  Spulen- bzw. Halbspulenwicklung für elektrische Maschinen 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 be Halbspule dargestellt, jedoch mit Ausführungen V, die   durch "Kupfer-Aluminium-Stäbe" an   beiden Enden gebildet werden. Fig. 4 stellt eine Halbspule einer Wellenwicklung dar, deren Leiter selbst durch   "Kupfer-Aluminium-Stäbe" gebildet   werden. In Fig. 5 ist eine Spulenausführung der Schleifenwicklung aus Leitern dargestellt, die selbst durch "Kupfer-Aluminium-Kupfer-Stäbe" mit einem Kupferteil C an den Enden gebildet werden, wobei der Aluminiumteil sich über die übrige Spulenlänge erstreckt.

   Fig. 6 zeigt eine Halbspulenausführung einer Schleifenwicklung aus Leitern, die selbst   durch "Kupfer-Alumi-     nium-Kupfer-Stäbe"gebildet   werden, gleichfalls mit dem Kupferteil an den Spulenenden und mit dem Aluminiumteil   A,- welcher   den mittleren Teil des Halbspulenleiters bildet. 



   Die Erfindung bietet eine Lösung, die es ermöglicht, anstatt des in aller Welt mangelnden Kupfers, Aluminium und dessen Legierungen zu verwenden, bei gleicher Art des Spulenanschliessens wie bei solchen aus Kupferleitern hergestellten Wicklungen. Die mehr Arbeitsaufwand erfordernde Aluminiumleiterausführung wird durch ein kleineres Gewicht der Maschine und durch den niedrigen Aluminiumpreis ausgeglichen. Die erfindungsgemässe Ausführung eignet sich besonders für Ankerwicklungen von Gleichstrommaschinen.

  Coil or half-coil winding for electrical machines
 EMI1.1
 

 <Desc / Clms Page number 2>

 be half-coil shown, but with versions V, which are formed by "copper-aluminum rods" at both ends. Fig. 4 shows a half-coil of a wave winding, the conductors of which are themselves formed by "copper-aluminum rods". 5 shows a coil design of the loop winding made of conductors which are themselves formed by "copper-aluminum-copper rods" with a copper part C at the ends, the aluminum part extending over the remaining coil length.

   6 shows a half-coil design of a loop winding made of conductors which are themselves formed by "copper-aluminum-copper rods", likewise with the copper part at the coil ends and with the aluminum part A, which forms the middle part of the half-coil conductor.



   The invention offers a solution which makes it possible to use aluminum and its alloys instead of copper, which is in short supply all over the world, with the same type of coil connection as with windings made from copper conductors. The aluminum ladder design, which requires more work, is offset by the lower weight of the machine and the low price of aluminum. The embodiment according to the invention is particularly suitable for armature windings of direct current machines.

PATENTANSPRUCH : Spulen- bzw. Halbspulenwicklung für elektrische Maschinen mit Leitern aus Aluminium oder Aluminiumlegierungen, wobei die Leiterenden für die gegenseitige Verbindung bzw. den Anschluss an andere elektrische Teile (Kupferteile) der Maschine mit Kupferanschlussteilen versehen sind, dadurch gekennzeichnet, dass an die Enden des Spulen- bzw. Halbspulenleiters gesondert hergestellte "Kupfer-Aluminium-Stäbe" (aus jeweils den ganzen Stabquerschnitt einnehmenden Kupfer- bzw. Aluminiumteilen zusammengesetzte Stäbe) mit ihrem Aluminiumteil angeschlossen oder die Spulen bzw. die stabförmigen Halbspulenleiter selbst durch "Kupfer-Aluminium-Stäbe" bzw. "Kupfer-Aluminium-Kupfer-Stäbe" gebildet sind. PATENT CLAIM: Coil or half-coil winding for electrical machines with conductors made of aluminum or aluminum alloys, the conductor ends being provided with copper connection parts for the mutual connection or connection to other electrical parts (copper parts) of the machine, characterized in that the ends of the coil or half-coil conductors separately produced "copper-aluminum rods" (rods composed of copper or aluminum parts each taking up the entire rod cross-section) connected to their aluminum part or the coils or the rod-shaped half-coil conductors themselves by "copper-aluminum rods" or "Copper-aluminum-copper rods" are formed.
