摘要： There is provided a motor allowing for an increase in the rigidity of a hydrodynamic bearing by controlling a gap between a shaft and a sleeve as well as minimizing power consumption and a recording disk derive device including the motor. The motor includes a sleeve having a cylindrical shape and including a hole whose inner circumferential surface has at least one dynamic pressure groove therein; and a shaft rotatably inserted into the hole of the sleeve and having at least one rigidity reinforcing portion protruding in an outer diameter direction from an outer circumferential surface thereof corresponding to the dynamic pressure groove.

摘要： Disclosed are a motor and a recording disc drive apparatus that can prevent a fluid in a fluid dynamic bearing from being discharged to the outside. A motor according to an aspect of the invention may include: a shaft; a sleeve having a cylindrical shape and supporting the shaft such that the shaft is rotatable therein; a rotor case engaged with an upper end of the shaft and having a rotor main wall having a cylindrical shape and protruding from one surface thereof in order to receive part of the sleeve; and a cover engaged with an end portion of the rotor main wall and extending the rotor main wall, wherein at least two sealing portions preventing leaks of a fluid used to lubricate the sleeve are formed between an internal circumferential surface, defined by the rotor main wall and the cover, and an outer circumferential surface of the sleeve.
