Abstract: An electric motor-and-gear assembly for driving vehicle aggregates such as windshield and rear window wipers, power-window units and the like, having a transmission housing that can be closed by a housing cover. A motor housing that contains a commutator motor whose commutator protrudes into the transmission housing and cooperates with a brush holder fixed in the transmission housing. For the sake of a more reasonably priced manufacture and a time-saving, more rapid assembly of the brush holder, the commutator brushes are embodied as hammer brushes with spring leaf actuators prestressed toward the commutator. The spring leaf actuator are respectively fixed with their one actuator end in a U-shaped plastic carrying part of the brush holder, which is inserted into the transmission housing radial to the commutator, through the housing opening and is positioned in the transmission housing in a positively engaging manner by means of the housing cover.

The electric drive unit includes electrical components of an electronic system for the motor. To reduce production costs and simplify assembly, the electrical components are electrically secured to a lead frame that makes the electrical connection between the components and the commutator motor and the commutator brushes are embodied as hammerhead brushes, whose carrier plates are bent in one piece out of the lead frame.

Abstract: An electric drive unit having an electric drive motor and a transmission. The electric drive motor has an armature shaft which extends, for example, to a worm shaft of the transmission. The shaft is embodied of one piece with the armature shaft. A first bearing and a second bearing are provided to support the armature shaft. The second bearing is embodied as a ball bearing with an outer ring, an inner ring, and balls. The inner ring is press-fitted in a rotationally fixed manner onto the armature shaft. The outer ring is slid into a receiving bore disposed in the transmission housing and is pressed against an axial stop face adjoining the receiving bore by means of a retaining part that is supported in an installation channel and has flexible tongues that are directed toward the outer ring. This axial pressing can be produced in an easy-to-assemble fashion and is also inexpensive thanks to a low cost of the retaining part.

Abstract: A method of balancing an electronically driven air blower unit comprising a radial blower with a high-speed electronically commutated d.c. motor which drives the blower and which is of external rotor design, utilizing a balancing device into which the completely mounted air blower unit (1) can be inserted, without housing lid, and with which electrical contact (101, 102, 103; 201, 202, 203) can be made. The balancing device is provided with a control device for the motor (3, 4, 5) of the air blower unit and with a device (9) for bridging the motor electronics (10) of the air blower unit (1) itself. In order to drive the part to balanced of the air blower unit, its electromechanical transducer (3, 4, 5) is used, which for this purpose is actuated by the control device provided in the balancing device. The balancing process is essentially carried out in two compensation planes which are spaced axially from one another and are parallel with one another.
