Delivery time: 8-12 business days (International)
Die vorliegende Arbeit entstand in den Jahren 1973 1977 im Rahmen des Forschungsschwerounktes "Elektrische Kleinantriebe" der Gesamthochschule Paderborn im Labor fur Elektrische Klein antriebe des Fachbereiches Nachrichtentechnik der Hochschul abteilung in Meschede als Fortsetzung fruherer Arbeiten, die im Bereich Kleiner Leistungen durchgefuhrt wurden. Fur die groBzugige finanzielle Forderung des Projektes durch den Minister fur Wissenschaft und Forschung des Landes Nordrhein Westfalen sind wir sehr dankbar. Wesentlichen Anteil an der Durchfuhrung der experimentellen Arbeiten hatten Herr Ing. (grad. ) Schroll und insbesondere die Herren Ing. (grad. ) Gretsch und Ing. (grad. ) Bruffer, denen wir fur ihre wertvolle Mitarbeit besonders danken. Wir wurden uns freuen, wenn das beschriebene Antriebselement bald Eingang in die Technik finden wurde.
