Abstract
A fluid dynamic bearing motor is described. In one embodiment, the fluid dynamic bearing motor includes a stationary member and a rotating member. The motor further includes a fluid dynamic thrust bearing disposed along an axial surface of a sleeve. The thrust bearing is configured to axially support the relative rotation of the rotating member and the stationary member and to pump bearing fluid towards a corner of the sleeve. The motor also includes a fluid dynamic journal bearing disposed radially inboard of the thrust bearing along a radial surface of the sleeve, where the radial surface is adjacent to the axial surface. The journal bearing is configured to radially support the relative rotation of the rotating member and the stationary member and to pump bearing fluid to the corner of the sleeve.
