Design of coreless-typed linear synchronous motor for 600km/h very high speed train

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 hybrid-type 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, designs of each coreless-typed LSM with a distributed winding and a concentrated winding for 600 km/h very high speed train maintaining the conventional wheel-rail method is conducted, and a comparative analysis on electromagnetic characteristics of each model is finally conducted in this paper.
