Abstract: According to an embodiment of the disclosure, a motor assembly may include a stator including a coil; a rotor accommodated inside the stator and configured to rotate; first and second housings coupled to first and second sides of the stator; an impeller disposed in a first direction of the first housing and configured to rotate together with the rotor by being coupled to one side of the rotor; a cover having an opening through which air is introduced by rotation of the impeller, and configured to protect the impeller; and a heat dissipation member surrounding at least a portion of an outer surface of the stator and configured to reduce heat generated in the motor assembly as the rotor rotates. Therefore, it is possible to minimize vibration caused by the rotation of the motor, thereby reduce noise, and lower heat generated inside the motor. Other various embodiments are possible.
