    Abstract: A motor assembly comprises a stator, a rotor configured to be rotated about a shaft by electromagnetically interacting with the stator, an impeller configured to be rotated with the rotor about the shaft by being coupled to the rotor and configured to suction air in response to a rotation, a housing configured to cover between the impeller and the stator by being coupled to the stator, a cover comprising an inlet through which air sucked by the impeller is introduced, and configured to cover the impeller, a guide member configured to guide the air discharged from the impeller and configured to be coupled to the housing, and a plurality of first vanes protruding from one of the cover and the guide member to an axial direction and coupled to the other of the cover and the guide member. The cover and the guide member are configured to be movable in the axial direction in response to not being coupled to the housing, and the cover comprises a contact portion in contact with the impeller according to a position of the cover. The contact portion is spaced apart from the impeller in response to coupling between the guide member and the housing.
