Design of Automotive HTS Magnets for High-speed Electric Maglev
The superconducting magnet based on the second-generation high-temperature superconducting (HTS) tape can work at 15 K to 77 K. Compared with the low-temperature superconducting (LTS) magnet working below 4.2 K (the liquid helium temperature zone), the refrigeration cost of HTS magnets is lower, whi...

| Summary: | The superconducting magnet based on the second-generation high-temperature superconducting (HTS) tape can work at 15 K to 77 K. Compared with the low-temperature superconducting (LTS) magnet working below 4.2 K (the liquid helium temperature zone), the refrigeration cost of HTS magnets is lower, which can get rid of the scarce resources of liquid helium in China.In this paper, the primary design of the overall structure of high temperature superconducting magnet was carried out based on the open data of the vehicle mounted low temperature magnet of the standard Yamanashi maglev test line. Based on the finite element simulation, the electromagnetic and mechanical transfer structure and heat leakage of the magnet were analyzed, and a comprehensive design scheme of the vehicle mounted high temperature superconducting magnet suitable for full-scale and high-speed electric maglev was obtained. |
