Abstract: A fan motor may include a motor housing that guides a flow of air generated by an impeller. The motor housing may include an outer wall, and an inner wall disposed inside of the outer wall and spaced apart from the outer wall. The motor housing may include at least one vane that extends between the outer wall and the inner wall to guide the flow of air. The motor housing may further include at least one vane extension portion that extends from a downstream end of the at least one vane to cover at least a portion of a thickness surface of the inner wall. With this structure, the at least one vane extension portion may improve a cooling performance of the motor while minimizing flow loss due to a vortex generated while some of the air flowing along a flow path flows to a motor accommodating portion.
