Description

Motorgenerator mit einer Gleichstrommaschine und asynchronem Antriebsmotor mit getrennt aufgestellter und mit der Umdrehungsfrequenz des Motors erregter Kommutatorhintermaschine zur Drehzahl- und Phasenregelung. Bei Motorgeneratoren, deren Motor eine Asynchronmaschine ist, kann man die Drehzahl und die Phase der Asynchronmaschine in bekannter Weise mittels einer Kommutatorhintermaschine regeln, die in Kaskade mit der induzierten Wicklung der Asyn.chronmaschine geschaltet und mit -einer Belastungsmaschine gekuppelt ist. Will man die Asynchronmaschine durch den Synchronismus hin. durchr:egeln, so wird die Kommutatorhintermaschine zweckmäßig von einer Synchronmaschine erregt, die die Umdrehungsfrequenz der Asynchronmaschine besitzt und die zu diesem Zweck mit dieser entsprechend gekuppelt wird.Motor generator with a direct current machine and asynchronous drive motor with a separately installed commutator rear machine that is excited at the speed of rotation of the motor for speed and phase control. In the case of motor generators whose motor is an asynchronous machine is, the speed and the phase of the asynchronous machine can be known in a known manner regulate by means of a commutator back machine that cascades with the induced The winding of the asynchronous machine is switched and coupled to a load machine is. If one wants to get the asynchronous machine through synchronism. durchr: rule, so becomes the commutator back machine expediently from a synchronous machine excited, which has the rotational frequency of the asynchronous machine and to this Purpose is coupled with this accordingly.

Nach der Erfindung wird diese besondere Erregermaschine bei Vorhandensein von Gleichstrommaschinen im Umformersatz dadurch erspart, daß man die Erregung einer Gleichstrommaschine dies Umforinersatzes entnimmt, und zwar entweder einer vorhandenen Gleichstromhauptmaschine oder einer Gleichstrom:erregermaschine. Die Polzahl der betreffenden Gleichstrommaschine wird alsdann so gewählt, daß die Maschine die erforderliche Umdrehungsfrequenz der Asynchronmaschine liefern kann.According to the invention, this particular exciter machine is present of direct current machines in the transformer replacement is saved by the fact that one excites a DC machine removes this Umforin Ersatzes, either an existing one DC main machine or a DC exciter machine. The number of poles of the relevant DC machine is then chosen so that the machine provides the required Can supply rotational frequency of the asynchronous machine.

Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt. Abb. i zeigt die aus dem Netz a gespeiste Asynchronmaschine a, die mit dem Gleichstromgenerator g zusammengekuppelt ist. In Kaskade mit dem induzierten Teil der Asynchronmaschine liegt die Kommutatormaschine k, die mit ihrer Belastungsmaschine h mechanisch verbunden ist. Nach der Erfindung ist der Gleichstromgenerator g mit Schleifringen s versehen, die mit den Schleifringen r der Kommutatorhintermaschine k verbunden sind und diesen den Erregerstrom aus dem Gleichstromgenerator zuführen. Zwischen die beiden Schlenfri@-gruppen ist im vorliegenden Falle noch ein Transformator t geschaltet, der den Erregerstrom auf die geeignete Spannung umformt.Two embodiments of the invention are shown in the drawing. Fig. I shows the asynchronous machine a fed from the network a, the one with the direct current generator g is coupled together. In cascade with the induced part of the asynchronous machine lies the commutator machine k, which is mechanically connected to its load machine h is. According to the invention, the direct current generator g is provided with slip rings s, which are connected to the slip rings r of the commutator back machine k and these supply the excitation current from the direct current generator. Between the two Schlenfri @ groups In the present case, a transformer t is also connected, which supplies the excitation current transformed to the appropriate voltage.

Bei der Anordnung nach Abb. 2 besteht der Umformersatz aus einer Asynchronmaschine a, einer Synchronmaschine c und. einer Erregergleichstrommaschine e. In diesem Falle wird die Erregung für die Kommutatorhinterm,aschine der Erregermaschine @entnommen.In the arrangement according to Fig. 2, the converter set consists of an asynchronous machine a, a synchronous machine c and. an exciter DC machine e. In this case the excitation for the commutator rear machine is taken from the excitation machine.

Bei Anwendung der Erfindung brauchen die Gleichstrommaschinen; denen der Erregerstrom für die Asynchronmaschineentnommen wird, nur unwesentlich größer bemessen zu werden als bisher, während auf der anderen Seite die Beschaffung, Erhaltung und Wartung :einer besonderen Erregermaschine erspart wird.When applying the invention, the DC machines need; those the excitation current for the asynchronous machine is taken only slightly larger to be measured than before, while on the other hand the procurement, conservation and maintenance: a special exciter is saved.
