Patent number: 9966819Abstract: The invention relates to an electric machine (10) which is embodied as an alternator, comprising a rotor (20) and an axis of rotation (183), a stator iron (17) which maintains a stator winding (18). Said stator winding (18) comprises phase terminals of winding wires (204), a rectifier circuit (151) which comprises at least one bridge circuit consisting of a positive diode (99) and a negative diode (58). Said positive diode (99) and the negative diode (58) are connected in an electrically conductive manner to the phase terminal of winding wires (204) by means of a metal connecting element (133, 146) which has two half arms (215). One half arm (215) is connected in an electrically conductive manner to a positive diode (99) by means of a connecting section (216) and another half arm (215) is connected in an electrically conductive manner to the negative diode (58) by means of another connecting section.Type: GrantFiled: July 11, 2013Date of Patent: May 8, 2018Assignee: SEG Automotive Germany GmbHInventors: Ruediger Schroth, Klaus Herbold, Gianna Rivera-Schlottbohm, Vassilios Sekertzis
