 EMI2.1 
 Kraft zweier Leiter wirkt. Die Bürsten müssen also getrennten elektrischen Stromkreisen angehören. 



   Wie dies z. B. bei einem gewöhnlichen Repulsionsmotor erreicht wird, zeigt Fig. 2.   S ist   die Statorwicklung, R der Rotor, dessen Wicklung der Einfachheit halber hier als Ringwicklung dargestellt ist, statt dessen könnte ebensogut eine Trommelwicklung verwendet werden. K1 und K2 sind die beiden Kommutatoren, von denen hier einer ausserhalb, der andere innerhalb des Rotors dargestellt ist. Die kurzgeschlossenen Bürstenpaare jedes Kommutators sind, wie erwähnt, nicht miteinander verbunden. Ebenso lässt sich ein Repulsionsmotor mit zwei Bürstenpaaren pro Polpaar auf jedem Kommutator ausführen. Fig. 3 zeigt analog einen Serienmotor. Hier ist F die Feldmagnetwicklung, C die   Kompensationswicklung,   T, die primäre und T2.

   T2 zwei sekundäre Wicklungen eines Hauptschlusstransformators, von denen je eine den Bürsten eines der beiden Kommutatoren   Ki   und K2 den Strom zuführt. Die Windungszahl des Transformators kann regelbar gemacht werden. Die beiden Kommutatoren erhalten die halbe Länge von dem einer Maschine

   Wechselstrom-Kommutatormaschine mit zwei Kommutatoren, deren Segmente an die beiden Seiten derselben Ankerwicklung angeschlossen sind. dadurch gekennzeichnet, dass die Ankerstromkreise, die von den Bürsten jeder der beiden Kommutatoren für sich gebildet werden. dadurch unabhängig voneinander gemacht sind, dass die gleichnamigen Bürsten des einen Kommutators durch keine äussere Verbindung mit denen des anderen Kommutators verbunden sind, wobei gleichnamige Bürsten der beiden Kommutatoren so eingestellt sind. dass sie in ihrer    n > lativen Lage zu   den Segmenten der beiden Kommutatoren um etwa eine halbe Segmentteilung   verschoben sind (Fig. l).

 EMI2.1
 The power of two conductors works. The brushes must therefore belong to separate electrical circuits.



   How this z. B. is achieved in an ordinary repulsion motor, Fig. 2. S is the stator winding, R the rotor, the winding of which is shown here as a ring winding for the sake of simplicity, instead a drum winding could just as well be used. K1 and K2 are the two commutators, one of which is shown here outside the rotor and the other inside. As mentioned, the short-circuited pairs of brushes of each commutator are not connected to one another. A repulsion motor can also be implemented with two pairs of brushes per pair of poles on each commutator. 3 shows a series engine by analogy. Here F is the field magnet winding, C is the compensation winding, T is the primary and T2.

   T2 two secondary windings of a main circuit transformer, one of which each feeds the current to the brushes of one of the two commutators Ki and K2. The number of turns of the transformer can be made adjustable. The two commutators are half the length of one machine

1.

   AC commutator machine with two commutators, the segments of which are connected to the two sides of the same armature winding. characterized in that the armature circuits which are formed by the brushes of each of the two commutators for themselves. are made independent of one another in that the brushes of the same name of one commutator are not connected to those of the other commutator by any external connection, with brushes of the same name on the two commutators being set in this way. that they are shifted in their n> lative position to the segments of the two commutators by about half a segment division (Fig. 1).
