Design and Electromagnetic Analysis of HTS Linear Induction Motor

本文介绍了高温超导直线感应电机的设计和电磁分析方法。首先,使用遗传算法得到一组优化的电机参数;然后,为了确定电机参数的准确性需要用有限元方法对得到的电机参数建模仿真;垂直穿过高温超导绕组的磁场(垂直磁场)对电机的临界电流影响很大,为了增加电机的临界电流,穿过电机初级超导绕组的垂直磁场应该尽可能地小。最后,要对建立的电机模型进行详细的电磁分析,以保证各项性能指标满足要求。

This paper presents the design and the electromagnetic analysis of the high-temperature superconductor（HTS） linear induction motor（LIM） using Genetic Algorithm （GA） and Finite Element Method（FEM）.Firstly,the GA method is used to produce a series of optimal design data.Secondly,the model of the motor using the optimal data should be analyzed with the finite element method in order to confirm the accuracy of the model.The perpendicular magnetic field of the HTS coils has a great impact on the critical current of the motor.In order to improve the critical current,it should be as little as possible.Finally,the electromagnetic characters of the motor are analyzed.
