Patent number: 11349364Abstract: A stator of an electrical machine which has stator slots and conductor elements arranged in the stator slots, which conductor elements each have two conductor ends, is already known. A plurality of conductor ends, which are situated next to one another, of different conductor elements are in each case connected to one another by means of a weld connection, which is provided at the end sides of the conductor ends in question, without additional material. The conductor ends which are connected to one another in each case form a common rectangular conductor cross section which has a height H and a width B, wherein the height H corresponds to the height h of an individual cross section of the conductor ends, and the width B of the common conductor cross section is made up of the sum of the widths b of the individual cross sections of the conductor ends. The weld connection is in each case provided, as seen in the direction of the width B, between two non-melted edge sections of the outermost conductor ends.Type: GrantFiled: May 11, 2017Date of Patent: May 31, 2022Assignee: Robert Bosch GmbHInventors: Tobias Hein, Fabian Lange, Patrick Priebe, Stefan Ossenkopp

Patent number: 8823239Abstract: 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).Type: GrantFiled: January 24, 2008Date of Patent: September 2, 2014Assignee: Robert Bosch GmbHInventors: Stefan Ossenkopp, Joachim Becker, Holger Klatte, Erik Maurer, Ngoc-Thach Nguyen, Stefan Stoermer, Bruno Holzwarth, Tilo Koenig

Patent number: 7770280Abstract: 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).Type: GrantFiled: February 9, 2004Date of Patent: August 10, 2010Assignee: Robert Bosch GmbHInventors: Stefan Ossenkopp, Martin Ermer

Patent number: 6643912Abstract: 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).Type: GrantFiled: June 25, 2001Date of Patent: November 11, 2003Assignee: Robert Bosch GmbHInventors: Friedrich Behrens, Hans Deierling, Stefan Ossenkopp, Martin Schwerdtle

Patent number: 5602438Abstract: 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.Type: GrantFiled: October 24, 1995Date of Patent: February 11, 1997Assignee: Robert Bosch GmbHInventors: Ludwig Reisnecker, Martin Schwertle, Winfried Brettmann, Friedrich Behrens, Hans Deierling, Peter Franz, Siegfried Hauptmann, Claus Pollack, Stefan Ossenkopp
