Abstract
A fluid dynamic bearing motor is described. In one embodiment, the fluid dynamic bearing motor includes a base that has a bore hole and a liner secured within the bore hole. The fluid dynamic bearing motor also includes a rotor assembly that has a shaft, which is partially disposed within the liner and configured to rotate relative to the liner. A fluid dynamic bearing is disposed between the liner and the shaft to support this relative rotation.
