Description

Einrichtung zur Konstanthaltung der Drehzahl eines Elektromotors, dessen Ständer drehbar gelagert und mit einer besonderen Antriebsvorrichtung gekuppelt ist Bei einer großen Reihe von Antrieben besteht die Bedingung, daß die Drehzahl praktisch konstant bleibt. Diese Bedingung muß eingehalten werden, gleichgültig von welcher Art die antreibende Kraftmaschine ist, d. h. ob es sich um eine Dampfkraftmaschine, Brennkraftmaschine, Wasserkraftmaschine oder elektrische Maschine handelt.Device for keeping the speed of an electric motor constant, its stand rotatably mounted and coupled with a special drive device For a large number of drives, the condition is that the speed remains practically constant. This condition must be met, no matter what type of driving engine is, d. H. whether it is a steam engine, Internal combustion engine, water power machine or electrical machine is.

Die Aufgabe läßt sich auf zwei Wegen lösen, nämlich entweder dadurch, daß man die der antreibenden Kraftmaschine zuzuführende Energiemenge beeinflußt oder daß man auf mechanischem Wege durch ein Zwischengetriebe eine Summen- oder Differenzbewegung auf die antreibende oder angetriebene Maschine überträgt. Andere mit stetiger Änderung des Übersetzungsverhältnisses arbeitende Zwischengetriebe, wie Reibradgetriebe oder Riementriebe mit Kegelscheiben, bewähren sich nur in Sonderfällen, während die Einfügung einer Summen- oder Differenzbewegung nur verhältnismäßig kleine Energiemengen benötigt.The problem can be solved in two ways, namely either by that one influences the amount of energy to be supplied to the driving engine or that by mechanical means through an intermediate gear a sum or Transferring differential movement to the driving or driven machine. Other intermediate gears working with constant change of the transmission ratio, such as friction gears or belt drives with conical pulleys, only prove themselves in special cases, while the insertion of a sum or difference movement is only relatively small Amounts of energy required.

Von dem Prinzip der zusätzlichen übertragung einer Summen- oder Differenzbewegung auf die antreibende bzw. angetriebene Maschine wird gemäß der Erfindung bei einem elektrischen Antriebe Gebrauch gemacht, und zwar wird ein Elektromotor verwendet, dessen Ständer in bekannter Weise drehbar gelagert -und mit einer besonderen Antriebsvorrichtung gekuppelt ist. Der Elektromotor wird mit einem Geschwindigkeitsregler ausgerüstet, der bei Abweichungen der Istgeschwindigkeit von der Sollgeschwindigkeit über einen elektrischen Regelapparat die Antriebsvorrichtung des drehbar gelagerten Ständers in der Weise steuert, daß die dem Ständer erteilte Zusatzbewegung der Drehzahländerung entgegengesetzt gleich ist.From the principle of the additional transmission of a sum or difference movement on the driving or driven machine is according to the invention at a electric drives are made use of, namely an electric motor is used, whose stand is rotatably mounted in a known manner - and with a special drive device is coupled. The electric motor is equipped with a speed regulator, in the event of deviations in the actual speed from the target speed via a electrical control apparatus the drive device of the rotatably mounted stand controls in such a way that the additional movement given to the stator of the speed change opposite is equal.

In der Abbildung ist ein Ausführungsbeispiel der Erfindung dargestellt.In the figure, an embodiment of the invention is shown.

Der Elektromotor 17 soll die Arbeitsinaschine i mit konstanter Drehzahl antreiben. Zur Durchführung der Erfindung ist das Gehäuse der Maschine nicht feststehend ausgebildet, sondern auf der Welle i8 drehbar gelagert und mit einem Zahnrad i9 verbunden, in das ein Ritze12o eingreift. Sinkt die Drehzahl der Arbeitsmaschine i ab, so wird durch einen Fliehkraftregler 12 ein Regelwiderstand 13 eingeschaltet und ein Motor 15 zum Anlaufen gebracht, und zwar in einer Richtung, daß die Bewegung des umlaufenden Gehäuses 21 gleichsinnig mit der Bewegung des Ankers 17 ist. Es wird also auf den Anker 17 auf elektrischem Wege eine Differenzbewegung übertragen, die der Drehzahländerung entgegengesetzt gleich ist.The electric motor 17 is intended to operate the machine i at a constant speed drive. In order to carry out the invention, the housing of the machine is not stationary formed, but rotatably mounted on the shaft i8 and with a gear wheel i9 connected, in which a crack12o engages. The speed of the driven machine drops i from, a control resistor 13 is switched on by a centrifugal governor 12 and a motor 15 started, in one direction that the movement of the rotating housing 21 is in the same direction as the movement of the armature 17. It a differential movement is thus transmitted electrically to armature 17, which is the opposite of the change in speed.
