600km/h급 초고속열차 용 공심형 LSM의 권선방식에 따른 특성 연구

Recently, an interest in a hybrid system combining only the merits of the conventional wheel-rail system and Maglev propulsion system is growing as an alternative to high-speed maglev train. This hybridtype system is based on wheel-rail method, but it enables to overcome the speed limitation by adhesion because it is operated by a non-contact method using a linear motor as a propulsion system and reduce the overall construction costs by its compatibility with the conventional railway systems. Therefore, design models of each coreless-typed Linear Synchronous Motor (LSM) with various distributed and concentrated windings for 600 km/h very high speed train maintaining the conventional wheel-rail method is derived, and a comparative analysis on electromagnetic characteristics of each model is finally conducted in this paper.
