Design of prototype superconducting hybrid electromagnet for high speed Maglev

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 LN2 is fabricated. From the expected operating current of the HTS coil, the levitation performance of the SH-EM is estimated.
