Magnetic bearing, also known as automatic magnetic suspension bearing; is a new type of high-performance bearing without mechanical contact between the rotor and the stator. It consists of mechanical components, electronic control system, sensors and auxiliary bearings. The electromagnetic force is used to suspend the rotor in space. It has the advantages of no mechanical wear, low energy consumption, high speed, low noise, long life, no smooth medium, etc. The magnetic bearing is selected as the support of the molecular pump rotor; it can fundamentally deal with the smooth grease brought by the smoothness of the traditional bearing. The problem of oil vapor backflow on the vacuum chamber and other problems; the magnetic bearing vacuum molecular pump becomes the preferred ultra-high vacuum acquisition equipment for integrated circuit manufacturing equipment. The magnetic bearing is a revolutionary change in the bearing profession after the oil is smooth and the gas is smooth; Traditional industries have added high-tech products. This fine mechatronics product; in addition to use in vacuum molecular pumps; also has a broad vision in the military, aerospace, petroleum and petrochemical, power and other categories.
