Fan apparatus including a fan, a shaft coupled to the fan for transmission of driving force from a motor to the fan, a rotor bushing of an insulating material joined to a rear end portion of the shaft, a rotor joined to the rotor bushing for transmission of the driving force to the shaft through the rotor bushing, and a stator mounted so as to be positioned on an inside of the rotor to form a BLDC motor together with the rotor, thereby reducing noise and enhancing fan efficiency by employing the BLDG motor which can make stable operation of the fan and increase an air flow rate.
