PURPOSE: A hydrodynamic bearing assembly and a motor having the same are provided to prevent noise and vibration by preventing an adhesive from being spilled to the upper surface of a sleeve. CONSTITUTION: A hydrodynamic bearing assembly comprises a sleeve(120) and a hub(210). The sleeve supports a shaft. The hub is arranged on the upper part of the sleeve. A recessed groove is formed in the hub along the inner circumference, thereby being filled with an adhesive in the inner circumference corresponding to the upper outer circumference of the shaft. A filling groove is extended toward the upper part of the inner circumference of the hub. |
