  • Patent number: 8823239
    Abstract: The invention relates to an electrical machine (8), in particular an electric motor, suitable for the adjustment by external force of elements of a motor vehicle, essentially for driving a steering booster. The inventive electrical machine comprises a rotor (7) and a shaft (10), the rotor having a plurality of plates (5), wherein the plates (5) are premounted on the shaft either individually or as a plate assembly (6) or by means of a plurality of plate assemblies (6), the rotor (7) being connected to the shaft (10). The plates (5) have resilient lugs (3) for fixing the plates (5) and/or plate assemblies (6) to the shaft (10). Furthermore, the plates (5) of the plate assemblies (6) comprise centering lugs (1) which serve to radially center the plate assembly (6) relative to the shaft (10).

  • Patent number: 7770280
    Abstract: A method for manufacturing multiphase windings (32) of an electric machine provides the following process steps: Cross-sectional profiles (13) that increase the slot space factor are stamped onto wire elements (7, 11, 12). Offsetting dies (14, 26) are loaded with stamped wire elements (7) to constitute the winding (32), stamped wire elements (11) to constitute an integrated star point (21), and stamped wire elements (12) for supplying current to the winding (32). The offsetting dies (14, 26) offset the stamped wire elements (7, 11, 12) in their end regions. An interconnection of the integrated star point (21) is produced by thermally attaching (30) the stamped wire elements (11) for the integrated star point (21) to a connecting ring (40) on an inside (41) of a finished winding head (20).

  • Patent number: 6834630
    Abstract: The invention relates to a starter system for an internal combustion engine, in particular in motor vehicles, having a starter motor, a reduction gear, and a pinion-engaging assembly. The primary components of the starter system (10) are embodied as individual modules and can be expanded in variable ways to make starter systems (10) with different parameters.

  • Publication number: 20040251769
    Abstract: An electrical machine, in particular a starter for motor vehicles, with a stator (36) and a rotor (39) is proposed; the rotor has a hollow shaft (63) with various shaft segments. The electrical machine is characterized in that the shaft (63), between a bearing seat (81) and a shaft segment contour (108) for transmitting a torque, is a one-piece tube.

  • Patent number: 6643912
    Abstract: The invention relates to a method for producing a commutator ring (10) for a commutator of an electrical machine, in which the laminas (12) of the commutator ring and fastening means (18) are formed out of a band material (27), and a selectable number of laminas (12) are then closed to form the commutator ring. The fastening means are produced with a special tool (35) in the form of dovetail grooves (22) by means of a so-called furrowing operation, which is done simultaneously from both face ends of the laminas (12).

  • Patent number: 5602438
    Abstract: A roll commutator for electric motors has a plurality of bars adjacent to one another and produced from a continuous metal section. The metal section already has projections on one of its sides before the production of the bars, which projections serve as anchoring claws after rolling up the line portions produced from the metal section. Additional tools and processing steps are not needed since it is not necessary to process the claws when manufacturing the roll commutator.
