Description

Zur Erzielung einer gleichmäßigen Stromaufteilung auf die einzelnen parallel geschalteten Bürsten am Umfang des Kommutators von Gleich- oder Wechselstrommaschinen mit Kommutatortrommelwicklung kann man eine das aktive Eisen des Läufers umschlingende, in sich geschlossene Hilfsringwicklung vorsehen, deren Außenleiter in den Nuten der Hauptwicklung, und zwar zweckmäßig unterhalb dieser, untergebracht sind. Die Windungen der Hilfsringwicklung sind über den Ankerumfang derart (z. B. gleichmäßig) verteilt, daß die gesamte Induktion der dieRingwicklung durchsetzenden Xutzflüsse innerhalb dieser gleich Null ist. Die Hilfsringwicklung wirkt dann auf die Nutenstreuflüsse der kommutierenden Spulen der Hauptwicklung als Dämpferwicklung.To achieve an even distribution of current to the individual parallel-connected Brushes on the circumference of the commutator of DC or AC machines with a commutator drum winding can be one provide a self-contained auxiliary ring winding that wraps around the active iron of the rotor, the outer conductors of which are accommodated in the grooves of the main winding, specifically below this. The turns of the auxiliary ring winding are distributed over the armature circumference in such a way (e.g. evenly) that that the entire induction of the useful fluxes penetrating the ring winding is within this is zero. The auxiliary ring winding then acts on the slot leakage fluxes commutating coils of the main winding as a damper winding.

Die Erfindung betrifft eine Verbesserung dieser Anordnung insofern, als die Ausbildung eines dämpfenden Kurzschlußstromes in der Hilfsringwicklung durch Verminderung ihres Widerstandes unterstützt wird. Erfindungsgemäß ist die Hilfsringwicklung an einen besonderen Hilfskommutator angeschlossen, auf dem Bürsten derart verteilt und angeordnet sind, daß diejenigen Windungen der Hilfsringwicklung, die mit den kommutierenden Spulen der Hauptwicklung in denselben Nuten liegen, durch die Bürsten am Hilfskommutator kurzgeschlossen werden. Der Kurzschlußstrom kann sich also unmittelbar in den vom Nutenstreufluß der kommutierenden Spulen der Hauptwicklung durchsetzten Windungen der Hilfsringwicklung schließen, ohne die anderen Windungen bzw. Verbindungsleitungen durchfließen zu müssen. Abb. ι und 2 der Zeichnung zeigen zur Veranschaulichung der Erfindung den Läufer einer Kommutatormaschine im axialen und im Nutenquerschnitt, ι ist die Kommutatorhauptwicklung, 2 die in denselben Nuten untergebrachte, das Jocheisen umschlingende Ringwicklung, deren einzelne Windungen an die Segmente eines Hilfskommutators 3 angeschlossen sind. Die auf dem Hilfskommutator schleifenden Bürsten 4 sind in der geschilderten Weise angeordnet und ausgebildet. Die Bürsten 4 sind zur Verbesserung des Kurzschlusses zweckmäßig Metallbürsten.The invention relates to an improvement in this arrangement in that the design a damping short-circuit current in the auxiliary ring winding is supported by reducing its resistance. According to the invention, the auxiliary ring winding is connected to a special auxiliary commutator, are distributed and arranged on the brushes so that those turns of the auxiliary ring winding that with the commutating Coils of the main winding are in the same slots that short-circuit the brushes on the auxiliary commutator. The short-circuit current can therefore directly affect the commutating from the slot leakage flux Windings of the auxiliary ring winding interspersed with the coils of the main winding close without the other turns or windings. To have to flow through connecting lines. Fig. Ι and 2 of the drawing show for illustration the invention the rotor of a commutator machine in the axial and in the slot cross-section, ι is the main commutator winding, 2 the ring winding, which is housed in the same grooves and wrapped around the yoke iron, with its individual turns the segments of an auxiliary commutator 3 are connected. The one on the auxiliary commutator Abrasive brushes 4 are arranged and designed in the manner described. The brushes 4 are suitably metal brushes to improve the short circuit.
