Design and Performance Optimization of a Novel High Temperature Superconducting Linear Flux-Switching Motor

This paper proposes a new topology of a high-temperature superconducting linear flux switching motor (HTS-LFSM). The electromagnetic characteristics of this novel HTS-LFSM, including flux density, back-EMF, thrust force, and ripple, are analyzed. Key topology parameters of the HTS-LFSM are optimized, and its performance is compared with that of the traditional LFSPM. The comparison shows that the proposed HTS-LFSM can generate higher thrust force and smaller thrust ripple. The results indicate that the proposed machine offers more performance advantages for modern traffic. © 2023 IEEE.
