Analytical Modeling and Optimization of a Single-sided High Temperature Superconducting Linear Induction Motor

In this paper, an improved analytical model is presented for calculating the performance of single-sided linear induction motor that primary windings are made of high temperature superconductor (HTS). The analytic model based on accurate subdomain, which the electromagnetic state of the superconductor can be taken into account, for predicting the magnetic field and analyzing the structural parameters on performance in HTS SLIM. As compared with the conventional analytic model, the accuracy of the proposed model, respecting the constraints linked to the physical and mechanical properties of the considered HTS tape, is observably improved. Finally, the finite element analysis (FEA) is used to verify the analytic model and compare it with the experimental results obtained from the prototype of HTS SLIM.
