  • Slip ring system with improved cooling
    Patent number: 11916467
    Abstract: 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.
    Type: Grant

  • Slip ring unit with cooling fan insulating segment
    Patent number: 11043877
    Abstract: A slip ring unit for an electrical machine is provided for accommodating a carbon brush system. The slip ring unit includes at least one insulating segment having shaped sections for cooling parts of the electrical machine. The insulating segment having the shaped sections is shaped from the insulating segment as a fanwheel, wherein the insulating segment having the shaped sections forms a fan to distribute a cooling air flow to the parts of the electrical machine to be cooled. The slip ring unit has boreholes on the sides of supports of the slip rings for passage of cooling air.
