Finite element analysis of direct thrust-controlled linear induction motor

This paper describes the finite element and the moving mesh technique are u sed to calculate the dynamic characteristics of LIM during the direct thrus t control. Because LIM has the end effect. thrust correction coefficient is introduced to predict an actual thrust in control. The simulation results, the thrust and the stator flux linkage are shown below and the stator anal ysis of a direct thrust-controlled linear induction motor(LIM), The time-st epping finite element method and the moving mesh technique are used to calc ulate the stator flux linkage are shown below and the stator current is com pared with an experimental one.
