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.
Claims14
A ventilation system of a slip ring system of an electrically excited dynamoelectric machine, the slip ring system defining an axis about which the slip ring system rotates comprising:
- a carrier segment that includes a brush holder comprising a brush pocket for receiving a brush, and a surface-enlarging structure, and
- means for cooling the brush in the brush holder or for cooling the brush holder with a cooling air flow guided in or on the slip ring system, which is closed or open, in a radial and in a circumferential direction past the brush holder,
- wherein the radial and the circumferential directions are orthogonal to the axis.
A dynamoelectric machine, comprising:
- a slip ring system which is closed or open and includes a carrier segment comprising a brush holder which includes a brush pocket for receiving a brush and has a surface-enlarging structure;
- and
- a ventilation system including means for cooling the brush in the brush holder or for cooling the brush holder with a cooling air flow guided in or on the slip ring system in a radial and in a circumferential direction in relation to an axis of the slip ring system, about which axis the slip ring system rotates, past the brush holder,
- wherein the radial and the circumferential directions are orthogonal to the axis.
A slip ring system of an electrically excited dynamoelectric machine, said slip ring system defining an axis about which the slip ring system rotates and comprising:
