Thrust force calculation of LSM with asymmetric long stator

At curve section of track of long stator linear synchronous motors (LSM) for maglev train, the stators are asymmetric to compensate the distance difference between inner and outer tracks. In this paper, we calculate motor's flux density in suspension gap between stator and magnet, and then the thrust force of asymmetric LSM under different track-gap is described. The force loss because of the track gap between the girders with stator is numerically calculated. The array principle of stators and girders for LSM propulsion is introduced.
