高温超导直线感应电机的电磁优化设计

Electromagnetic optimization design of a HTS linear induction motor

主要给出了高温超导直线感应电机的设计和电磁分析方法.根据常规直线感应电机设计公式,结合遗传算法和约束条件得到了当前条件下最优化的电机参数.由于高温超导直线感应电机的特殊性,很难用公式法直接得到准确的电机优化参数,因此用有限元电磁分析软件Ansoft对得到的电机模型进行了性能分析,并根据分析结果修改电机参数,直到电机性能满足设计要求为止.

This paper presents the design and the electromagnetic analysis of a high-temperature superconductor（HTS） linear induction motor（LIM）.According to the formulas of the normal LIM,combined with genetic algorithm and the constraints,the optimal motor parameters could be obtained.Due to the particularity of the HTS LIM,it＇s difficult to obtain the accurate motor optimization parameters using the formula method directly.So the model of the motor is made and analyzed using the finite element electromagnetic analysis software Ansoft.According to the results the parameters of the motor will be modified until the characteristics meet the design requirements.
