摘要：
An OE spinning apparatus 1 with a spinning rotor 2 having a hollow shaft 26 supported radially in a wedge-like gap 25 of a support-disk bearing 4 and driven by an individual motor 9 comprising an armature 11 integrated into hollow shaft 26 at its end and a stator 10 fixed to spinning-box housing 12. Pressure roller 8 rotates about axis 24 angled acutely to rotor shaft 3 to urge rotor shaft 3 into the gap 25 and also in the direction of axial bearing 13, which may be a permanent magnet bearing or pneumatic bearing. Spinning apparatus 1 thereby has a high natural frequency, which makes possible very high rotor speeds.
