Patent attributes
A fan motor is provided that includes an inner housing having an inner space formed therein; a rotational shaft assembly supported in the inner housing and having a rotor and a bearing mounted on a rotational shaft thereof; a stator disposed to surround the rotor in the inner housing; an impeller connected to the rotational shaft; and an outer housing that surrounds an outer periphery of the inner housing and having an inlet body that guides air to the impeller. At least one heat dissipation vane is provided on an 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 at least one heat dissipation vane, the air having been moved by the impeller may efficiently absorb heat transferred from the stator to the at least one heat dissipation vane and more stably flow than when colliding against the stator and the rotor, and thus, may be quickly discharged.
