In this paper two different multi objective functions are developed. Each one will improve some of the motor characteristics, such as efficiency, power factor, end effect and motor weight. This procedure will be done by analytic method and using particle swarm optimization technique. In this paper a new equivalent circuit model has been used that include all specific effects of single-sided linear induction motors, and a new method will be suggested to evaluate intensity of end effect by help of equivalent circuit method. Results show the accuracy of the equivalent circuit model and the improvement of objective functions at the end of optimization procedure. Two dimensional finiteelement analysis will evaluates the analytical result.Index Terms--Efficiency, End-effect, Finite-element, Power factor.

Abstract:The linear rail transit system (LRTS) has the advantages such as high performance, low construction cost, easy maintenance, friendly with the environment, the researchers all over the world therefore has focused their interests on the LRTS. Despite its late start, China is marking a rapid progress on the study of the linear rail transit system. The LRTS in China can be divided into two types: maglev train system and the linear metro system. This article will revolve around the two aspects above to address the develop status and the newly research progress of the LRST in China. Meanwhile, the article also presents the research progress of the high-temperature superconducting (HTS) linear motors used for LRTS.
