Wolfgang Harrer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Strip-type segment and laminated stator core for an electrical machine
    Patent number: 7705510
    Abstract: A striplike lamination (10) for a stator of an electrical machine is proposed, in which the striplike lamination has an end contour (19) on each strip end (18). The end contours (19) are embodied such that a difference in length at the lamination (10) resulting from bending can be compensated for.
    Type: Grant
    Filed: July 30, 2003
    Date of Patent: April 27, 2010
    Assignee: Robert Bosch GmbH
    Inventors: Klaus Pflueger, Martin Henne, Thomas Berger, Erberhard Rau, Wolfgang Harrer
  • Stator for an electrical machine
    Patent number: 7282830
    Abstract: A stator for an electrical machine is proposed that has a stator winding (45) that is held by a stator core (10) that is formed into an annular shape. The stator core (10) has grooves (14) and teeth (13) on its radially inwardly oriented circumference. The stator core (10) is composed of layered stator sheet metal lamellae (11), the direction of the layers defining an axial direction (a). It is provided that at least a first stator sheet metal lamella (20) has a higher flexural strength than second stator sheet metal lamellae (21), the at least one first stator sheet metal lamella (20) having a thickness (dLE) in the axial direction (a) that does not exceed 4 mm.

  • Strip-shaped lamina and laminated stator core for an electric machine
    Patent number: 7129614
    Abstract: A strip-shaped lamella (10) for a stator (30) of an electric machine, having a yoke region (12) and a number of first teeth (18) that are of one piece with the yoke region (12) on a first side (14) and have first grooves (20) between them, and having second teeth (22) that are of one piece with the yoke region (12) on a second side (16) oriented away from the first side (14) and have second grooves (24) between them. The second teeth (22) are located at a position of the first teeth (18).
