Description

Schaltung zweier als Generator und Motor laufenden Gleichstrommaschinen mit mehrfachen Bürsten. Die dem Hauptpatent zugrunde liegende Ausführungsform leidet unter dem Übelstand, daß zur Erzielung eines minimalen Kommutierungsstromes eine entsprechende Erhöhung der Bürstenzahl erforderlich ist. Nach der vorliegenden Erfindung wird bei der KommutatIon ein Minimum der Reaktanzspannung erzielt, .ohne die Anzahl der Bürsten ung emessen zu steigern.Connection of two DC machines running as a generator and a motor with multiple brushes. The embodiment on which the main patent is based suffers under the disadvantage that to achieve a minimal commutation current a a corresponding increase in the number of brushes is required. According to the present invention a minimum of the reactance voltage is achieved during the commutation, without the number the brushing ability to increase.

Bei dieser Erfindung befinden sich auf dem Anker des Generators. sowie auch auf dem Anker des Motors zwei odermehr voneinander elektrisch unabhängige Wicklungen. Jede Wicklung hat ihren besonderen Stromwender mit zugehörigem, ebenfalls elektrisch unabhängigem Bürstensystem.In this invention are located on the armature of the generator. as also on the armature of the motor two or more electrically independent windings. Each winding has its own commutator with an associated one, also electrical independent brush system.

Dabei werden. vorzugsweise die verschiedenen Ankerwicklungen s,o ,ausgeführt, daß ihre magnetische Abhängigkeit vom Felde möglichst gleich wird und daß eine möglichst enge gegenseitige elektromagnetische Beeinflussung zwischen den Leitern, welche die Kommutierungsströme der verschiedenen Bürstensysteme- führen, erzielt wird.Be there. preferably the various armature windings s, o, executed, that their magnetic dependence on the field is as equal as possible and that one as possible close mutual electromagnetic interference between the conductors, which the commutation currents of the various brush systems lead, is achieved.

Somit wird die Energie der Selbstindukti:onsfelder der Kömmutierungsströme in ihrem größten Teile nicht zwischen Stromwender und" Bürste frei, sondern sie wird in bedeutendem Maße infolge gegenseitiger Induktion auf andere Systeme übergehen. Wenn nun die Kommutation in den magnetisch verketteten Systemen Stromänderungen zur Folge hat, die in entgegengesetzter Richtung auf das Feld ihrer gegenseitigen Induktion einwirken, so wird diese Einwirkung eine große Erniedrigung der Reaktanzspannung veranlassen, und wenn eine genügend enge Verkettung vorhanden ist, so wird die Reaktanzspannungem Minimum werden.Thus the energy of the self-induction fields becomes the commutation currents for the most part not between commutator and "brush free, but them will migrate to other systems to a significant extent as a result of mutual induction. If now the commutation in the magnetically linked systems current changes has the consequence that the opposite direction on the field of their mutual If induction act, this action will greatly decrease the reactance voltage cause, and if there is a sufficiently close concatenation, the reactance voltages will be em Become a minimum.

Die Zeichnung stellt zwei Ausführungsbeispiele dies Erfindungsgegenstandes dar. Gemäß Abb. i besitzen der Generator G und der Motor M, deren Erregerwicklungen mit F, und F@ bezeichnet sind, je zwei Ankerwicklungen gleicher Bauart, von denen jede mit zwei Stromwendern versehen ist. Beide Stromwender sind so gegeneinander verdreht, daß die äquipotentiellen Bürsten, die zu verschieaenen Systemen gehören, auch eine verschiedene Stellung relativ zu den angrenzenden Stromwenderstegen einnehmen. Im vorliegenden Falle sind die Stromwender um -eine halbe Stegoteilung gegeneinander verdreht. Jede Bürste des Motors ist mit einer entsprechenden Bürste des Generators verbunden.The drawing represents two exemplary embodiments of this subject matter of the invention According to Fig. i, the generator G and the motor M have their excitation windings with F, and F @ are designated, two armature windings of the same type, of which each is provided with two commutators. Both commutators are so against each other twisted so that the equipotential brushes belonging to different systems, also assume a different position relative to the adjacent commutator bars. In the present case, the commutators are half a bar pitch against each other twisted. Each brush on the motor is linked to a corresponding brush on the generator tied together.

Man ersieht hier, daß, wenn der Strom in einem Wicklungsteile sich z. B. erhöht, sich der Strom ian entsprechenden, mit dem ersten sehr eng verketteten Wicklungsteile des anderen Systems vermindert, so daß das gesamte Streufeld, welches von beiden Strömen abhängig ist, praktisch konstant bleibt.It can be seen here that when the current is in a winding part z. B. increases, the current ian corresponding, with the first very closely linked Winding parts of the other system reduced, so that the entire stray field, which depends on both currents, remains practically constant.

In Abb. 2 ist eine Ausführungsform schematisch dargestellt, welche drei unter sich elektrisch unabhängige Ankerwicklungen 1Z, 12' und R" mit zugehörigen Stromwendern und Bürsten besitzt. Alles, was von der Ausführungsform mit zwei Ankerwicklungen gesagt wurde, gilt auch. ohne weiteres für die Ausführungsform mit drei Ankerwicklungen.In Fig. 2 an embodiment is shown schematically, which three electrically independent armature windings 1Z, 12 'and R "with associated Owns commutators and brushes. Everything from the embodiment with two armature windings was said also applies. readily for the embodiment with three armature windings.
