  Dreiphasen-Kollektormotor mit Kompensationswicklung. 



   Da die Kompensationswicklung eines Kollektormotors in allen Fällen das Spiegelbild der   Rotorwicklung   sein soll,   so liegt hei Anwendung   der Kompensationswicklung auf eine Dreiphasen-Kollektormaschine am nächsten, diese Kompensationswicklung der Ankerwicklung ähnlich zu gestalten, d. h. auf den Stator eine eschlossene Wicklung mit derselben Leiterzahl wie die der   Rotorwieklung zu legen.

   Da die Rotorwicklung aber   eine Dreieckschaltung darstellt, so kann die so ausgeführte Kompensationswicklung nicht unmittelbar in   Reihe mit   der   Rotorwicktung geschaltet. sondern   muss mit ihr durch einen Serien-Trans-   formater     verknüpft   werden.   Die Beigabe eines solchen besonderen Transformators   ist aber natürlich unerwünscht, ihn zu vermeiden und   trotzdem eine Kompensationswicklung   zu 
 EMI1.1 
 der nachfolgend beschriebenen neuen Schaltung.

   Im wesentlichen besteht dieselbe in der Anwendung einer unmittelbar mit der Rotorwicklung in   Serie geschatteten Kompensations-   wicklung, die in besonderer weise bemessen und derart ausgeführt wird, dass   Wicklungs-     abteilungen des Ankers, deren Leiter Ströme verschiedener Phase führen, durch Ströme   nur einer Phase im Stator kompensiert werden. 
 EMI1.2 
   der beiden Kinzetströme in   jeder Ankernut kann also ersetzt werden durch den Netzstrom.   1,   mit anderen Worten : den beiden Leitern in jeder Nut entspricht ein Leiter der 
 EMI1.3 
 nur   onen   Leiter enthalten, wie der Einfachheit wegen angenommen wurde, sondern ein beliebiges Vielfaches.

   Um ferner das Feld im Anker vollständig aufzuheben, wird man in bekannter Weise der   Komponsationswicklung     zweckmässig einen mässigen Überschuss geben,   so dass in diesem Sinno das oben gefundene Verhältnis der Leiterzahlen der Kompensationswicklung und der Leiterwicklung nur als annähernd zu bezeichnen ist. 



   Die räumliche Verteilung der Kompensationswicklung einer Phase ergibt sich nach Fig. 2, wo f den Rotor, c die Kompensationswicklung und b die zu der Phase gehörende Bürste bedeutet. Um auch an der Auflagestelle der Bürste ein zum Stromwenden geeignetes Feld zu schaffen, können besonders mit den Leitern c in Reihe geschaltete Leiter w vorgesehen sein.

  Three-phase collector motor with compensation winding.



   Since the compensation winding of a collector motor should in all cases be the mirror image of the rotor winding, when applying the compensation winding to a three-phase collector machine, it is closest to designing this compensation winding similar to the armature winding, i.e. H. to place a closed winding on the stator with the same number of conductors as that of the rotor.

   However, since the rotor winding is a delta connection, the compensation winding constructed in this way cannot be connected directly in series with the rotor winding. it has to be linked to it by a serial transformer. The addition of such a special transformer is of course undesirable, avoiding it and still adding a compensation winding
 EMI1.1
 the new circuit described below.

   Essentially, the same consists in the use of a compensation winding directly shaded with the rotor winding in series, which is dimensioned in a special way and designed in such a way that winding sections of the armature, whose conductors carry currents in different phases, through currents of only one phase in the stator be compensated.
 EMI1.2
   the two Kinzet currents in each armature groove can be replaced by the mains current. 1, in other words: the two conductors in each slot correspond to one conductor of the
 EMI1.3
 contain only one ladder, as was assumed for the sake of simplicity, but an arbitrary multiple.

   Furthermore, in order to completely cancel the field in the armature, it is advisable to give the compensation winding a moderate excess in a known way, so that in this sense the ratio of the number of conductors of the compensation winding and the conductor winding found above can only be described as approximate.



   The spatial distribution of the compensation winding of a phase is shown in FIG. 2, where f denotes the rotor, c the compensation winding and b the brush belonging to the phase. In order to create a field suitable for current reversal at the contact point of the brush, conductors w connected in series with the conductors c can be provided.
