COMPARISON OF LINEAR INDUCTION MOTOR THEORIES FOR THE LIMRV AND TLRV MOTORS

The Oberretl, Yamamura, and Mosebach theories of the linear induction motor are described and also applied to predict performance characteristics of the TLRV & LIMRV linear induction motors. The effect of finite motor width and length on performance predictions is examined for each theory. The edge and end effects are shown to play a dominant role in determining motor performance. The LIM thrusts predicted by the Oberretl, Yamamura, and Mosebach computer models are in reasonable agreement over most of the LIM speed range. The Oberretl theory tends to predict somewhat lower thrust values than the Yamamura and Mosebach theories; possible causes for the divergent thrust predictions are discussed. Computer listings for the Oberretl and Yamamura linear induction motor theories are presented in the appendix.
