  • Stator for an electrical machine
    Patent number: 7365460
    Abstract: In a plurality of stator coils arranged on the yoke, each coil has a pair of ends, each end being adjacent to a respective end of an adjacent coil to form pairs of adjacent ends. A plurality of mutually insulated concentrically arranged linking conductors each has a plurality of circumferentially arranged terminal elements, each terminal element being electrically connected to a respective pair of adjacent ends to form a contact area in a common axial and radial position.
    Type: Grant
    Filed: March 16, 2006
    Date of Patent: April 29, 2008
    Assignee: ZF Friedrichshafen AG
    Inventors: Werner Herlet, Hubertus Büttner, Michael Fister, Bernhard Schmitt, Marcus van Heyden, Alfons Vollmuth, Manfred Röder, Khalid Jafoui, Jens Baumeister, Knut Welke

  • Systems and methods for communicating with or providing power to an implantable stimulator
    Publication number: 20050119716
    Abstract: An exemplary system for communicating with or providing power to an implantable stimulator includes a coil configured to emit a magnetic field for driving a corresponding circuit in the implantable stimulator and a coil driver circuit configured to drive the coil with a tuning frequency. The coil driver circuit actively adjusts the tuning frequency such that the coil operates at a frequency substantially equal to a resonant frequency. An exemplary method of communicating with or providing power to an implantable stimulator includes driving a coil with a tuning frequency and actively adjusting the tuning frequency such that the coil operates at a frequency substantially equal to a resonant frequency. The coil emits a magnetic field used to drive a corresponding circuit in the implantable stimulator.
