Abstract
An electro-motor drive, in particular for a fan drive of a motor vehicle, includes a commutator motor, a motor shaft of which is rotatably mounted on axially opposite sides in shaft bearings facing away from the bearing shield in order to substantially dampen the sound of at least bearing play-related contact noise and vibration or humming noise.
Claims2
An electric motor drive comprising:
- a commutator motor whose motor shaft is rotatably supported on axially opposite sides in shaft bearings that are each covered by an end plate;
- and
- a damping system for sound damping of bearing-play-related impact noises and operation-related whining noises is arranged on a bearing side facing away from the end plate of the shaft bearing,
- wherein the damping system has a sealing disk, which is axially movable on the motor shaft, and a sliding disk that faces the shaft bearings, and
- wherein the sealing disk and the sliding disk are slotted together.
