Apparatus for registering a number of revolutions

Abstract

Ein Drehgeber erzeugt ein stetiges Winkelsignal Us, das sich mit dem Winkel einer Drehwelle periodisch bei jedem Durchgang durch äquidistante Winkelstellungen ϕo, ϕ'o (mittlerer Abstand φ) wiederholt. Alle Durchgänge werden innerhalb des Meßzeitraumes T gezählt (Anzahl n). Das Winkelsignal ist jeweils ein Maß für die momentane Winkelstellung (ϕ'1, ϕ'2) bezogen auf eine der äquidistanten Winkelstellungen. Erfindungsgemäß wird das stetige Winkelsignal Us am Anfang (t1) und am Ende (t2) des Meßzeitraumes (Winkel ϕ1(ti), ϕ2 (t2)) aus dem Drehgeber herausgeführt und daraus die Differenz gebildet. Wird der Meßzeitraum T frei vorgegeben und gemessen, so ist ein der Drehzahl auch noch beim Stillstand proportionaler Meßwert.
