Patent ID: 7959357

Claim:
A fluid dynamic bearing motor comprising: a base having a closed end and an upstanding section extending from the closed end, the upstanding section and closed end defining a bore in the base; a stationary liner in the bore having a longitudinal wall and further having a bottom that is contiguous with the longitudinal wall extending radially inward from the longitudinal wall, the bottom defining a passage through the stationary liner, the liner positioned in contact with the closed end of the base and the upstanding section of the base; a rotor assembly having a shaft that is rotatably supported within the liner; a fluid dynamic bearing disposed between the shaft and the longitudinal wall; a capillary seal between the shaft and the liner having a close mating relationship end in fluid communication with the fluid dynamic bearing and an opposing diverging mating relationship end defining an inlet reservoir; and a channel outside the liner being recessed into the closed end and upstanding section of the base and in fluid contact with an outer surface of the liner, the channel operably fluidly communicating recirculating fluid from the fluid dynamic bearing via the passage to the inlet reservoir.
