In view of the high current carrying capacity,strong trapped magnetic field characteristics and Meissner effect of high-temperature superconducting materials,the application of high-temperature superconducting materials to magnetic transmission devices can significantly improve the torque density and transmission efficiency while realizing contactless torque transmission.The theoretical and applied research of high-temperature superconducting magnetic transmission has been carried out at home and abroad,and corresponding progress has been made.Taking high-temperature superconducting magnetic couplings and high-temperature superconducting magnetic gears as the research objects,this paper reviews the research status of high-temperature superconducting materials in the field of magnetic transmission from the aspects of structure and principle and modeling and analysis through the investigation of relevant literature at home and abroad.Based on this research status,we further discuss the problems and development prospects of high-temperature superconducting magnetic transmission in terms of innovative topology design,cooling and power supply,alternating current loss of superconducting magnets,multi-objective optimization of complex transmission characteristics.
