Abstract
In the case of conventional type tubular linear induction motor (LIM), due to the higher value of leakage reactance, the air gap flux is decreased. In the flux-concentration type linear induction motor (FCLIM), the leakage flux is reduced considerably and more flux is concentrated into the air gap, resulting in an increase of the developed thrust. The performance characteristics obtained using per phase equivalent circuit parameters are not accurate mainly due to the configuration of the primary core with ends and the unbalanced input voltages. In this paper the performance characteristics of FCLIM and normal tubular LIM are compared using threephase equivalent circuit parameters, which are determined considering the unbalanced input currents and mutual reactances.
