On linear synchronous motor (LSM) for high speed propulsion

This paper presents the steady state performance characteristics of the LSM fed from a voltage-source frequency converter. A model, similar to the one used for conventional synchronous motor analysis, has been used to study the steady state behaviour of the LSM system. The results of the following investigations are discussed in this paper: Effects of various section lengths of the guideway winding on the performance characteristics of the LSM system, behaviour of the LSM system at different speeds, and a comparative study of the Linear Induction Motor (LIM) and LSM systems.
