Abstract

The invention discloses an air duct assembly of a motor and the motor with the air duct assembly. The air duct assembly comprises a case, a middle shaft part, a fan cover, a rotor and an impeller, wherein the case comprises a body; the middle shaft part is arranged at the upper end of the body; a first through hole is formed in the middle shaft part; the fan cover is arranged at the upper part ofthe body and is in clearance fit with the body; a first chamber is defined by the fan cover and the body; a first step surface is arranged at the lower part of the fan cover; the upper end of the bodyis propped against the first step surface; the rotor is accommodated into the first chamber; the rotor is rotationally connected to the inside of the first through hole; the impeller is arranged in the first chamber; a second through hole is formed in the impeller; and the impeller sleeves the middle shaft part through the second through hole. According to the air duct assembly of the motor disclosed by the embodiment of the invention, a predetermined clearance is kept between the upper part of the fan cover and the impeller, and the lower part of the fan cover is connected with a peripheralwall of the body in a matched manner, so that positioning in the axial direction is accurate, assembly operation is convenient and fast and the condition that the work efficiency of a fan does not easily change is ensured.
