Abstract
A rotor spinning device with a contactless passive radial bearing for the spinning rotor. A damping device exerts magnetic forces on the rotor shaft ( ) of the spinning rotor by means of operating elements ( ), and in this manner damps radially directed oscillations of the spinning rotor. The stationary operating elements ( ), which are embodied as magnetic elements, act directly on a magnetic element ( ), which is fixedly connected with the rotor shaft ( ), wherein the magnetic element ( ) is an operative element of the passive bearing of the spinning rotor. A rapid, effective damping of the oscillations is possible without large expenditures.
