  1. P atentansprüche
    / 1. Motordrehzahl-Eegel sy stem, gekennzeichnet durch einen von einer —^ phasenge regelte η Spannungsquelle mit Tollwellengleichrichtung antreibbaren Gleichstrommotor (13)> eine Tollise lie n-phasenre gel schaltung (a) , umfassend einen Thyristor (6, 7) zur Regelung der Erregung des Gleichstrommotors (13)» eine Schaltung (F) zur Erzeugung von Säge zahnwellen durch Laden und Entladen eines ersten Kondensators (39) mit einer im Synchronismus mit einer Netzfrequenz als Geschwindigkeitsbezugsspannung einzusetzenden Gleichstromversorgung, eine Induktionsspannungsansprechschaltung (ß) zum Erfassen einer durch die Umdrehungen des Gleichstrommotors (13) bedingten induzierten Spannung und zum Speichern dieser induzierten Spannung in einem zweiten Kondensator (23), eine Begrenzer schaltung (C) zum Begrenzen der Ladespannung des zweiten Kondensators (23), wobei sich die Grenzspannung der Begrenzer schaltung (c) mit der als Ge schwindigke it sbe zugs spannung einzusetzenden Gleichstromversorgung ändert, eine Vergleichsschaltung (E.) zum Vergleichen der aus der Schaltung (f) zur Erzeugung von Säge zahnwelle η herrührenden Sägezahnwelle mit dem aus der Induktionsspannungsanspreohsohaltung (b) herrührenden E rfassungs signal und eine auf das Ausgangs signal der Vergleichsschaltung (E) im Sinne der Erzeugung eines Impulses zum Ansteuern des Thyristors (6, 7) ansprechende Impulsgeneratorschal tung (d).
  2. 2. Motordrehzahl -Kegelsystem nach Anspruch 1, dadurch gekennzeichnet, daß die Schaltung (ϊ1) zur Erzeugung von Säge zahnwellen einen Komparator (48) einbegreift, dem eine in beiden Halbwellen gleichgerichtete Netzspannung und eine geglättete, in beiden Halbwellen gleichgerichtete Netzspannung über eine Brücke η sch al tung zuleitbar sind, wobei der erste Kondensator (39) zum Geschwindigkeit sbe zug von der Gleichstromversorgung über einen ersten Widerstand (37) aufladbar und über einen zweiten Widerstand (38) entladbar ist und wobei das Laden und Entladen des ersten Kondensators (39) zum Erzeugen der Sägezahnwelle durch einen EIN-ATJS-Ausgang des Komparators (48) steuerbar ist.
    3- Mo tordreh zahl-Re gel system nach Anspruch 1, dadurch gekennzeichnet,
    030067/0691
