Performance analysis of a linear synchronous motor with HTS bulk magnets

The study on high temperature superconducting (HTS) bulk magnets and their application has attracted much attention. This paper presents the performance analysis of a linear synchronous motor (LSM) with HTS bulk magnets for driving an HTS maglev vehicle model. Finite element magnetic field analysis is carried out for computing the magnetic field distribution and key parameters of the LSM, and an equivalent electrical circuit is then applied to predict the motor performance, showing that the presented motor is appropriate for driving the model vehicle. The LSM has been prototyped, installed in the maglev vehicle model, and tested for validating the theoretical analysis.
