An external rotor motor is disclosed, which features a stator (11) and a rotor (13) surrounding the stator (11) while leaving an air gap. A damper (16) made of an elastic material is arranged on the outside of the rotor (13) in order to dampen resonant rises in airborne sound, which is emitted by the rotor of the external rotor motor and by an aggregate coupled to it. In the case of a rotor (13) that is designed to be pot-shaped, the damper (16) is preferably embodied as a damping cap (17), which surrounds the pot jacket (132) and at least partially covers the pot base (131) (FIG. 1).
