Abstract
A vacuum extraction system is provided for extracting contaminants from rotating electrical devices. In an exemplary embodiment, the vacuum extraction system extracts conductive dust from the current collection system of a synchronous generator with a static excitation system. As the brushes ( ) of the static excitation system wear against the collector rings ( ), they produce conductive dust, which if permitted to accumulate, may cause electrical shorts and arcing and severe damage to the rotating electrical device. Methods and systems consistent with the vacuum extraction system of the present invention extract conductive dust from a rotating electrical device through vacuum passages ( ) in the rotating electrical device into a removable dust capture media ( ) to prevent dust accumulation and possible electrical damage. The vacuum passages of the vacuum extraction system may comprise, for example, nozzles ( ), through-holes ( ) in a brush ( ), grooves ( ) in a brush ( ), through-holes ( ) in a brush holder ( ), or grooves ( ) in a brush holder ( ).
