Study of the Maglev Performance of the Side- Mounted High-Temperature Superconductor Maglev Rotating System

Abstract

A new type of maglev system, a side-mounted high-temperature superconductor (HTS) maglev system, designed to run at high speed in an evacuated circular tube is presented in this paper. The levitation performance of the system was investigated. Results show that the stability of the maglev system is strongly dependent on the arrangements of HTS bulks along the center of permanent-magnet guideway. For the linear arrangement, the guidance force tends to drive HTS bulks away from the magnetic hill with the decrease of suspending gap. This may cause the levitation force decrease at the same time. In the comparison with the quadrilateral, square and liner arrangement of the HTS bulks, the triangular arrangement possesses the best maglev performance.
