Abstract: An electric motor assembly includes an impeller, a guide vane disposed at a one side of the impeller along an axial direction, a stator disposed at one side of the guide vane along the axial direction, a rotor configured to rotate relative to the stator to thereby rotate the impeller, and a frame disposed at an outside of the stator in a radial direction and coupled to the stator. The frame includes a body that has a cylindrical shape, that is disposed at the outside of the stator, and that defines an air flow path, and a plurality of stator fixing parts that protrude from an inner surface of the body and are coupled to the stator. The plurality of stator fixing parts are inclined with respect to the axial direction.
