Zusammenfassung:	The invention relates to a measuring device for measuring the wear of carbon brushes, comprising: a slip ring (3); a carbon brush (4), which is arranged for sliding in a sliding direction (5) and which is preloaded into sliding contact with the slip ring (3); an indicator material (7), which extends in the sliding direction (5) in, on or next to the carbon brush (4) and is connected to the carbonbrush (4) in such a way that the indicator material moves together with the carbon brush (4) at least with respect to the sliding direction (5), wherein the indicator material (7) is preloaded into sliding contact with the slip ring (3); an insulator (8), which is arranged between the carbon brush (4) and the indicator material (7) and electrically insulates the carbon brush (4) from the indicatormaterial (7); and a resistance-measuring apparatus (9) for measuring the resistance between two measurement points (10, 11; 10, 15), between which at least a section of the indicator material (7) anda section of the slip ring
