In an electrical drive mechanism, in particular for motor vehicles, having a commutator motor ( ) disposed in a housing ( ), which commutator motor ( ) has a rotor shaft ( ) with a commutator ( ) non-rotatably supported on it and has a brush holder ( ) affixed to the housing ( ), and having a bearing ( ) disposed in the vicinity of the commutator ( ), which bearing has a bearing bush ( ) that encloses the rotor shaft ( ) with rotary play and a bearing seat ( ) that contains the bearing bush ( ), in order to achieve a simple embodiment for the bearing ( ), a clamping member ( ) is formed onto the brush holder ( ) of one piece with it, which clamps the bearing bush ( ) in a frictionally engaged, axial fashion in the bearing seat ( ) formed in the housing ( ) (FIG. ).

Electric drive, especially for motor vehicles

The invention relates to a method for producing a shaft ( ), and an apparatus containing such a shaft ( ), in particular an armature shaft ( ) of an electric motor-driven drive ( ) that is brought to a nominal dimension ( ). The shaft ( ) is reshaped by means of material displacement ( ) at least one point until the nominal dimension ( ) is reached.

Method for producing a shaft and a device containing a shaft of this type

An armature of the invention has a component, to be mounted on the shaft, that has a protrusion in the internal diameter; the protrusion engages a knurled feature on the shaft, and the initial stresses can lessen at least in part over the course of time.

Armature for an electric machine

An electric motor drive mechanism, in particular a window control drive mechanism for a motor vehicle, has an electric motor ( ), which has a motor armature shaft ( ) that is operatively connected to a gear unit ( ) surrounded by a gear housing ( ), and also has a motor electronics unit ( ) surrounded by an electronic housing ( ). The electronics housing ( ) has a guide rail ( ), extending radially to the motor armature shaft ( ), for insertion of the electronics housing ( ) via a counterpart guide ( ) disposed on the gear housing ( ).
