Abstract
A fan motor apparatus having an improved heat-radiation performance includes a stator including an electronic device; a central shaft which is fixed onto the upper surface of the stator; a rotator mounted rotatably with the respect to the stator by being rotatably coupled to the central shaft; a heat-radiating fin portion provided on an inner surface of the rotator to generate wind toward the stator when the rotator rotates; and an cooling fin combined air flow guide formed on a surface of the stator to increase a heat exchange area for a heat exchange between the air generated by the heat-radiation fin portion and the air inside the stator; and at the same time guide the air from the exterior of the stator toward the central shaft so that the air is introduced into the rotator via a lower surface of the rotator.
