    摘要: A cylinder for guiding yarn comprises a hollow-cylindrical jacket seated on a support by radially acting magnetic bearings having plural pole windings distributed circumferentially. The cylinder jacket position is detected by plural sensors coupled with the pole windings by a control unit. The sensors are spaced from the cylinder jacket and from the support for determining the actual position of the cylinder jacket relative to a stationary reference position. Vibrations of the cylinder jacket are damped by determining the actual position of the cylinder jacket in relation to a stationary reference position and the chronological change of the actual position as a function of the rotary frequency of the cylinder jacket. Control signals for the magnetic bearing are generated to cause the magnetic bearing to counteract the position change of the cylinder jacket.
