PURPOSE: A hydrodynamic bearing assembly and a motor with the same are provided to easily grasp the existence of the inflow of bubbles inside a lubricant fluid, thereby easily determining whether a product is faulty or not. CONSTITUTION: A hydrodynamic bearing assembly (100) includes a sleeve (120) and a base cover (150). The sleeve supports a shaft (110) to be rotatable. The base cover is joined to the sleeve while maintaining a gap on the lower part of the axial direction of the sleeve. The base cover is transparent. |
