Abstract
In a bearing and drive structure for the spinning rotor of an open-end spinning turbine in which the rotor is carried by an elastically mounted bearing, the structure including a stator having a portion disposed adjacent a portion of the stator; the stator and rotor portions together defining an electrical drive for the spinning rotor and being separated from one another by a motor air gap, the rotation of the rotor is stabilized by the provision of mutually facing, circumferentially extending surfaces on, respectively, the rotor and a stationary body adjacent the rotor and forming a stabilizing air gap smaller than the motor air gap.
