Abstract
A rotating machine including a thrust bearing configured to receive an axial thrust exerted by a rotor. The thrust bearing may be configured to transfer the axial thrust from the rotor to a housing or other structural component of the rotating machine using a plurality of ball bearings. The rotating machine includes a magnetic apparatus configured to cause the rotating machine to exert an axial force on the thrust bearing in the direction of the axial thrust of the rotor, such that the magnetic apparatus loads the ball bearings in the direction of the axial thrust. The magnetic apparatus may be configured to generate a magnetic field causing a first magnetic component of the magnetic apparatus to repel or attract a second magnetic component of the apparatus. The first magnetic component may be configured to rotate relative to the second magnetic component.
