Abstract
Provided herein, is an apparatus that includes a fluid dynamic bearing, a hub, and an induction housing. The fluid dynamic bearing is defined by a stationary component and a rotatable component. The hub is configured to rotate relative to the stationary component. A current is induced within the induction housing resulting from the relative rotation. The induced current creates a repulsive force between the stationary component and the hub.
