摘要： The invention inter alia relates to a method for monitoring the bearing current of an electrical machine (10). An electrode (100) arranged at a distance (d) to a shaft and the shaft—due to the gap (S) between the electrode and the shaft—produce a measurement capacitance (C) and an electric shift current (i) which flows through the measurement capacitance when there is a temporal change of the voltage (Ug) applied between the shaft and the housing is measured. A measurement signal (Ms) indicating a bearing current flow is generated when the shift current or a measurement variable produced by the shift current meets a predetermined trigger criterion. Preferably, the electrode has a circular inner contour so that the gap is annular. The annular inner contour results in an error compensation in the case of a balance error of the shaft because the factor dC/dt remains at least substantially constant. Due to the contactless measurement of the shift current, no contact brushes for contacting the shaft are required. The method can be used irrespective of whether the bearings are insulated from the machine housing or not.
摘要翻译：本发明尤其涉及用于监测电机（10）的轴承电流的方法。与电极和轴之间的间隙（S）距离（d）与轴和轴（距离）配置的电极（100）产生流过的测量电容（C）和电移动电流（i）当测量在轴和壳体之间施加的电压（Ug）的时间变化时，通过测量电容。当由换档电流产生的换档电流或测量变量满足预定的触发准则时，产生表示轴承电流的测量信号（Ms）。优选地，电极具有圆形内轮廓，使得间隙是环形的。由于因数dC / dt保持至少基本恒定，所以在轴的平衡误差的情况下，环形内轮廓导致误差补偿。由于移位电流的非接触式测量，不需要接触轴的接触刷。无论轴承是否与机器外壳绝缘，都可以使用该方法。

摘要： The grounding quality of an electric machine should be better monitored. Therefore, an electric machine is proposed, comprising a stator (1), a rotor (2), a shaft (3), to which the rotor (2) is fastened, and a grounding device (5) for grounding the shaft. The electric machine also has a measuring device (6) for measuring a ground current of the grounding device (5) and for providing a corresponding measured value. The electric machine also has a monitoring device (7) for monitoring the grounding function of the grounding device (5) on the basis of the measured value. In this way, the state of a grounding brush in regard to soiling and wear, for example, can be continuously monitored.

摘要： A force transducer, in particular a load cell, includes a spring body that deforms when loaded with a force or load to be measured. Two support parts, which are separated by a gap, are moved out of a position of rest. A capacitive displacement detector is used to detect the relative movement of the support parts, where the capacitor includes two electrode combs that are each held on one of the support parts and includes a multiplicity of electrode fingers. The electrode combs are configured designed and mounted on the two support parts such that the electrode fingers of the one electrode comb pass into the finger interspaces of the other electrode comb when the spring body is loaded so that the force transducer is resistant to overloading.

摘要： A method and device for assessing damage to a rolling bearing caused by bearing currents, in particular high-frequency bearing currents, in an electric machine which is electrically connected to an inverter, in particular to an inverter having a DC voltage link circuit, is described. The rolling bearing has a lubrication gap between an inner bearing ring and a rolling body and between an outer bearing ring and the rolling body. The method includes detecting the energy of an electric discharge event in the lubrication gaps, searching for a coincident event having a frequency above one GHz indicative of a damaging bearing current event, detecting a frequency of occurrence of discharge events, and evaluating the discharge events by correlating the frequency of occurrence and the energy of the discharge events.
