ABSTRACT:
The controlled magnetic bearing arrangement supports a rotatable shaft and contains an electronic control circuit. The shaft is floatingly supported in the bearing arrangement by magnets controlled by the electronic control circuit and the stiffness of the shaft is thereby adjustable. The shaft may constitute a package support shaft in a winding device of a spinning machine and has a free end for permitting the axial exchange of bobbin tubes and packages. This arrangement provides the advantages of attaining very high rotational speeds for the package support shaft and the possibility of varying the stiffness of such package support shaft and thus the critical rotational speeds. The regions of the critical rotational speeds can be passed through in a safe manner.
