Description

Mehrphasenkommutatormaschine mit einer im Ständer untergebrachten und vom Anker durch Induktion gespeisten Wicklung Die Erfindung betrifft eine Anordnung, um bei Mehrphasenkommutatormaschinen, insbesondere bei Kommutatormaschinen, die als Hintermaschine für die Phasenkompensierung oder auch die Drehzahlregelung von Induktionsmaschinen dienen, eine Selbsterregung der Maschine herbeizuführen. Bekanntlich wird ein in den Sekundärstromkreis einer Asynchronmaschine eingeschalteter Phasenschieber durch den Belastungsstrom der Hauptmaschine erregt. Dabei ist aber eine Phasenkompensierung bei Leerlauf nicht möglich. Es ist für derartige Phasenschieber bereits bekannt, im Ständer in sich geschlossene Wicklungen zur Verbesserung der Kommutierung anzubringen, welche die bei der Kommutierung entstehenden Oberschwingungen wegdämpfen sollen und einen verhältnismäßig hohen Widerstand besitzen.Multi-phase commutator machine with one housed in the stand and winding fed by induction from the armature The invention relates to an arrangement to in multi-phase commutator machines, especially in commutator machines that as a rear machine for phase compensation or speed control of Induction machines are used to induce self-excitation in the machine. As is well known becomes a phase shifter connected to the secondary circuit of an asynchronous machine excited by the load current of the main engine. But there is a phase compensation not possible when idling. It is already known for such phase shifters to attach self-contained windings in the stator to improve commutation, which are intended to attenuate the harmonics that occur during commutation and have a relatively high resistance.

Die Mehrphasenkommutatormaschine nach der Erfindung besitzt im Ständer ebenfalls eine vom Anker durch Induktion gespeiste Wicklung, indessen müssen hier der Ohmsche und der induktive Widerstand der durch Induktion gespeisten Wicklung (Käfig-oder Phasenwicklung) derart gegeneinander abgeglichen sein, daß die Maschine ein möglichst hohes Drehmoment erzeugt, welches ausreicht, um die Erregerenergie des an den Kommutator angeschlossenen Stromkreises zu liefern. Wie die Versuche gezeigt haben, läßt sich die Selbsterregung in jedem Falle durch Bemessung des Ohmschen Widerstandes der Ständerwicklung erreichen.The multi-phase commutator machine according to the invention has in the stator also a winding fed by induction from the armature, but here the ohmic and inductive resistance of the winding powered by induction (Cage or phase winding) be balanced against each other in such a way that the machine generates as high a torque as possible, which is sufficient to generate the excitation energy of the circuit connected to the commutator. Like the trials have shown, the self-excitation can in any case by measuring the ohmic Reach resistance of the stator winding.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Für die Phasenkompensierung des Induktionsmotors I ist eine nur elektrisch mit dem Induktionsmotor verbundene Kommutatorhintermaschine 2 vorgesehen. 3 ist die Antriebsmaschine für die Kommutatorhintermaschine. Die Hintermaschine ist nun im Ständer mit einer Phasenwicklung 4 ausgerüstet. In dem Stromkreis der Phasenwicklung liegt zur Abgleichung des induktiven und des Ohmschen Widerstandes ein einstellbarer Ohmscher Widerstand 5. Diese Anordnung hat die Eigenschaft, daß die Kommutatorhintermaschine sich selbst erregt, so daß also eine Phasenkompensierung auch bei Leerlauf des Aggregats eintritt. Der in die Wicklung 4 eingeschaltete Regulierwiderstand 5 dient auch dazu, die Frequenz der durch die Selbsterregung erzeugten Spannung in der Hintermaschine zu beeinflussen.The drawing shows an embodiment of the invention. For the Phase compensation of the induction motor I is an only electrical one with the induction motor connected commutator back machine 2 is provided. 3 is the prime mover for the commutator back machine. The rear machine is now in the stator with a phase winding 4 equipped. In the circuit of the phase winding is to balance the inductive and the ohmic resistance an adjustable ohmic resistance 5. This arrangement has the property that the commutator rear machine excites itself, so that so a phase compensation occurs even when the unit is idling. The one in the Winding 4 switched on regulating resistor 5 is also used to adjust the frequency of the to influence the voltage generated by the self-excitation in the rear machine.

Statt die Hintermaschine im Ständer mit einer Phasenwicklung für die Selbsterregung auszurüsten, kann man auch eine Kurzschlußwicklung verwenden, wenn nur deren Ohmscher bzw. auch der induktive Widerstand dieser Kurzschlußwicklung einen entsprechenden Wert besitzt.Instead of the rear machine in the stator with a phase winding for the To equip self-excitation, one can also use a short-circuit winding, if only their ohmic or also the inductive resistance of this short-circuit winding has a corresponding value.
