Description
Gleichstromhilfswicklung für den Läufer eines kompensierten Asynchronmotors mit stark verkürztem Wicklungsschritt Im Hauptpatent 452 o74 ist eine als Hilfswicklung bei kompensierten Asynchronmotoren dienende Gleichstromwicklung mit stark verkürztem Wicklungsschritt angegeben, bei welcher die Wickelköpfe der nur je einen Zahn umfassenden Spulen auf der dem Kommutator abgewendeten Seite durch die Verbindung je zweier der gleichen Lage angehörender und sich nicht kreuzender Stäbe hergestellt sind.DC auxiliary winding for the rotor of a compensated asynchronous motor with a greatly shortened winding step In the main patent 452 o74 there is one as an auxiliary winding DC winding used for compensated asynchronous motors with a greatly shortened Winding step indicated in which the end windings of the each encompassing only one tooth Coils on the side facing away from the commutator by connecting two each rods belonging to the same layer and not crossing each other are made.
Die Erfindung betrifft eine Weiterbildung dieser Wicklung im Sinne einer weiteren. Verbesserung der Kommutierung, wodurch die Wicklung auch für sehr große Maschinen geeignet wird. Zu diesem Zwecke wird die Wicklung mit verkürzten Stäben ausgeführt. Die verkürzten Stäbe reichen von der Kommutatorseite aus beispielsweise nur bis zur-Hälfte oder einem Drittel der Nutlänge. Die sie daselbst verbindenden Wickelköpfe sind in radialen Lüftungsschlitzen oder in sonstigen vorhandenen Kühlkanälen oder entsprechenden Vertiefungen untergebracht.The invention relates to a further development of this winding in the sense another. Improvement of the commutation, which makes the winding also for a lot large machines. For this purpose the winding is shortened with Executed rods. The shortened bars extend from the commutator side, for example only up to half or a third of the groove length. Those connecting them there Winding heads are in radial ventilation slots or in other existing cooling channels or corresponding wells housed.
Die Zeichnung zeigt drei Ausführungsbeispiele.The drawing shows three exemplary embodiments.
Bei dem Ausführungsbeispiel der Abb. I ist der die Wicklung tragende Maschinenteil - der umlaufende Primärteil eines kompensierten Asynchronmotors - durch radiale Lüftungsschlitze e in drei Blechpakete a, b und c mit den schraffiert dargestellten Zähnen z unterteilt. Die Abstandhalter d sind in dem die Blechpakete a und b trennenden Luftschlitz mit Aussparungen, Löchern o. dgl. versehen, um die Wickelköpfe f für die mit Kammutator k versehene Hilfswicklung von einer Nut zur nächsten führen zu können. Die Hilfswicklung ist hier beispielsweise gemäß der Abb. 3 des Hauptpatents 452 o74 ausgeführt. Jede Spule enthält zwei Windungen, beispielsweise I, 3' und 2, 4', die an je einen Kommutatorsteg angeschlossen sind.In the embodiment of Fig. I, the one carrying the winding Machine part - the rotating primary part of a compensated asynchronous motor - through radial ventilation slots e in three sheet metal stacks a, b and c with the hatched teeth shown z divided. The spacers d are in which the laminated cores a and b separating air slot with recesses, holes o. The like. Provided to the Winding heads f for the auxiliary winding provided with Kammutator k from a groove to next to be able to lead. The auxiliary winding is here, for example, according to Fig. 3 of the main patent 452 o74 executed. Each coil contains two turns, for example I, 3 'and 2, 4', which are each connected to a commutator bar.
In der Abb. 2 ist eine Wicklung mit einer einzigen Windung pro Spule angegeben. Es ist ohne weiteres zu ersehen, daß in diesem Fall die zwei in einer Nut liegenden Stäbe 2 und 3 bzw. 4 und 5 zu einem einzigen Stab vereinigt werden können. Diese Vereinigung ändert nichts an der Flußverkettung und an der Kommutierung, führt jedoch zu einer Kupferersparnis und demzufolge zu kleineren Kupferverlusten, da nunmehr jeder Stab nur während derjenigen Zeit von Strom durchflossen ist, während welcher sein zugehöriger Kollektorsteg an einer Bürste vorbeistreicht.In Fig. 2 is a winding with a single turn per coil specified. It can be readily seen that in this case the two in one Groove lying rods 2 and 3 or 4 and 5 are combined into a single rod can. This union does not change the flux linkage and the commutation, however leads to a copper saving and consequently to smaller copper losses, since now every rod is only flowed through by current during that time during which its associated collector bar brushes past a brush.
Abb. 3 zeigt die Wicklung nach Abb. 2 mit vereinigten Stäben in der Nut. Die Wickelköpfe f dieser Wicklung können in Form eines einfachen durchlaufenden Kupferringes ausgeführt werden.Fig. 3 shows the winding according to Fig. 2 with united bars in the Groove. The winding heads f of this winding can be in the form of a simple continuous Copper ring.
