摘　　要：针对轨道交通用大功率直线感应电动机,采用改进的T型等效电路模型进行了电机设计及特性计算,设计中考虑了电机的端部效应、端部半填充槽、次级反应板集肤效应等特殊结构问题。并据此设计制作了样机,样机实验结果与设计结果吻合。同时也给出了不同气隙下电机特性的计算结果。In this paper, an single-sided linear induction motor （SLIM） for urban transit was designed and its characteristics were calculated with improved T-type equivalent circuit model. The specific structure problems of an SLIM such as end effect, half-filled slots for the end windings skin effect were taken into account in the design. The prototype was tested, and the accuracy of the calculation was verified by experimental results. The calculation results in different length gaps were provided in this paper as well.
