Abstract: The traction performance of linear motor traction system highly depends on the electromagnetic force characteristics of linear motors, the electromagnetic force characteristics of linear motors for rail transit was investigated. Aiming at the linear induction motor, linear permanent magnet synchronous motor, and linear switched reluctance motor for rail transit, the electromagnetic force analytical models of the three types of motors were built. The structures of these motors were designed. Based on the designed motor structures, the finite-element electromagnetic models of these motors were established. Using the finite-element electromagnetic models, the electromagnetic force characteristics of these motors were obtained. The comparison analysis of the electromagnetic force characteristics of these motors were performed. The analysis results can provide the theoretical and design referencesfor linear motors in rail transit.

Key words: rail transit, linear induction motor(LIM), linear permanent magnet synchronous motor(LPMSM), linear switched reluctance motor(LSRM), electromagnetic force characteristics, finite element analysis
