Description

Anordnung zur Regelung von ständergespeisten Drehstromnebenschlußmotoren, für deren Drehzahlregelung ein als einfacher Drehtransformator ausgebildeter Grundtransformator und ein Doppeldrehtransformator vorgesehen sind Das Hauptpatent betrifft eine Anordnung zur Regelung von ständergespeisten Drehstromnebenschlußmotoren, für deren Drehzahlregelung ein als einfacher Drehtransformator ausgebildeter Grundtransformator und ein Doppeldrehtransformator vorgesehen sind. Die Spannung des Doppeldrehtransformators ist in Zu- und Gegenschaltung zur Spannung des Grundtransformators regelbar. Der Grundtransformator liefert dabei außer der die Drehzahl beeinflussenden Spannung noch eine auf die Phasenkompensierung einwirkende Spannungskomponente.Arrangement for the regulation of stator-fed three-phase shunt motors, a basic transformer designed as a simple rotary transformer for their speed control and a double rotary transformer are provided. The main patent relates to an arrangement for the regulation of stator-fed three-phase shunt motors, for their speed regulation a basic transformer designed as a simple rotary transformer and a double rotary transformer are provided. The voltage of the double rotary transformer is connected in and out adjustable to the voltage of the basic transformer. The basic transformer delivers in addition to the voltage influencing the speed, there is also one on the phase compensation acting stress component.

Die Erfindung betrifft eine Verbesserung dieser Anordnung in baulicher Hinsicht. Erfindungsgemäß sind bei Anordnungen, bei denen für mehrere Drehstromnebenschlußmotoren ein gemeinsamer, gesondert aufgestellter Doppeldrehtransformator vorgesehen ist, den einzelnen Nebenschlußmotoren gesonderte Grundtransformatoren zugeordnet, die mit den Nebenschlußmotoren baulich je eine Einheit bilden, zweckmäßig derart, daß der Grundtransformator auf dem Ständerrücken des Motors angeordnet ist. An sich ist es bereits bekannt, an einem ständergespeisten Drehstromnebenschlußmotor den für die Drehzahlregelung dort benutzten einfachen Drehtransformator mit dem Nebenschlußmotor durch Aufbau auf dein Ständerrücken baulich zu vereinigen. Dabei handelt es sich aber nur um einzelne voneinander ganz unabhängige Drehstromnebenschlußmotoren. Ferner ist es bekannt, für die gemeinsame Drehzahlregelung mehrerer ständergespeister Drehstromnebenschlußmotoren einen gemeinsamen Doppeldrehtransformator vorzusehen. Demgegenüber bestellt das Neue der Erfindung darin, daß man bei Regelanordnungen, bei denen außer dem Doppeldrehtransformator noch ein Grundtransformator vorgesehen ist, diesen Grundtransformator nicht ebenfalls für alle Nebenschlußmotoren gemeinsam vorsieht, sondern jedem Nebenschlußmotor einen gesonderten Grundtransformator zuweist, während der Doppeldrehtransformator gemeinsam ist. Diese Anordnung bringt den Vorteil, daß man durch Einstellung an den einzelnen Grundtransformatoren die einzelnen Nebenschlußmotoren sowohl bezüglich der Drehzahl als auch bezüglich des Leistungsfaktors noch gesondert einstellen bzw. regeln kann.The invention relates to a structural improvement of this arrangement Respect. According to the invention are in arrangements in which for several three-phase shunt motors a common, separately installed double rotary transformer is provided, the individual shunt motors assigned separate basic transformers, the with the shunt motors structurally ever form a unit, expedient such that the basic transformer is arranged on the stator back of the motor. It is already known per se on a stator-fed three-phase shunt motor the simple rotary transformer used there for speed control with the To structurally unite the shunt motor by mounting it on the back of your stator. Included But it is only a matter of individual three-phase shunt motors that are completely independent of one another. It is also known for the common speed control of several stator-fed units Three-phase shunt motors provide a common double rotary transformer. In contrast, the novelty of the invention is that in the case of control arrangements, in which a basic transformer is provided in addition to the double rotary transformer is, this basic transformer is not also common to all shunt motors provides, but assigns a separate basic transformer to each shunt motor, while the twin rotary transformer is common. This arrangement has the advantage that you can adjust the individual shunted motors by setting the individual basic transformers both in terms of speed and in terms of the power factor can adjust or regulate.
