Ankerwicklungen.Armature windings.
Bei Einankermaschinen mit getrennten, je an besondere Stromwender angeschlossenen Wicklungen ist es praktisch schwierig, beide Stromwender zum funkenfreien Lauf zu bringen. Liegen die Ankerwicklungen übereinander in denselben Nuten, so sind die Reaktanzspannungen beider Wicklungen verschieden, liegen sie nebeneinander, so sind die Wicklungen um einen räumlichen Winkel gegeneinander verstellt. Ein räumlich veränderliches Wendefeld ist daher nicht imstande, in beiden Wicklungen gleichzeitig die für gute Kommutierung erforderliche Wende-E. M. K. zu induzieren.With single-anchor machines with separate commutators, each connected to a special commutator Windings, it is practically difficult to get both commutators to run spark-free. If the armature windings lie one above the other in the same slots, the reactance voltages are Both windings are different, if they are next to each other, the windings are at a spatial angle to each other adjusted. A spatially variable turning field is therefore not able to move into both windings at the same time the reversing E required for good commutation. M. K. to induce.
Die Erfindung bezweckt, die Schwierigkeiten der Kommutierung zu beheben, unabhängig
davon, ob es sich um übereinander oder nebeneinander angeordnete Wicklungen handelt.
Gemäß der Erfindung wird der Verschiedenheit der Reaktanzspannungen bzw. der Verschiedenheit
des Einflusses verschiedener Wendefelder dadurch Rechnung getragen, daß der
Strom in derjenigen Ankerwicklung, in welcher eine größere Reaktanzspannung auftreten
oder eine geringere Wende-Ε. M. K. induziert würde, geringer gehalten wird als in der anderen
Wicklung.The aim of the invention is to eliminate the difficulties of commutation, regardless of whether the windings are one above the other or one next to the other.
According to the invention, the difference in the reactance voltages or the difference in the influence of different turning fields is taken into account in that the current in that armature winding in which a greater reactance voltage occurs or a lower turning-Ε. MK induced is kept lower than in the other winding.
Fig. ι stellt den Fall eines Motors dar. Es bezeichnet w die Wendewicklung, h die FeIdwicklung, r einen gegebenenfalls regelbaren Widerstand, A0 die obere Ankerwicklung, A11 die untere Ankerwicklung in der Nut. Zur Verminderung des Stromes in der unteren Ankerwicklung, in der eine größere Reaktanzspannung auftreten würde als in der oberen, wird die Feldwicklung parallel zur unteren Ankerwicklung A11 gelegt. Außerdem kann, falls erforderlich, ein unter Umständen regelbarer Widerstand r parallel zu dieser Wicklung gelegt werden.Fig. 1 shows the case of a motor. It denotes w the reversing winding, h the field winding, r an optionally controllable resistor, A 0 the upper armature winding, A 11 the lower armature winding in the slot. To reduce the current in the lower armature winding, in which a greater reactance voltage would occur than in the upper one, the field winding is placed parallel to the lower armature winding A 11 . In addition, if necessary, a resistor r, which can be regulated under certain circumstances, can be placed parallel to this winding.
Fig. 2 zeigt den entsprechenden Fall eines Generators. Hier ist der Strom in der Wicklung A ο größer als in der Wicklung A u, weil erstere noch den Widerstand r und die Nebenschlußwicklung h zu speisen hat.Fig. 2 shows the corresponding case of a generator. Here the current in the winding A o is greater than in the winding A u , because the former still has to feed the resistor r and the shunt winding h.
Sind beide Wicklungen — wie dies in Fig. 3 dargestellt ist — parallel geschaltet, so kann man in den Stromkreis der einen Ankerwicklung, z.' B. A11, einen Widerstand, der ganz oder zum Teil auch aus der etwa vorhandenen Reihenfeldwicklung s bestehen kann, schalten.If both windings - as shown in Fig. 3 - connected in parallel, you can in the circuit of one armature winding, z. B. A 11 , a resistor that may consist entirely or in part of any existing series field winding s, switch.
