    • A machine has a rotor and includes a converter-controlled drive and a working machine, wherein the drive and the working machine are connected such that a torque is transmitted. A frequency converter is electrically connected to the drive. The frequency converter is embodied such that in a Campbell diagram intersection points are based on the natural torsional frequency of the rotor and V-shaped symmetrical straight lines of the inter-harmonic exciter frequency for output frequencies. The output frequencies are grouped into a plurality of concentration ranges based upon a rotational speed of the machine, wherein each concentration range comprises output frequencies which are close to one another and which respectively have a common output point on the abscissa of the Campbell diagram. Each concentration range defines a blocking range, wherein the machine has an operating rotational speed range which lies outside the blocking ranges.
    • 机器具有转子并且包括转换器控制的驱动器和工作机械,其中驱动器和作业机器连接成传递转矩。 变频器电连接到驱动器。 变频器被实现为使得在坎贝尔图中,交点是基于转子的自然扭转频率和用于输出频率的谐频激励器频率的V形对称直线。 基于机器的转速将输出频率分组为多个浓度范围,其中每个浓度范围包括彼此接近并且在Campbell图的横坐标上分别具有公共输出点的输出频率。 每个浓度范围限定阻塞范围,其中机器具有位于阻挡范围之外的操作转速范围。
