Finite element analysis of direct thrust-controlled linear induction motor

This paper describes the finite element analysis of a direct thrust-controlled linear induction motor (LIM). The time-stepping finite element method and the moving mesh technique are used to calculate the dynamic characteristics of the LIM during direct thrust control. Because the LIM has an end effect, a thrust correction coefficient is introduced to predict actual thrust in control. The simulation results, the thrust and the stator flux linkage are shown and the stator current is compared experiments.
