Abstract:

Superconductivity (1911) and magnetic levitation (1912) each has gone through 100 years of history. Superconducting magnetic levitation (Maglev) train originated the invention in 1966, this low temperature superconducting maglev (LTS Maglev) train from invention to complete the manned operation has gone through nearly 50 years of history. On the last day of a last century high temperature superconducting(HTS)Maglev vehicle “Century” is succeeded in China, so far has gone through 15 years of development history. This paper introduces the research and development of HTS Maglev vehicle, including the 1G (Bi) and 2G (Y) HTS wire Maglev vehicle, and HTS bulk Maglev vehicle. The comparison for the magnetic levitation principle between the tape Ⅰand the type Ⅱ superconductor in the applied magnetic field is mainly discussed. The research progress of magnetic levitation system using HTS ReBCO bulk is given in the world. The medium/ low speed HTS Maglev development process in the ASCLab is presented from “Century” in 2000 to ETT HTS Maglev vehicle in 2014, finally discussed the possibility of application of high / ultra-high speed.

Key words: Low temperature superconductors, high temperature superconductors, maglev, vehicle, train
