Abstract:
An airfoil-magnetic hybrid bearing, which is a combination of a magnetic bearing and airfoil bearing includes a housing, an airfoil bearing, a magnetic bearing, coils, and a coupling segment. The housing is around a rotating shaft of a rotation device. The airfoil bearing is positioned between the housing and the rotating shaft to form dynamic pressure to levitate the rotating shaft during rotation of the rotating shaft. The magnetic bearing includes cores positioned radially between inner surface of the housing and outer surface of the airfoil bearing. The cores are projected to the center of the rotating shaft. The coils wound to the cores to levitate the rotating shaft using a magnetic attractive force generated by a current application thereto. The coupling segment is configured to couple the airfoil bearing to the magnetic bearing directly.
