In den Zinken 1 ο,11 bzw. 12,13 der Halterungsvorrichtungen 8 bzw. 9 sind Sender 14 und Empfänger 15 je einer fotoelektrischer Einrichtung (Lichtschranke) eingebaut. Beim Durchlauf der zahnförmigen Leiterverbindungen 3 durch die Lichtsohranken 14/15 werden diese in periodischer Folge von den einzelnen Leiterverbindungen 3 unterbrochen, so daß am Ausgang jedes Empfängers 15 ein impulsförmiges elektrisches Signal gebildet ist, bei welchem jeder Impuls dem Durchlauf einer·zahnförmigen Leiterverbindung 3 entspricht.In the prongs 1 o, 11 or 12, 13 of the mounting devices 8 or 9, transmitter 14 and receiver 15 are each built into a photoelectric device (light barrier).

utD einen beliebigen Winkel mit Ausnahme von 18o el. gegeneinander phasenverschoben sind. Aus dem Vorzeichen dieser Phasenverschiebung läßt sich dann die Drehrichtung des Rotors 1 bestimmen. Die Wahl des Abstandes zwischen den beiden Halterungsvorrichtungen 8 und 9 erfolgt dabei in der Weise i daß der Abstand kein ganzzahliges Vielfaches des halben Abstandes zweier Leiterverbindungen beträgt. Wird diese Forderung nämlich nicht erfüllt, so sind die beiden impulsförmigen Ausgangssignale der Empfänger 15 entweder um 18o el. oder um 0 el. phasenverschoben, wodurch die beabsichtigte Ermittlung der Rotordrehrichtung aufgrund der fehlenden Eindeutigkeit nicht möglich ist.utD any angle with the exception of 18o el. are out of phase with one another. The direction of rotation of the rotor 1 can then be determined from the sign of this phase shift. The choice of the distance between the two mounting devices 8 and 9 is effected in such a manner that the distance i is not an integer multiple of half the distance between two conductors is compounds. If this requirement is not met, the two pulse-shaped output signals of the receivers 15 are phase shifted either by 18o el. Or by 0 el.
Zu der voran-stehend beschriebenen Auswertung der impulsförmigen Ausgangssignale der Kmpfanger 15 sind diese elektrisch mit einer elektronischen Einrichtung 16 verbunden. Die Auswerteinrichtung 16 kann entweder unmittelbar auf der Montageplatte 7 befestigt sein oder mechanisch getrennt von dem Scheibenläufer-motor angeordnet werden.For the evaluation of the pulse-shaped Output signals of the Kmpfanger 15 are these electrically with an electronic device 16 connected. The evaluation device 16 can either be placed directly on the mounting plate 7 be attached or mechanically separated from the pancake motor to be ordered.
