    • 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.

    • 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.
    • 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。

    • In a shaftless spinning rotor assembly wherein the spinning rotor is the rotor of an axial field motor, an improved transfer of power and improved running properties are attained by forming the stator windings in channels which extend substantially radially in the stator core and are enclosed over at least a portion of their length by magnetically conducting material. As compared with known gap windings, the windings can be placed in multiple layers while at the same time avoiding marked graduations in permeance and in the specific current density so that eddy currents in the rotor can in turn be reduced and rotor heating remains within reasonable limits. The stator is preferably formed of multiple component parts which allows optimized selections of materials.

    • A shaftless spinning rotor for an open-end spinning machine is adapted to operate as a rotor driven by a stator in an axial field motor supported thereon by a combined magnetic and gas bearing producing separate magnetic fields for guiding orientation of the rotational axis of the rotor and for driving rotation thereof which achieves smooth substantially non-oscillating operation with minimal heating in the region of the axis of rotation by interposing a barrier layer with nonmagnetic properties between respective means for conducting the magnetic flux of the driving and guiding magnetic fields for decoupling the magnetic fields.

    • In order to improve the smoothness of operation of a shaftless spinning rotor embodied as the rotor of an axial field motor wherein the rotor is supported by a magnetic gas bearing, a guide magnet arrangement for generating a magnetic guiding field is decoupled mechanically from the drive component of the stator. To that end, separate magnet and stator components are connected to one another by means having both elastic and damping properties, e.g., rubber. This mechanical decoupling makes it possible for the separate components to execute vibration independently of one another and for vibration to be transmitted from one component to another only in highly attenuated form. Hence, machine vibration can substantially be prevented from affecting the smoothness of rotor operation. Tangential forces generated by harmonics and radial forces caused by magnetic or mechanical asymmetries can likewise be absorbed by the stator, with an attendant improvement in smoothness of rotor operation.
    • 为了提高实现为轴向励磁电机的转子的无轴式旋转转子的操作的平滑度,其中转子由磁性气体轴承支撑,用于产生磁性引导场的导向磁体装置与驱动部件机械地分离 的定子。 为此,单独的磁体和定子部件通过具有弹性和阻尼特性的手段彼此连接,例如橡胶。 这种机械解耦使得分离的部件可以彼此独立地执行振动,并且振动只能以高度衰减的形式从一个部件传递到另一个部件。 因此,可以大大防止机器振动影响转子运转的平滑度。 由磁场或机械不对称性引起的谐波和径向力产生的切向力同样可以被定子吸收,从而提高转子运行的平滑度。
