Abstract: PURPOSE: A fluid dynamic bearing assembly and a motor including the same are provided to effectively prevent a leakage of fluid by using a sintering stopper. CONSTITUTION: A fluid dynamic bearing assembly(100) includes a shaft(110), a sleeve(120), a stopper(190), and a hub(210). The sleeve inserts a shaft in order to be rotatable. The hub is equipped in the upper end of the shaft and includes a wall part which is protruded to the lower part of axial direction. The stopper restricts the flotation of the hub by being equipped in the inner side of the wall part and forms an oil interface between the inner surface of the inside diameter direction and the outer surface of the sleeve. The stopper makes air porosity of an oil filling part smaller than air porosity of other parts.
