Abstract: A motor assembly includes a brushless direct current (BLDC) motor; a gear box in which the BLDC motor is installed; and a power transmission part having a plurality of gears installed in the gear box so as to transmit power generated by the BLDC motor to an ice bin. The BLDC motor comprises: a stator and a rotor rotating with respect to the stator, wherein the rotor may be connected to the power transmission part by a shaft and the stator may be coupled to the gear box in a separable manner.

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.
