Abstract
A damping device for the spinning rotor (3) of an open-end spinning device (1). The spinning rotor (3) is fixed radially and axially via a magnet support arrangement (43), supported in a galvanically separated manner as regards the housing of the spinning device (1) and rotates with a high rotary frequency. The damping device (42) converts oscillations occurring especially during the acceleration phase and when passing through the natural frequency range directly into friction losses.
