直线感应电动机次级受力及速度分析

结合等长初、次级直线感应电动机的特点，在一般感应电动机等效电路的基础上导出了其等效电路。用分层转移矩阵法求出了次级钢板的参数。给出了该种电机静、动态特性分析法。样机特性的计算值和测试值基本相符，说明分层转移矩阵法特别适用于解决具有整块次级的电机问题。

Research of Linear Induction Motors Secondary Force and Velocity

According to the featUres ofLIM with same length elementary, secondary, its equivalentcircuit is obtained based on the that ordinary induction motors. The parameters of the secondary steelplate are obtained with layer-built transfermatrix. The characteristics of this kind of electrical machineare analyzed. The calculated value of a sample motor agrees with its test value. It is shown that the methodof layer-built transfer matrix is especially suitable to solving the problem of induction motor with integrate secondary.
