  • Slip-ring arrangement with spiral fan
    Patent number: 10355562
    Abstract: A slip-ring arrangement for an electrical rotary machine has a rotor and a sliding-contact device which is arranged on the rotor and has a slip ring, and a sliding-contact element with which the slip ring can make electrical contact. Furthermore, a radial fan impeller with an intake device is arranged on the rotor, wherein the intake device is designed in such a way that, during operation of the radial fan impeller, a cooling fluid can be drawn into the radial fan impeller through the intake device along the sliding-contact device. Furthermore, the slip-ring arrangement has a spiral housing which is of spiral design and surrounds a radial circumference of the radial fan impeller.
