Abstract
A fan-motor assembly includes a fan which includes a hub and blades and generates a wind by using a rotational force, and an outer rotor fan motor which includes a stator and a rotor rotating at the periphery of the stator and is coupled to the fan by a shaft to provide the rotational force to the fan. In the fan-motor assembly, the rotor includes a magnet generating magnetic flux for rotating the rotor, and a rotor frame which surrounds the magnet to be coupled to the outer circumferential surface of the magnet and is spaced apart from the hub by the shaft so as not to be directly contacted with the hub.
