Abstract
A coupled-circuit model is used to analyze the transient and dynamic performance of a linear induction motor (LI). The behavior of a LIM during acceleration and deceleration, under fault conditions, in response to a step frequency change when it is connected to an inverter supply and under slip-frequency control is studied. The LIM parameter changes and the consequent transient behavior brought on by changes in rail top-cap conductivity and dynamic changes of the air gap are also presented. The thrust, speed, and secondary sheet currents are evaluated under various transient conditions. Computer simulation results are compared to test measurements from operational LIMs.<>
