Design and electromagnetic analysis of a prototype HTS Linear Induction Motor

This paper presents the application of Genetic Algorithm (GA) and the Finite Element Method (FEM) for optimal design of a High Temperature Superconducting Linear Induction Motor (HTS LIM). 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. In order to improve the motor critical current, it should be as little as possible. Finally, the electromagnetic characters of the motor are analyzed. From the results, it is known that the design method is accurate for the HTS LIMs.
