A method and apparatus for radial and axial hybrid bearings using gas sector(s) and magnetic sector(s) to increase bearing load capacity and stiffness, reduce bearing size and bearing span, and reduce cost comprises a stator and a rotor. An illustrative embodiment of a stator for use with a hybrid bearing may include one or more bearing pads positioned in a gas sector, and the stator may also include one or more magnetic sectors. The hybrid bearings may provide for the elimination of much of the magnetic bearing structure and associated power electronics using a pressurized gas/air bearing to react the bearing steady load while reserving the magnetic bearing and its controls to react dynamic loads and stabilize the bearing. In addition, the magnetic bearing controls for a hybrid bearing may be used to monitor bearing operating condition and provide communications of these conditions to the outside world. |
