Patent number: 7479725Abstract: The stator for an electric machine includes a ring-shaped stator yoke, on which stator coils, formed on winding bodies and distributed uniformly around the circumference, are mounted. The coils are wired electrically together by a wiring arrangement, which has a ring-shaped carrier element designed to be attached to the stator to hold connecting conductors. The carrier element is mounted radially with respect to the winding elements. To ensure a simple and reliable mounting of the carrier element on the stator, it is proposed that the carrier element be held in place on the winding bodies by means of a latching connection so that it cannot move in the axial direction.Type: GrantFiled: October 24, 2006Date of Patent: January 20, 2009Assignee: ZF Friedrichshafen AGInventors: Knut Welke, Manfred Zimmer

Patent number: 7472768Abstract: A drive system which has a drive unit with a drive shaft; a centrifugal mass arrangement, which is mounted on the drive shaft; and an electrical machine, comprising a stator arrangement and a rotor arrangement, where the rotor arrangement is mounted on the centrifugal mass arrangement, and where the stator arrangement and the rotor arrangement are adjacent to each other in the radial direction. So that optimum use can be made of the space available inside the drive unit, and so that the overall length of the drive unit required in the axial direction relative to the axis of rotation (A) can be kept as short as possible, the centrifugal mass arrangement has a contour such that, relative to the axis of rotation (A), a receiving space (71) is formed radially inside the electrical machine. The receiving space is bounded on at least one side by the centrifugal mass arrangement, and at least one additional component of the drive unit is installed in the receiving space.Type: GrantFiled: November 29, 2006Date of Patent: January 6, 2009Assignee: ZF Sachs AGInventors: Armin Denner, Knut Welke, Klaus Steinel, Joachim Lindner, Frank Hirschmann
