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.
Claims20
An electric motor assembly, comprising:
- an impeller;
- a guide vane disposed at a first side of the impeller along an axial direction, the guide vane comprising a plurality of vanes;
- 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,
- wherein the frame comprises:
- a body having a cylindrical shape, the body being disposed at the outside of the stator and defining an air flow path, and
- a plurality of stator fixing parts that protrude from an inner surface of the body in the radial direction and are coupled to the stator, and
- wherein the plurality of stator fixing parts are inclined with respect to the axial direction,
- wherein the plurality of vanes are inclined with respect to the axial direction,
- wherein an inclination direction of the plurality of stator fixing parts with respect to the axial direction is substantially equal to an inclination direction of the plurality of vanes with respect to the axial direction, and
- wherein each of the plurality of stator fixing parts has a first side surface and a second side surface that face a circumferential direction of the body and are inclined with respect to the axial direction.
