Abstract
The invention relates to a brush module (10) for a rotating electric machine, in particular for a current-excited synchronous machine, the brush module (10) having at least two brushes (12) for establishing electrical contact with slip rings (11) of the machine, the brush module (10) having a housing device (13) and brush holders (14) for accommodating and supporting the brushes (12), wherein the housing device (13) has a collecting device (21) for collecting brush dust of the brushes (12). Alternatively, the housing device (13) is configured in such a manner that the brush holders (14) are spaced apart from each other, the housing device (13) at least partially forming an air gap between the brush holders (14) on a housing portion of the housing device (13) that faces slip rings (11).
Claims14
A brush module (10, 30, 34) for a rotating electric machine, the brush module having at least two brushes (12, 35) for establishing electrical contact with slip rings (11, 36) of the machine, the brush module having a housing device (13, 31, 37) and brush holders (14, 41) for accommodating and supporting the brushes, characterized in that the housing device has a collecting device (21, 33, 46) for collecting brush dust of the brushes;
- wherein the collecting device has pockets for collecting brush dust, the pockets being disposed downstream of the brush in a direction of rotation of a slip ring, the pockets being formed by ribs extending in the direction of the rotation, and each brush is assigned its own collecting device.
A brush module (47) for a rotating electric machine the brush module having at least two brushes (48) for establishing electrical contact with slip rings of the machine, the brush module having a housing device (49) and brush holders (52, 53) for accommodating and supporting the brushes, characterized in that the housing device is configured in such a manner that the brush holders are spaced apart from each other, the housing device at least partially forming an air gap (55) between the brush holders on a housing portion (54) of the housing device that faces toward slip rings:
- wherein the housing device has a single housing body and forms the brush holders, the air gap is formed in the housing body, and a width of the air gap is formed as a function of a presumed operating voltage at the brushes.
