The Study on Propulsion Force Character of an Integrated Operation System for HTS Maglev Train

The high temperature superconductor (HTS) maglev train has several merits in compare with other ones. In our previous work, the feasibility of using electromagnetic guideway (EMG) in HTS maglev trains has been verified and the HTS bulk is proved to gain repulsive force in a reversed magnetic field, which can be used for propulsion function based on EMG in HTS maglev train. In this paper, the repulsive force under different factors are experimented in both EMG unit and segment. With the single EMG unit, the propulsion force under different levitation height, different operation velocities and the hysteresis of propulsion force are discussed. With a 60 cm EMG segment, the periodicity of propulsion forces is discussed and a free propulsion experiment were conducted. The results verify the feasibility of a levitation, guidance and propulsion integrated operation system in HTS maglev train and can support the further development of it.
