Abstract: A motor includes: an inner housing defining an accommodation space, an outer housing defining a flow path with the inner housing, an impeller disposed at a first side of the inner housing, a power portion that is disposed in the accommodation space and that includes a rotation shaft coupled to the impeller so as to be rotated together with the impeller, a bracket coupled to the inner housing at a second side of the inner housing and rotatably supporting the rotation shaft, and a printed circuit board (PCB) that is spaced apart from the bracket by a predetermined distance and that is electrically connected to the power portion. A circumference of the PCB includes a plurality of concave portions that are spaced apart from each other, and the plurality of concave portions are recessed toward a center of the PCB.

Abstract: An electric motor assembly includes an outer housing with two sides open, an impeller provided in the outer housing, an inner housing disposed concentrically in the outer housing and spaced apart from the impeller, a stator provided in the inner housing, a rotor rotatably disposed in the stator, a first air flow path through which air flows in an axial direction between the inner housing and the outer housing based on rotation of the impeller, and a second air flow path through which air is joined with the air of the first air flow path via an inside of the inner housing and a gap between the impeller and the inner housing based on rotation of the impeller. Accordingly, cooling of the stator can be facilitated by the air flow paths.
