ABSTRACT: This paper discusses the various possible uses of linear electric motors in railroads under particular operating conditions found in the United States. Performance characteristics of some linear motor designs are presented first to provide an illustration of the range of performance that can be expected from these motors. The paper then examines two specific uses of linear motors—a LIM booster- retarder for classification yards and an eddy-current brake for a high speed passenger train. The necessity for new components for these applications, the advantages offered by linear motors, and the possible problem areas, as well as some recommended solutions, are also discussed.
