Oscillation exciter

摘要

The generator has an exciter transmission comprising two imbalance masses (811, 831) that are attached on a set of shafts (8, 9). A pivot motor (3) adjusts a rotational position of the imbalance masses relative to one another. A lubrication pump is provided with the pivot motor, where the pump is operated by the shaft of the exciter transmission. The pivot motor is operated with transmission oil of the exciter transmission. The pivot motor has an inflow line. A filter is arranged in the inflow line.
