Abstract
A thrust compensation apparatus for high-speed rotating machinery includes an electromagnetic thrust bearing having a thrust rotor and a thrust stator, a first chamber filled with a pressurized medium on one side of the bearing, and a second chamber on the other side of the bearing. The pressure differential across the bearing augments the electromagnetic force between the rotor and stator in order to counteract the axial thrust load of the high-speed rotating machinery.
