Maglev bearing related products, which integrate the advantages of high speed and high precision, intelligent control, high efficiency and energy saving, low noise and environmental protection, and maintenance-free, are widely used in high-end manufacturing, fluid machinery, weapon equipment, municipal sewage, electronic crystal plate, biopharmaceutical, cement Building materials, iron and steel metallurgy, printing, dyeing and textile industries. Since the early 1980s, the domestic research on the theory and practice of magnetic suspension bearings has been carried out. After nearly 40 years of research and development, the main key technologies such as electromagnetism, machinery, control, mechanics, materials, and communication have been conquered, and the core of magnetic suspension bearings has been mastered. Technology, principle prototypes and related products developed by relevant scientific research institutions and enterprises are introduced as follows.
