高温超导磁悬浮轴承研究综述

he superconducting　 levitation　system is one of the most prospective fields for application of superconductors. After high temperature superconductors appear, high temperature superconducting magnetic bearing (SMB) can realize self-stability because of pinning properties. As one of the applications of high temperature, superconducting magnetic levitation technology, high temperature superconducting magnetic bearing　can realize passive high-speed rotation through low power consumption without any friction or lubrication. To summarize the research and development status of SMB, the typical prototypes are described respectively from America, Germany and Japan as well as other domestic and foreign groups. The key technical parameters and present hotspot are proposed and discussed. Finally, applications of SMB in the future are disscussed.
