Abstract
A fan motor includes a housing, a rotating shaft that is rotatably disposed in the housing and extends through the housing, an impeller rotatably disposed at the rotating shaft, a first vane disposed adjacent to the impeller and configured to guide a flow of air generated by the impeller, a rotor disposed at the rotating shaft and spaced apart from the impeller in an axial direction of the rotating shaft, a stator that is disposed in the housing and surrounds the rotor, the stator and the rotor defining an air gap therebetween, and a second vane coupled to the stator and disposed downstream relative to the first vane in a flow direction of the flow of air. The second vane is in contact with at least a part of an inner surface of the housing.
