单边复合次级直线感应电机的多层傅利叶分析

MULTILAYER FOURIER ANALYSIS OF SINGLE SIDED LINEAR INDUCTION MOTORS WITH COMPOSITE SECONDARY

使用傅利叶方法求解单边复合次级直线感应电机的二维模型场，将次级场域分成多层，较为准确地求解了电机的磁场分布和运行特性，实验结果证明了方法的有效性．

The two dimensional electromagnetic field in a single sided linear induction motor with composite secondary is solved with Method of Fourier Transformation.By dividing the secondary into layers,a fairly accurate field distribution in the air gap and in the secondary,as well as the performance of the motor,is computed.Agreement of calculated values with test results shows the validity of the method.
