Abstract

Die Erfindung betrifft ein Verfahren und eine Schaltungsanordnung zur Bestimmung der Menge des von einem elektrisch angetriebenen Schneidwerkzeug geschnittenen Schneidguts. Erfindungsgemäß werden die Schwankungen des von einem Antriebsmotor aufgenommenen Stroms erfaßt, gefiltert und ausgewertet. Durch Vergleich mit einem Referenzwert kann die Verschmutzung des Schneidwerkzeugs mit Schneidgutresten bestimmt werden. Die Erfindung ist insbesondere bei Rasierapparaten anwendbar.
