Linear induction motors (LIMs) have been widely applied in railway transportation systems in the past thirty years. This is basically due to its merits of simple structure, less energy consumption, less manufacturing cost, etc. However, for the LIMs special characters such as cut-open magnetic circuit and large air gap length, survey on LIM is much more dififcult than traditional rotary motor. This paper brielfy describes merits, four main structures and characters of linear induction motor applied in railway transportation. The paper summarizes research and development of linear induction motor at home and abroad, and discusses several key technology problems.
