초고속 자기부상열차 적용을 위한 초전도 하이브리드 전자석 시작품의 설계

초록

This paper deals with the design and fabrication of prototype superconducting hybrid electromagnet(SH-EM) for EMS(Electromagnetic suspension)-based Maglev. The design requirements are based on the normal conducting EM used in the German high-speed Maglev. From the MMF- Levitation force curves simulated by FEM analysis, the required MMF by superconducting coil is suggested. As an experimental test setup to demonstrate the SH-EM, the experimental SH-EM with HTS coil cooled in LN₂is fabricated. From the expected operating current of the HTS coil, the levitation performance of the SH-EM is estimated
