This paper presents a summary of an experimental research project to evaluate a single sided linear induction motor (SLIM) as an integrated suspension/ propulsion system (ISPS) for guided ground transportation vehicles. Experimental results for rotating wheel tests of a full size section of a SLIM are presented. Emphasis is given to an application in the speed range of 200 to 500 km/hr; however, an extension of the results to lower speeds can be realized with further study of the data acquired. The results indicate that feasibility in such an application is limited to the extent that the adjudged benefits of ISPS outweigh the cost of the required onboard power conditioning unit (PCU). The size of the PCU increases with speed, nominal airgap, and the guidance/lift ratio desired. Results are presented to define the maximum practical speed for application as a function of the state of the art of PCU technology.
