ABSTRACT:
An electric motor (1) has a stator (3) and a rotor (5) having a rotor shaft (7), which rotor shaft is supported relative to the stator by means of ball-bearings (9). The ball-bearings are connected directly to suspension elements (11 ) for the suspension of the electric motor (1) relative to an external device. Resilient elements (13) are arranged between the suspension elements (11) and the stator (3) to suppress vibrations in the suspension elements (11). When the electric motor (1) is used in an apparatus less vibrations are transmitted to the frame of the apparatus, so that the apparatus itself also produces less vibrations and less noise.
