The present invention includes a fan which comprises a hub and a blade and generates wind by using torque; and an outer rotor fan motor which comprises a rotor rotating around the stator, is combined with the fan by a shaft, and provides the toque to the fan. The rotor includes a magnet which generates a magnetic flux for the rotation of the rotor; and a rotor frame which surrounds the magnet, is combined with the outer surface of the magnet, is separated from the hub by the shaft to prevent direct contact with the hub. So, the vibration transmitted from the motor to the fan can be blocked. |
