Abstract: Permanent magnetic levitation technology uses the force between magnet and magnet or ferromagnet to achieve contactless support, which has the outstanding characteristics of no friction and low energy consumption. With the development of rare earth permanent magnet materials, the high remanence, high coercivity and high magnetic energy product improve the load-bearing performance of the permanent magnetic levitation system, which causes scholars have carried out many researches. China has the most reserves of rare earth resources in the world, and the development of permanent magnetic levitation technology has natural advantages and great significance. First of all, the mechanism and characteristics of permanent magnetic levitation technology are clarified. Secondly, the development history of passive levitation and active levitation is systematically reviewed. The magnetic circuit structure, levitation characteristics, and research status of three kinds of permanent magnet active levitation with air gap adjustment, magnetoresistive modulation and magnetic source regulation are described in detail. Thirdly, the technical difficulties such as magnetic circuit design and optimization, magnetic force accurate modeling, performance and control methods are analyzed, and the corresponding solutions are presented. Finally, the future application prospect and development trend of permanent magnetic levitation technology in gravity compensator, light load micro bearing, low frequency vibration isolation and other fields are prospected.
