Abstract

Für eine Geschwindigkeitsregelung und/oder eine Kommutierung eines Motors ist es bekannt, dem Motor mehrere Sensoren zuzuordnen, die mehrere, die Rotorstellung anzeigende, gleichartige, gegeneinander phasenverschobene Sensorsignale erzeugen. Daraus werden in eine Hysterese aufweisenden Komparatoren Steuersignale für die Kommutierung oder die Geschwindigkeitsregelung gewonnen. Den Signalen an den Ausgängen der Sensoren sind in der Praxis Störungen überlagert, die z.B. von den Motorspulen stammen und die Auswertung beeinflussen. Aufgabe ist es, eine Schaltung der gennanten Art so aufzubauen, daß sie auch bei Motorstillstand in der Lage ist, Störungen zu unterdrücken, und diese Fähigkeit zeitlich unbegrenzt aufrechterhält. Gemäß der Erfindung sind Schaltungsmittel vorgesehen, die bewirken, daß jeweils an dem Komparator (A) für ein Sensorsignal (a) der Betrag der Hysterese von der Amplitude eines oder mehrerer der anderen Sensorsignale (b, c) abhängig ist. Vorzugsweise werden die Sensorsignale einer ODER-Stufe (Da, Db, Dc) zugeführt, deren Ausgangsspannung die Hysterese an den Komparatoren (A, B, C) steuert. Insbesondere zur Geschwindigkeitsregelung oder Kommutierung eines Capstanmotors in einem Videorecorder.
