摘　　要：以直线感应电动机为例,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。分析了次级为不同电导率材料时的气隙磁场,并采用傅里叶谐波方法将气隙磁场分解为空间基波和一系列谐波,相应给出了采用能量法对初级漏抗、起动电流的计算。最后将理论计算与实验结果进行比较,验证了计算方法的准确性。In this paper, A linear induction motor is taken as an example, the whole motor model is solved, and its magnetic field is calculated by finite element method. In virtue of Fourier harmonic analysis, the air gap magnetic field corresponding to different conductivity in secondary conductive plane is divided into spatial fundamental waves and a series of harmonic waves, and the calculations of primary leakage reactance and starting current are given. In the end,by comparing the theoretical calculation results with experimental results, it proves the calculation method to be accurate.
