摘要： A slip ring system of an electrically excited dynamoelectric machine can be designed to be closed or open and includes a carrier segment configured to include a brush holder which includes a brush pocket for receiving a brush. The brush holder includes means for cooling the brush in the brush holder and/or for cooling the brush holder and has a surface-enlarging structure so as to enable a cooling air flow to be guided within the slip ring system and thereby cool the brush holder and/or brush pocket.
