  • Patent number: 11936260
    Abstract: A stator for an electric machine includes: a laminated stator core including stator grooves and having a plug-in side and a bending side, which bending side lies opposite the plug-in side in an axial direction; a stator winding having hairpin elements which are pushed into the stator grooves on the plug-in side of the laminated stator core and bent and electrically connected to the stator winding on the bending side of the laminated stator core; and an end plate which is arranged on the plug-in side in the axial direction between the laminated stator core and the hairpin elements. The hairpin elements are arranged in the axial direction so as to bear against the end plate.

  • Patent number: 7403730
    Abstract: A printer or copier system with at least one of a pre-processing unit and a post-processing unit, comprises a printing unit that generates a print image on a carrier material. An operating unit is connected via a data line with the printing unit. The operating unit outputs at least one graphical user interface on a display for operation of the printing unit. At least one processing unit is connected with at least one of the printing unit and the operating unit for processing of the carrier material such that data are transferable between the processing unit and at least one of the printing unit and the operating unit. In the processing unit, data are stored that are transferred to at least one of the printing unit and the operating unit with which the graphical user interface is activated at least for operation of the processing unit.
