Abstract
A torque converter and an electronic driver circuit are described that will generate a compensating applied torque that is equal and opposite to the frictional torque of a bearing over a range of angular velocities. The compensated bearing is effectively frictionless. The frictional torque is assumed to have a constant component and one that is proportional to the angular velocity.
