Mit anderen Worten : Man erhält bei mässigem Aufwand an Ankerkupfer einen erhöhten Wirkungsgrad und eine erhebliche Leistungssteigerung des Einankerumformers gegenüber den bekannten Ausführungen.
Da die Ursache für die zusätzliche Stromwärme hauptsächlich in der Nutenstreuung zu suchen ist und diese am Nutenrande wesentlich grössere Werte als am Nutengrunde annimmt, ist es bei solchen Ankerwicklungen, bei denen die Leiter in zwei Schichten angeordnet sind, in vielen Fällen ausreichend, wenn man die den Wechselstromzuleitungen zunächst liegenden Ankerleiter nur in der dem Nutenrande zugekehrten Schicht durch geeignete Massnahmen gegen zusätzliche Stromwärme schützt. Die Ausführung der Ankerwicklung wird dadurch noch einfacher und billiger.
PATENT-ANSPRÜCHE :
1. Ankerwicklung für Einankerumformer, dadurch gekennzeichnet, dass diejenigen Ankerleiter, an welche die Wechselstromzuleitungen angeschlossen sind, sowie je nach Bedarf auch die beiderseits benachbarten Ankerleiter (beispielsweise durch Unterteilung, Verdrillung oder Verschränkung) gegen Erwärmung durch zusätzliche Stromwärme, die durch Nutenstreuung und Hautwirkung erzeugt wird, geschützt sind, die übrigen Ankerleiter dagegen nicht.

In other words: with a moderate amount of armature copper, an increased efficiency and a considerable increase in performance of the single armature converter are obtained compared to the known designs.
Since the cause of the additional current heat is mainly to be found in the slot scatter and this takes on significantly higher values at the edge of the slot than at the bottom of the slot, it is sufficient in many cases to use the The armature conductor initially lying next to the alternating current supply lines only protects the layer facing the edge of the groove against additional heat by means of suitable measures. This makes the armature winding even easier and cheaper.
PATENT CLAIMS:
1. Armature winding for single-armature converters, characterized in that those armature conductors to which the alternating current supply lines are connected and, if required, the armature conductors adjacent on both sides (for example, by subdivision, twisting or entanglement) against heating by additional current heat generated by groove scattering and skin effect is protected, the other anchor conductors are not.
