Abstract
A fan motor includes: a motor body; a rotary shaft assembly having a rotor and a bearing mounted on a rotary shaft; a stator that surrounds the rotor; an impeller connected to the rotary shaft; and a bracket including a bearing housing portion for receiving the bearing. The bearing housing portion defines a bearing heat dissipating flow path that allows air to be discharged to an outside of the bearing housing portion after passing between the outer surface of the bearing and the bearing housing portion. Air blown from the impeller can absorb heat of the bearing by contacting an outer surface of the bearing while passing through the bearing heat dissipating flow path.
