Abstract: A method and a system for supporting the planning and design of manufacturing systems are described. In addition, an electronic unit and a computer program as well as a computer program product for carrying out the method are described. In the described method, the manufacturing system is represented as a digital model containing objects. This digital model is embedded in a simulation environment (80) for an analysis.

Abstract: An electric motor, particularly a windshield-wiper motor for a motor vehicle. In order to be able to insert an armature-shaft bearing into an inaccessible bearing seat in a housing of the electric motor, the armature-shaft bearing is fixed axially in position in the bearing seat by a detent element. This makes it possible to insert the armature-shaft bearing, mounted on the armature shaft, together with the armature into the bearing seat.

Abstract: In rotors for electric motors, it is usual to fix the commutator on the rotor shaft by means of a press fit. In the present invention, the rotor shaft, with the rotor core fixed thereon, is electronically coated with an epoxy layer on opposite portions of the rotor shaft and in the winding slots, and is then heated on the plasticizing and curing temperature of the epoxy. After that, with the help of a sliding temperature, the commutator, whose inner bore has a clearance fit relative to the rotor shaft, is slipped onto the rotor shaft in a terminal position, in the process the still-viscous epoxy is pushed backward and is deposited radially on a connecting end face, forming a bead, and penetrates the annular gap between the inner bore and the rotor shaft. Once the epoxy layer has cooled, the commutator is fixed against rotation and displacement on the rotor shaft. The rotor is suitable for electric motors of various types.

Abstract: A rotor for a commutator machine, having a rotor shaft, a rotor body containing a rotor winding, and a commutator, which has an insulation material body non-rotatably supported on the rotor shaft and has a number of commutator lamellas that are disposed on the insulation material body. Connection lugs that are bent away from the commutator lamellas for connecting connection wires of the rotor winding, in order to use the advantageous ultrasonic torsion welding process to mechanically and electrically connect connection lugs and connection wires without changing the rotor geometry, the insulation material body, is axially supported against the end face of the rotor body oriented toward the end face.

Abstract: In rotors for electric motors, it is usual to fix the commutator on the rotor shaft by means of a press fit. In the process, damage undesirably occurs to the surface of the rotor shaft.

Abstract: In rotors for electric motors, it is usual to fix the commutator on the rotor shaft by a press fit. In the present invention, the rotor shaft, with the rotor core fixed thereon, is electrostatically coated with an epoxy layer on opposite portions of the rotor shaft and in the winding slots, and is then heated to the plasticizing and curing temperature of the epoxy. After that, by a sliding tool, the commutator, whose inner bore has a clearance fit relative to the rotor shaft, is slipped onto the rotor shaft in a terminal position, in the process the still-viscous epoxy is pushed backward and is deposited radially on a connecting end face, forming a bead, and penetrates the annular gap between the inner bore and the rotor shaft. Once the epoxy layer has cooled, the commutator is fixed against rotation and displacement on the rotor shaft. The rotor is suitable for electric motors of various types.

Abstract: An electric motor, including at least two permanent magnet segments disposed around a motor longitudinal axis, in which each permanent magnet segment has end faces extending in the direction of the motor longitudinal axis and is encompassed by two independent yoke ring segments that have a gap between them parallel to a symmetry plane extending through the motor longitudinal axis and the center of the permanent magnet segments in order to reduce the armature transverse field. In addition to the reduction of the armature transverse field, a weight reduction of the electric motor is also achieved. To this end, in a first region close to the end faces of the permanent magnet segments, the one-piece magnetically conductive yoke is provided with a larger cross section than in a second region close to the symmetry plane extending through the center of the permanent magnet segments. The construction is particularly suited for small electric motors, in particular d.c. motors that are excited by permanent magnets.

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.
