Abstract
Since the single-sided linear induction motor has a finite length along the direction of its movement, the non-linear phenomena have significant impacts on the traction characteristics. The equivalent circuit of the linear induction motor is mainly established by two methods: the hypothetical distribution model and the quasi-1-D field analytical method. This paper mainly introduces a T-type equivalent circuit based on the quasi-1-D field analytical method, and comprehensively compares that based on the hypothetical distribution model. First, it proposes the transformation of the T-type equivalent circuit for the linear induction motor, and analyses the physical meaning of each parameter in the circuit. Second, an analysis method is briefly introduced, and the important correction coefficients to the end effects and other non-linear phenomena are derived. Third, the calculation procedures of thrust, vertical force and efficiency are proposed. Then, the characteristics in a prototype motor are calculated by using the T-type equivalent circuit derived from the analytical method, and the calculation results are compared with that based on the hypothetical distribution model. Finally, the experimental measurement results obtained by using a test rig verify the validity of the equivalent circuits.
由于单边直线感应电机沿运动方向的长度有限,非线性现象对牵引特性有很大影响。直线感应电机等效电路的建立主要有两种方法:假设分布模型和准一维磁场解析法。本文主要介绍基于准一维磁场解析法的 T 型等效电路,并对基于假设分布模型的等效电路进行了综合比较。首先,提出了直线感应电机 T 型等效电路的变换,并分析了电路中各参数的物理意义。其次,简要介绍了一种分析方法,并得出了对端效应和其他非线性现象的重要修正系数。第三,提出推力、垂直力和效率的计算程序。然后,利用分析方法得出的 T 型等效电路计算了原型电机中的特性,并将计算结果与基于假设分布模型的计算结果进行了比较。最后,使用试验台获得的实验测量结果验证了等效电路的有效性。
