흡인제어식 초고속 자기부상열차용 Prototype 초전도 하이브리드 자기부상시스템 개발

초록

This paper deals with the development of a prototype superconducting-hybrid magnetic levitation system for high-speed EMS Maglev. The electromagnet was designed to interface with the existing propulsion system used in the German high-speed Maglev. The rating levitation force of the magnet was designed to correspond to the weight of the magnet at a 20 mm levitation gap. Electromagnetic forces were simulated and compared with the test results in order to verify the design feasibility of the levitation system. The system was successfully demonstrated up to the vehicle running speed of 500 km/h. Operating tests revealed that the HTS-EM was fully operational in zero-power control mode. And the operability of the system was finally verified in this study.
