PURPOSE: A rotor assembly and a motor including the same are provided to minimize dead zones at the boundary between the N pole and the S pole of a magnet, thereby increasing efficiency of the magnet. CONSTITUTION: A hub base(211) is fixed at the top end of a shaft. A rotor case(210) includes a magnet support part. The magnet support part is downwardly extended from the outer side end of the hub base in an axial direction. A magnet part(220) is disposed within the magnet support part. The magnet part includes magnets which are arranged to be spaced apart from each other at a predetermined interval. |
