Abstract  A magnetic bearing is a new support bearing, which can suspend a rotor in the space by magnetic forces without machinery contact between the rotor and the stator. So a magnetic bearing has a vast application prospect in the fields of aeronautics and astronautics, mechanical industry, life sciences and so on. In this paper, firstly, the application and development at home and abroad are reviewed. Then the definitions for magnetic bearings are summarized. Finally, the structure types (magnetic bearings with sensors and sensorless magnetic bearings) and modeling approaches on suspension forces (modeling methods based on magnetic bearings with sensors and sensorless magnetic bearings) are systemically expounded.
Key wordsMagnetic bearing      application and development      key technologies      structure      modeling on suspension force
