Fan motor

Abstract

The present embodiment comprise: an inner housing having an inner space formed therein; a rotation shaft assembly supported in the inner housing and having a rotor and a bearing mounted on a rotation shaft thereof; a stator disposed to surround the rotor in the inner housing; an impeller connected to the rotation shaft; an outer housing surrounding the outer periphery of the inner housing and having an inlet body, formed thereat, for guiding air to the impeller. The present embodiment is advantageous in that a heat dissipation vane is provided on the outer peripheral surface of the inner housing to guide air which passes between the inner housing and the outer housing after being suctioned into the inlet body, and thus when being guided by the heat dissipation vane, the air having been moved by the impeller can efficiently absorb heat transferred from the stator to the heat dissipation vane and more stable flow than when colliding against the stator and the rotor, and thus can be quickly discharged.
