ABSTRACT:
A motor having a fluid dynamic bearing generating a fluid dynamic pressure by forming an oil gap between a rotor and a stator such that oil is accommodated in the oil gap, and a first and second air dynamic bearing generating an air dynamic pressure by forming an air gap between the rotor and the stator such that air is introduced into the air gap. The fluid dynamic bearing generates a fluid dynamic pressure by forming an oil gap between an axial hole of a sleeve and a shaft such that oil is accommodated in the oil gap, and the first and second air dynamic bearings generate an air dynamic pressure by forming an air gap between an inner circumferential surface of a hub and an outer circumferential surface of the sleeve and between the inner circumferential surface of the hub and an upper plane surface of the sleeve, respectively.
