Long-primary single-sided linear induction motors (SLIMs) have unique advantages in some applications such as an electromagnetic launcher with higher force density and acceleration due to its lightweight secondary conductive sheet compared with other types of SLIM having different structures. Furthermore, long-primary SLIM will have superiorities without any friction loss and guidance control system when it is combined with high temperature superconducting (HTS) magnetic levitation system. In this work, a long-primary SLIM integrated with HTS levitation system is designed. This paper presents the design and performance analysis of the SLIM levitated by a HTS levitation system, and the magnetic field finite element method is applied to analysis its magnetic flux distribution, thrust force and normal force characteristics with results obtained. Finally, the preliminary motor running testing results are also presented. © 2009 IEEE.
