 <Desc/Clms Page number 2> 

   zwei Phaseuxuleitungen   von der Wicklung 1 zu den   Kontakten 4 gcgenÜber   den Zuleitungen zu den Kontakten 3 miteinander vertauscht. 



   Die Umschaltung der Ständerwicklung um   180  in   der Phase kann entweder wie dargestellt durch unmittelbare Umschaltung der Ständerwicklung herbeigeführt werden, man kann aber auch bei Reihenschlussmotoren mit Zwischentransformator entweder die Primär- oder die   Sekundärwicklung   des Zwischentransformators um   1800 umschalten.   



     PATENT-ANSPRÜCHE   :
1. Verfahren zum Umsteuern von Drehstrom-Reihenschluss-Kommutatormotoren wechselnden
Drehrichtung mittels Bürstenverschiebung, dadurch gekennzeichnet, dass die Bürsten des Motors zur Herstellung der einen Drehrichtung in   üblicher Weise aus   der Nullstellung in Richtung der   Kurzschlussstellung verschoben   werden, und dass zur Umkehr der Drehrichtung die Bürsten in die Kurzschlussstellung gebracht werden, die   Ständerwicklung   um   1800 in   der Phase um- geschaltet wird und die Bürsten nunmehr in Richtung der früheren Nullstellung   (jetzt   Kurz- schlussstellung) zurückgezogen werden.

  Procedure for reversing three-phase series commutator motors with alternating direction of rotation.
 EMI1.1
 

 <Desc / Clms Page number 2>

   two phaseuxu lines from winding 1 to contacts 4 are interchanged via the feed lines to contacts 3.



   Switching the stator winding by 180 in phase can either be brought about by switching the stator winding immediately, as shown, but you can also switch either the primary or secondary winding of the intermediate transformer by 1800 in series motors with an intermediate transformer.



     PATENT CLAIMS:
1. Procedure for reversing alternating three-phase series commutator motors
Direction of rotation by means of brush displacement, characterized in that the brushes of the motor to produce one direction of rotation are moved in the usual way from the zero position towards the short-circuit position, and that the brushes are brought into the short-circuit position to reverse the direction of rotation, the stator winding by 1800 in the Phase is switched and the brushes are now withdrawn in the direction of the previous zero position (now short-circuit position).

2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass das Verschieben der Bürsten durch den Motor selbst (über ein Getriebe) herbeigeführt wird. EMI2.1 2. The method according to claim 1, characterized in that the displacement of the brushes is brought about by the motor itself (via a gear). EMI2.1
