Abstract
A bearing and drive structure for the funnel-shaped spinning element of an open-end spinning turbine, composed of a stator with a projecting portion carrying an elastically mounted bearing and a rotor with a cup-shaped portion into which the projecting portion of the stator extends, the rotor being carried by the bearing and having its center of gravity at least approximately in the region defined between the axial ends of the flexible bearing, the stator carrying electrical windings cooperating with the cup-shaped rotor portion to form an electrical drive for the rotor.
