Abstract:
The invention relates to an electromotive drive comprising an electric motor with a commutator that is located in a motor housing, in addition to gearing that is flange-mounted on the electric motor. In the drive, the armature shaft passes through an opening into the interior chamber of a gearing housing. A screening element is fixed onto the shaft to rotate with the latter.
