Abstract—After the man-loading high temperature superconducting (HTS) Maglev demonstrations have been tested successfully, its future application attracts more and more researchers and engineers. The paper reviews the recent development of HTS Maglev system in China, one of the representative research groups. In the past seven years, quasi-static forces, dynamic characteristics and running performance have been studied based on magnetic levitation (maglev) performance by three HTS maglev measurement systems and 11-ch vibration measurement apparatus. For the further engineering application of HTS Maglev train, some practical problems are considered in detail, like inhomogeneous magnetic field along the forward direction, construction cost, high efficient propulsion design, and so on. On the other hand, a systemic method is presented to analyze or optimize the origin high temperature superconductor and permanent magnetic guideway system. Primary running parameters or notes are obtained for the future practically safe HTS Maglev system design. Besides, a low-mid speed HTS Maglev test line prototype is being on the plan with max 100 km/h speed, which will be helpful to the first step of the HTS Maglev engineering.
