Multiobjective design optimization for high-temperature superconducting linear synchronous motors with different primary topologies

Abstract

A single-sided high-temperature superconducting (HTS) linear synchronous motor (HTSLSM) with an HTS bulk magnet array as its secondary has been developed in our previous work. This work presents multiobjective design optimization for this HTSLSM for its broad industry applications. Moreover, a new topology is presented for the primary of this HTSLSM. The finite element model used for the performance calculation has been verified by experimental results. Through the design optimization, it can be seen that the motor performances have been improved greatly for both initial and new topology primary structures.
