A semi-high-speed Maglev train with maximum speed of 200 km/h is being developed in Korea. It uses LIM as thrust and electromagnetic suspension as the levitation method. Owing to the compatibility of the rail with the previously developed urban Maglev train, the guidance magnet is placed near the levitation electromagnet. In that case, if power is applied to the levitation and guidance magnets, mutual...
This paper investigates the electromagnetic coupling effect between the levitation and guidance systems of a semi-high-speed Maglev train. Semi-high-speed Maglev trains are equipped with active lateral guidance systems to deal with crosswinds and high-speed operation in curves. Guidance magnets are located near the levitation system and share the same core, thus causing electromagnetic coupling. Both...
This paper describes the levitation and guidance characteristics of a semi-high-speed magnetic levitation (MAGLEV) vehicle. For a MAGLEV, which operates at 200 km/h, the guidance magnet is essential for high-speed operation at curves and against a side wind. The levitation and guidance magnets are electromagnetically and dynamically coupled, because both are used in a single rail. Because of the interactions...
