Propulsion and levitation forces in a single-sided linear induction motor for high-speed ground transportation

A realistic mathematical model of the single-sided linear induction motor (SLIM) is presented. Using this model, propulsion and levitation forces are computed for a SLIM with back iron. The validity of the analysis is verified by tests on a laboratory model. Some associated problems are outlined, and the feasibility of SLIM´s for high-speed ground transportation (HSGT) is discussed. With regard to HSGT, SLIM is compared with the double-sided linear induction motor.
