摘要： A rotor spinning machine includes a plurality of work stations arranged side by side between two front-side ends along at least one longitudinal side of the machine. Each work station includes work elements for producing and winding a yarn, such as a feed device, an opening device, a spinning rotor, and a winding device. A suction device provides a negative spinning pressure at the work stations and includes a negative pressure source arranged at each of the two front-side ends of the rotor spinning machine. Each negative pressure source is connected to a separate negative pressure channel that extends in a longitudinal direction of the rotor spinning machine only over a part of a total number of the work stations. Each work station includes an individual drive for the spinning rotor.

摘要： A method and an apparatus for operating an open-end spinning unit, which comprises a spinning rotor 1 that rotates during the spinning operation at a high rotational speed in a closed rotor housing 2. The spinning rotor is rotated by an individual electric motor drive 18 and supported in a smoothly running bearing assembly. When the drive is disconnected and the rotor housing is properly closed by a cover element 8, the spinning rotor is biased and rotated by an airflow resulting from a vacuum prevailing in the rotor housing and the motor drive operates as a generator. At least one of the electric quantities Pv, Gv which develop during the generator operation of the drive 18 is monitored, and upon exceeding a threshold value which can only be attained when the cover element is properly closed, a signal S is generated and processed in a control unit 30 to cause the cover element 8 on the rotor housing 2 to be locked, and thereafter the drive 18 of the spinning rotor 3 is released for a restart.

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.

摘要： A single-motor drive for an open-end spinning machine, the motor being in the form of an axial field motor with a magnet/gas bearing supporting the rotor with a gas cushion, includes a gas monitoring arrangement which will detect a disruption in the gas supply, and responsive to the gas disruption, a device for braking the rotor is connected with the circuit via a switch. The braking device, which includes a ballast resistor, is set for reducing the rotational speed of the rotor in a manner whereby when the rotor bearing surface lands on the stator bearing surface due to the collapse of the air cushion, its rotational speed is less than that which would result in damage to the bearing surfaces.

摘要： A drive for a shaftless spinning rotor wherein the spinning rotor is embodied as the rotor of an axial field motor utilizes axially opposed yoke-forming, magnetically conductive elements disposed respectively on the opposite sides of an air gap formed between the spinning rotor and the stator in combination with at least one magnet (preferably either permanent magnets or electromagnets) on one or both the rotor and stator arranged concentrically to one another and to the rotor axis. The present magnet/yoke arrangement does not require exact mutual alignment of oppositely located magnets nor their homogeneous polarization. The present arrangement is self-adjusting because of the generation of a point-symmetrical field which in operation forms a sort of magnetic potential depression. Magnetic drive and guide fields are advantageously decoupled in order to reduce their mutual interference.
摘要翻译：一种无轴式旋转转子的驱动装置，其中旋转转子被实施为轴向励磁电动机的转子，其利用轴向相对的磁轭形成导磁元件分别设置在形成在旋转转子和定子之间的空气间隙的相对侧上与至少一个磁体（优选地是永磁体或电磁体）组合在一起或两个转子和定子上，彼此同心地布置并转动到转子轴线。本磁体/磁轭装置不需要相对定位的磁体的精确相互对准，也不需要它们均匀的极化。由于产生了一个点对称场，所以这种布置是自调整的，这在操作中形成一种磁势抑制。为了减少它们的相互干扰，磁驱动和引导场有利地被去耦合。

摘要： In an open-end rotor spinning apparatus, the driven rotor shaft (2) of the spinning rotor (1) is mounted by means of bearing members (20) for rotation in a casing (3) which is inserted into a mounting on the machine. The replacement of the spinning rotor (1) together with the bearing casing (3), without exerting a load on the bearings, is made possible by a flange (60) which is disposed on the bearing casing (3) and which extends along the rear side of the spinning rotor (1) and projects at least over the major diameter of the spinning rotor. During replacement of the rotor, the flange (60) serves as a handle, and in normal operation it serves as an additional cooling means for the bearings. By means of a ring (61) mounted on the flange (60), it is possible to form a casing (6) which is open at the front and which, with slight clearance, surrounds the outside contour of the spinning rotor (1) and reduces the consumption of energy.
