Abstract

As a direct electromagnetic driving device without adhesion, the urban transit with single-sided linear induction motor (SLIM) propulsion and wheel on rail support and guidance has many advantages, and has been a part of new type transit. In this paper, a SLIM for urban transit was designed and its characteristics were calculated with improving T-type equivalent circuit model. The specific structure problems of a SLIM such as end effects, half-filled slots for the end windings, skin effect have been taken into account in the design. The prototype has been tested, and the accuracy of the calculation is verified by experimental results.
