验结果进行了比较,验证了计算方法的准确性。A 5. 5kW linear induction motor was taken as an example. In the condition of considering longitudinal ending effect, the magnetic field of the whole linear motor model as a solved domain was calculated in finite element method. By analyzing magnetic field, the operation characteristic of the linear induction motor was calculated. In the end, by comparing computed results with test results, the calculations prove accurate.
