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.
