Abstract

Es werden eine Vorrichtung und ein Verfahren zur Überwachung der Abnützung einer Bürste (12) des Schleifbahn- oder Kommutatorsystems (10) einer elektrischen Maschine vorgeschlagen, wobei eine kontaktlose Sensoreinrichtung ein dem Bürstenverschleiß entsprechendes Signal an eine Auswerteinheit (34) liefert. Erfindungsgemäß ist die Sensoreinrichtung als Impedanzsensor (24) ausgebildet und ortsfest, vorzugsweise am Bürstenhalter (18) der Maschine angeordnet, benachbart zu der im Bürstenhalter (18) verschiebbaren Bürste (12). Zur Ermittlung des Bürstenverschleißes ist die Bürste (12) nach Art eines Zweikomponenten-Bauteils gestaltet, wobei wenigstens ein Abschnitt (36) der Bürste (12) eine elektrische Leitfähigkeit (γ2) aufweist, die sich von der Leitfähigkeit (γ1) der Grundsubstanz (35) der Bürste (12) deutlich unterscheidet. Der durch den Impedanzsensor (24) erfassbare Abschnitt (36) mit der von der Leitfähigkeit der Grundsubstanz der Bürste (12) abweichenden elektrischen Leitfähigkeit (γ2) ist zweckmäßigerweise an dem vom Schleifbahn- oder Kommutatorsystem (10) abgewandten Ende der Bürste (12) angeordnet und gelangt erst am Ende der Betriebsbereitschaft der Bürste als Verschleißanzeige in den Messbereich des Impedanzsensors
