Abstract :
In this paper, a coupled-circuit model developed by the authors is used to analyze the dynamic performance of a linear induction motor (LIM) with slip frequency control. The characteristics of slip frequency control under constant current conditions in both motoring and braking operation and at constant voltage are presented. Finally, the performance of an urban transit LIM under slip frequency control in both constant current and voltage drive regions is investigated. Where feasible, computer simulation results are compared to test measurements from operational linear induction drives
