Mein Az.: DDW-2 w Den Demonstrationsmeßgeräten für Drehzeiger und Wellen liegt die Aufgabe zugrunde, ein Meßsignal willkürlich und kontinuierlich einstellbar in jeder Phase elektrisch so abzutasten, daß die Augenblicksspannung in der jeweiligen Phase mit einem Gleichspannungsmeßinstrument gemessen werden kann. Das Abtasten soll das Meßsignal in ein zeitlich linear gedehntes Ausgangssignal beliebig kleiner Prequenz, einschließlich der Frequenz f = O, überführen.My reference: DDW-2 w The demonstration measuring devices for rotary pointers and shafts are based on the task of randomly and continuously adjustable electrically sampling a measuring signal in each phase so that the instantaneous voltage in the respective phase can be measured with a DC voltage measuring instrument. The scanning is intended to convert the measurement signal into an output signal that is linearly stretched over time, of any frequency, including the frequency f = 0.
Sie wird mit dem Demonstrationsmeßgerät für Drehzeiger und Wellen (Ihr Az.: P 25 00 389.8) nur für bestimmte Frequenzen von Meßwechselspannungen, die durch die Frequenz für den Synchronmotor definiert sind, gelöst. It is used with the demonstration measuring device for rotary pointers and shafts (Your Ref .: P 25 00 389.8) only for certain frequencies of measuring alternating voltages, which are defined by the frequency for the synchronous motor, solved.
it der vorliegenden Neuanmeldung DDW-2 w wird die Aufgabe auf andere Wechselspannungen erweitert und allgemein für beliebig und kontinuierlich wählbare Frequenzen gelöst, Der Rahmen des Gerätes DDW-2 v kann auf einen Tageslichtprojektor aufgesetzt werden. Der Stator eines Asynchronmotors 1 und der-Stator eines Wechselspannungsgenerators 2 sind miteinander und mit dem Rahmen fest verbunden. Ihre Rotoren sitzen auf einer gemeinsamen Achse 3, auf die unter einem Winkel von 450 der Spiegel 5 einer Lichtschranke aufgesetzt ist. Über den Gehäusen der Statoren sitzt, drehbar um deren Achse 3 gelagert, ein Zahnkranz 4. ith the present new application DDW-2 w, the task is transferred to others Alternating voltages expanded and generally for arbitrarily and continuously selectable Frequencies solved, the frame of the device DDW-2 v can be on an overhead projector be put on. The stator of an asynchronous motor 1 and the stator of an alternating voltage generator 2 are firmly connected to each other and to the frame. Your rotors sit on one common axis 3 on which at an angle of 450 the mirror 5 of a light barrier is put on. The stators sit over the housings, rotatably mounted about their axis 3, a ring gear 4.
Vom Zahnkranz 4 führt ein Synchrontreibriemen an Den Zahnkranz einer Plexiglasscheibe 7 über dem Tageslichtprojektor. Die Scheibe 7 kann um die zur Achse 3 parallele Achse 6 gedreht werden.From the ring gear 4, a synchronous drive belt leads to the ring gear Plexiglass 7 over the overhead projector. The disc 7 can to the axis 3 parallel axis 6 can be rotated.
Ein gedachter Pfeil auf dem Zahnkranz 4 und ein dazu parallel gezeichneter Pfeil auf der Scheibe 7 bleiben immer parallel, auch wenn man den Zahnkranz 4 und damit die Scheibe 7 dreht, Der Winkel eines Pfeiles auf der Scheibe 7 gegen eine Kante des Rahmens ist immer gleich dem Winkel eines Pfeiles auf dem Zahnkranz 4 gegen dieselbe Kante des Rahmens.An imaginary arrow on the ring gear 4 and one drawn parallel to it Arrow on the disk 7 always remain parallel, even if the ring gear 4 and so that the disc 7 rotates, the angle of an arrow on the disc 7 against a The edge of the frame is always the same as the angle of an arrow on the ring gear 4 against the same edge of the frame.
In Verlängerung der Achse 3 befindet; sich fest mit dem Rahmen des Gerätes verbunden, eine Lichtquelle8und eine Fotodiode 90 Auf dem Zahnkranz 4 befindet sich, fest mit 4 verbunden, ein senkrechter Spiegel 10. Bei jeder Umdrehung des Motors 1 wird in der Licht= schranke über den Weg 8 - 5 - 10 - 5 - 9 ein Impuls U2 ausgelöst.Located in extension of the axis 3; firmly attached to the frame of the Device connected, a light source 8 and a photodiode 90 located on the ring gear 4 itself, firmly connected to 4, a vertical mirror 10. With each revolution of the Motor 1 receives an impulse in the light barrier via path 8 - 5 - 10 - 5 - 9 U2 triggered.
Dieser schließt den, symbolisch als Relais eingezeichneten, elek= tronischen Schalter während der Impulsdauer. Dabei lädt sich der' Beschreibung Mein Az.: DDW-2 w Kondensator ii, wenn der Zahnkranz 4 ruht, immer in der selben Phasenlage der Teilspannung U3 des Meßkreises 12 auf, der an die Generatorspannung U;1 angeschlossen ist.This closes the elek =, which is symbolically drawn as a relay electronic switch during the pulse duration. The ' description My reference: DDW-2 w capacitor ii, when the ring gear 4 is at rest, always in the same one Phase position of the partial voltage U3 of the measuring circuit 12, which is connected to the generator voltage U; 1 is connected.
Dreht man den Zahnkranz 4 um 1/4 Umdrehung, so verschiebt sich das Auiösen der Impulsschranke um 1/4 Periodei. Gleichzeitig wird die Scheibe 7 mit evt. darauf eingezeichneten Drehzeigern um 1/4 Periode oder 900 gedreht. Läßt man den Zahnkranz 4 langsam rotieren, so rotiert die Scheibe 7 synchron mit, das Voltmeter V zeigt eine langsame Wechselspannung. Sein Ausschlag ist immer gleich dem sinus-Wert eines auf der Scheibe 7 einzuzeichnenden, mitrotierenden Drehzeigers. If the ring gear 4 is rotated by 1/4 turn, the release of the impulse barrier is shifted by 1/4 period. At the same time, the disk 7 is rotated by 1/4 period or 900 with the rotary pointers possibly drawn on it. If the ring gear 4 is allowed to rotate slowly, the disk 7 rotates synchronously with it, and the voltmeter V shows a slow alternating voltage. Its deflection is always equal to the sine value of a rotating pointer to be drawn on disk 7.
