    摘要： A motor is provided. The motor according to an aspect of the present disclosure comprises a housing, a bearing disposed in the housing, a rotating shaft rotatably coupled to the bearing, an impeller cover disposed on an upper part of the housing, an impeller disposed inside the impeller cover and coupled to the rotating shaft, a magnet coupled to a lower area of the rotating shaft, a stator coupled to the housing and facing the magnet, and a coil wound around the stator. In this case, the impeller includes a body, a plurality of blades formed on an outer peripheral surface of the body, a plurality of grooves concavely formed upward from a lower surface of the body, and a coupling hole formed in a central area of the body and in which the rotating shaft is disposed.
