摘要： In a method for monitoring a magnetic bearing apparatus a first pair of at least essentially diametrically opposed sensors and a second pair of at least essentially diametrically opposed sensors are arranged in offset relation about an angle. A distance of each of the sensors from a rotating body arranged inside the first and second pairs of sensors is determined by temporal averaging of a plurality of distance measurements. The distances of the sensors from the rotating body are compared and a warning signal is outputted when a difference in the distances exceeds a limit value.

摘要： A device for measuring a clearance between tips of blades of a ring of blades and an interior wall of a casing surrounding the ring of blades in a turbomachine includes a probe which is mounted radially on the casing. The probe has an end made of a material that can be abraded by the tips of blades as they rotate. The device also includes a printed circuit arranged in a mid-plane of the probe. The probe contains an axis of rotation of the ring of blades. Further, the printed circuit includes a number of adjacent U-shaped electrical circuits that have bases arranged in a probe end likely to be abraded by the tips of blades. The bases lie at different depths from a reference level defining the interior wall of casing. The printed circuit also includes a recognizer for determining which U-shaped electrical circuits have been broken by abrasion and which U-shaped electrical circuits are intact.

摘要： In an active magnetic bearing system employing radial or thrust bearings, rotor shaft position is determined without requiring air gap position sensors, resulting in a high reliability system. The flux paths for each respective electromagnetic force actuator of the active magnetic bearing are isolated in order to minimize the magnetic coupling therebetween. The active magnetic bearing system is controlled for mutually exclusive excitation of each of the two actuators (e.g., stator pole pairs) per control axis. A sequence of test voltage pulses is applied to the unexcited one of each actuator pole-pair. At the peak of an applied test voltage pulse, after a predetermined time interval, the pole flux linkage is estimated using either an analog or software integrator. The integrator is reset at zero current, and hence zero flux, thereby avoiding accumulation of errors. The effective air gap length is determined from the inherent magnetization characteristic of the magnetic bearing using the measured current and the estimated flux linkage. Effectively, each magnetic pole is used alternately for force actuation and for inductive feedback sensing, eliminating the need for separate position sensors.
摘要翻译：在采用径向或推力轴承的主动磁轴承系统中，确定转子轴位置，而不需要气隙位置传感器，从而产生高可靠性系统。主动磁轴承的每个相应电磁力致动器的磁通路径是隔离的，以便使它们之间的磁耦合最小化。控制主动磁轴承系统，用于每个控制轴的两个致动器（例如，定子极对）中的每一个相互排斥的激励。将一系列测试电压脉冲施加到每个致动器极对中的未激励的一个。在施加的测试电压脉冲的峰值处，在预定时间间隔之后，使用模拟或软件积分器来估计极点磁链。积分器在零电流下复位，因此零通量，从而避免误差累积。有效气隙长度根据使用测量电流和估计磁通量的磁轴承的固有磁化特性确定。有效地，每个磁极交替地用于力致动和用于感应反馈感测，消除了对单独的位置传感器的需要。

摘要： The diametral clearance of an aperture of a bearing is measured by an apparatus which includes a mounting for placing both the bearing and an associate pivot in axial relation with each other along an axis of alignment and positioning devices for positioning the pivot in relation to the bearing. The positioning devices include axial direction positioning devices for adjusting the pivot in each of two mutually perpendicular axial directions transverse to the axis of alignment to locate an approximate center of bearing clearance and for adjusting the pivot from the approximate center of bearing clearance in each of the mutually perpendicular axial directions until the pivot displaces the bearing in the corresponding direction. Also included are gaging devices for measuring any movement of both the bearing and pivot in each of the mutually perpendicular axial directions, and an indicator for indicating any axial movement of the bearing and the pivot while the positioning devices adjust the pivot in each of the two mutually perpendicular axial directions.

摘要： In a method for monitoring a magnetic bearing device for an electric rotating machine, a first pair of at least essentially diametrically opposed sensors and a second pair of at least essentially diametrically opposed sensors are arranged in offset relation about an angle. A distance is determined between each of the sensors and a body of rotation arranged inside the first and second pairs of sensors. A first average distance is determined from distance values of the first pair of sensors and a second average distance is determined from distance values of the second pair of sensors. A first change in the first average distance is captured and a second change in the second average distance is captured. The first and second changes are compared and a warning signal is outputted when a difference between the first and second changes exceeds a limit value.
