ABSTRACT:
A fluid dynamic bearing motor is described. In one embodiment, the fluid dynamic bearing motor includes a stationary shaft having a first end coupled to a first plate and a second end coupled to a second plate. The motor also includes a hub that is configured to rotate relative to the shaft. A fluid dynamic journal bearing, disposed between the shaft and the hub, radially supports the relative rotation of the shaft. The motor further includes a first seal, which is defined in part by the first plate and is disposed radially outboard of the journal bearing, and a second seal, which is defined in part by the second plate and is disposed radially outboard of the journal bearing.
