Abstract: This paper has reported the development and performance of a
flux-concentration type linear induction motor (FCLIM) utilizing the effect of
flux-concentration by eddy currents. In the developed FCLIM, the slot-leakage
flux is reduced and as a result more flux is concentrated into the air gap. The
key element of the FCLIM is the conducting plate inserted between the exciting
coils in each slot. Thrust characteristics of conventional tubular LIM and
FCLIM are compared using the equivalent circuit parameters. Though some losses
are occurred in the plate, the overall efficiency of FCLIM is better at higher
output force.
