    • The invention relates to a method for reducing wobbling of a rotating rotor body (1) which is mounted in a freely suspended manner and which comprises reflecting surfaces (13) on the outer periphery thereof. According to the inventive method, a measuring beam (5) having a predetermined point of incidence is reflected by the rotating reflecting surfaces (13) of the rotating rotor (1) and are directed onto a position detector (17) after having been reflected. The signals of said detector are fed to a computer (22). The computer determines the difference between the largest and smallest value of the signals output by the position detector (17) during a complete rotation of the rotor body (1), as well as the angular positions of the rotor body (1) corresponding to said values, and calculates control signals therefrom for the correcting device (16). This causes a change in the distribution of mass on the rotor body (1) during the rotation or a subsequent rotation of the same. This change in the distribution of mass is effected in a manner which contactless and which does not have an affect on the reflecting surfaces (13) such that the subsequently determined difference between the smallest and largest value of the signals output by the position detector (17) is less than the difference determined during the previous rotation. The invention also relates to a device for carrying out such a method.
    • 在用于降低在自由浮动轴承摇摆运动,旋转具有在其外圆周上Refexionsflächen(13)(1)的转子体,测量光束(5)预定Einstrahllage的到旋转的转子体的通过反射面(13)的方法( 1)和反射(在反射17之后)指向的位置检测器,其信号被馈送到一个计算机(22)。 这确定的最大和最小值之差来自位置检测器(17)的输出信号的转子本体(1)的一个完整旋转期间和属于该转子本体(1)的两个角位置,并计算所述修正装置(16)的控制信号。 这导致或转子体的后续转数(1)在该非接触的质量分布的变化,不影响反射面(13),使得位置检测器的最小和最大值之间的再检测的差异(17)的输出信号小于 某些在前面的转速差。 还描述了一种用于执行这种方法。
