휠-레일 방식 초고속열차용 초전도 선형동기전동기의 지상권선 방식별 특성 분석

초록

Recently, an interest in a hybrid system combining only the merits of the conventional wheel-rail systemand Maglev propulsion system is growing as an alternative to high-speed maglev train. This hybrid-type system isbased on wheel-rail method, but it enables to overcome the speed limitation by adhesion because it is operated by anon-contact method using a linear motor as a propulsion system and reduce the overall construction costs by itscompatibility with the conventional railway systems. Therefore, the design and characteristic analysis of a coreless-typesuperconducting Linear Synchronous Motor (LSM) for 600km/h very high speed railway system are conducted in thispaper. The designed coreless-type superconducting LSMs are the distributed winding model, the concentrated 1 layerwinding model and the concentrated 2 layer winding model, respectively. In addition, the characteristic comparison studieson each LSM are conducted.
