A slip-ring arrangement (1) for an electrical rotary machine has a rotor (2) and a sliding-contact device (3) which is arranged on the rotor (2) and has a slip ring, and a sliding-contact element with which the slip ring can make electrical contact. Furthermore, a radial fan impeller (4) with an intake device is arranged on the rotor (2), wherein the intake device is designed in such a way that, during operation of the radial fan impeller (4), a cooling fluid can be drawn into the radial fan impeller (4) through the intake device along the sliding-contact device (3). Furthermore, the slip-ring arrangement (1) has a spiral housing (10) which is of spiral design and surrounds a radial circumference of the radial fan impeller (4). |
