摘要： A magnetic bearing device (1) with an improved vacuum-tight electrical feedthrough through its housing (10) is disclosed. The feedthrough (30) comprises a flat connection element (31 ) such as a rigid or flexible printed circuit board extending through the wall of the housing (10), preferably all the way along an inner circumference of the housing. The connection element is sealed in a gas-tight manner to the housing. The element preferably has a central opening (36) for receiving the rotor shaft. Connections to the bearing units and sensors may be achieved by flat-ribbon cables (51 ) or flexprints. The sensors are preferably also implemented as printed sensors. Thus a very compact and cost-efficient magnetic bearing device can be obtained. An alternative embodiment uses a connection element on a side wall of the housing as a feedthrough to the bearing components.

摘要： A rotor shaft (200) for a magnetic bearing device (1 ) is disclosed. The shaft comprises an inner portion on whose periphery a plurality of targets (240, 260, 280) separated by spacers (250, 270) are mounted. This is achieved exerting an axial pressing force (F, F’) to the peripheral parts, rather than applying a radial press fit. In this manner, a simplified construction, a higher stiffness and a higher stability at high rotational speed are achieved. Further disclosed is a rotor having a thrust disk (220) whose diameter decreases towards the periphery. This allows to use a larger thrust disk at a given rotational speed.

摘要： In a magnetic bearing device in which a rotor is supported for rotation, recovery after a touchdown in the touchdown bearings during rotation is improved by providing, in addition to a basic controller module (220), an impact recovery controller module (240) that delivers control signals specifically adapted to control the rotor position in a touchdown situation. The recovery controller module (240) takes rotor dynamics into account. In particular, this module may act to damp a whirling motion of the rotor. The output signals of the two controller modules are combined by a weighting module (290) in a weighted manner according to a weight factor that indicates occurrence of a touchdown situation.

摘要： A method and a controller for controlling a magnetic bearing device, in which a rotor is suspended for rotation around a shaft, are disclosed. Sensor signals are transformed to yield tilt displacement signals (Sθx, Sθy) which correspond to tilting displacements of the shaft in predetermined directions (x, y). From the tilt displacement signals (Sθx, Sθy), tilt control signals (Aθx, Aθy) are derived; these are transformed to yield actuator control signals for driving electromagnetic actuators in the magnetic bearing device. According to the invention, tilting displacements for which the tilt vector rotates about the device axis (z) with a first predetermined sense of rotation are controlled separately from tilting displacements for which the tilt direction vector rotates about the device axis (z) with a second sense of rotation opposite to the first predetermined sense of rotation. In this way, control of nutation and precession can be achieved without influence from blade vibrations or shaft bending modes.
摘要翻译：公开了一种用于控制磁轴承装置的方法和控制器，其中转子悬挂以围绕轴旋转。传感器信号被变换以产生对应于预定方向（x，y）上的轴的倾斜位移的倾斜位移信号（S x x，S y y）。从倾斜位移信号（S？x，S？y）导出倾斜控制信号（A？x，A？y）这些变换产生用于驱动磁性轴承装置中的电磁致动器的致动器控制信号。根据本发明，倾斜矢量围绕装置轴线（z）以第一预定旋转方向旋转的倾斜位移与倾斜方向矢量围绕装置轴线（z）绕其旋转的倾斜位移分开控制，第二与第一预定旋转方向相反的旋转感。以这种方式，可以在不影响叶片振动或轴弯曲模式的情况下实现章动和进动的控制。

摘要： A distance sensor and a magnetic bearing device with such a sensor are disclosed. The sensor includes at least two essentially coplanar sensor coils (21, 22) which are operated in a manner in which magnetic fields generated by the sensor coils cancel at least partially in the regions inside the innermost and outside the outermost sensor coils. In a magnetic bearing device, such a sensor may be employed as an axial displacement sensor for the thrust disk (12). Preferably the sensor coils (21, 22) are essentially enclosed by an axial bearing unit (7) and the thrust disk (12). Thereby, the magnetic flux path of the control coil (72) is separated from the active sensor region, cross talk from the control coil (72) to the sensor coils (21, 22) is minimized, and effects of external disturbances are minimized. In addition, a novel rotation sensor is disclosed.

摘要： A magnetic bearing device and a method of operation for such a device are provided. The device comprises a group (410) of electromagnetic actuators (411, 412, 413, 414). Each actuator is electrically connected to an amplifier unit (701). The actuators of a first subgroup are connected to a first common node (608), while the actuators of a second subgroup are connected to a second common node (609). The common nodes (608, 609) are connected either directly or through means like an additional actuator. Preferably the common nodes (608, 609) have no additional electrical connection to the amplifier unit. According to a special embodiment of the invention, each subgroup of actuators consists of only one single actuator and the common node has an electrical connection to the amplifier. Thus the device comprises two actuators in a series configuration connected to an H bridge. The common node may be connected to either of two different voltages. The invention enables simplified wiring without increased load requirements for the wires.
