Bei Ankerwicklungen aus Aluminiumdraht besteht die Schwierigkeit, die Spulenenden mit den Stromwenderstegen, zu verbinden, weil Lötverbindungen zwischen Aluminium und Kupfer schwer herzustellen und überdies nicht korrosionsbeständig sind. Um diese Schwierigkeiten zu vermeiden, werden gemäß der Erfindung an. die Enden der Aluminiumstäbe Stücke aus einem Werkstoff angeschweißt, der sich mit den Stromwender-Stegen leicht verlöten läßt. Zweckmäßig1 werden Stücke aus Kupfer verwendet.With armature windings made of aluminum wire, the difficulty arises in connecting the coil ends with the commutator bars, because soldered connections between aluminum and copper are difficult to make and, moreover, are not corrosion-resistant. In order to avoid these difficulties, according to the invention. the ends of the aluminum rods welded on pieces made of a material that can be easily soldered to the commutator bars. Suitably 1 pieces are used of copper.

In der Zeichnung ist beispielsweise ein Ausschnitt aus einem nach dem Verfahren gemäß der Erfindung hergestellten Anker einer elektrischen Anlaßmas chine für Brennkraftmaschinen dargestellt, α ist der lamellierte Blechkörper. Der Anker ist mit einer Stabwicklung b aus Aluminium bewickelt. An die aus dem Blechkörper vorstehenden Enden der Aluminiiumwicklungsstäbe c sind Stabstücke d aus Kupfer angeschweißt. Die freien Enden der Kupferstücke sind in die Lamellene des Stromwenders / eingelötet. Die Kupferstabstücke ,werden zweckmäßig elektrisch an die Stabenden der Aluminiumwicklung angeschweißt. Das Verfahren ist vorzugsweise bei Stabwicklungen anwendbar.In the drawing, for example, a section of an armature manufactured by the method according to the invention of an electrical An Anlaßmas chine for internal combustion engines is shown, α is the laminated sheet metal body. The armature is wound with a rod winding b made of aluminum. Rod pieces d made of copper are welded to the ends of the aluminum winding rods c protruding from the sheet metal body. The free ends of the copper pieces are soldered into the lamellae of the commutator /. The copper rod pieces are expediently electrically welded to the rod ends of the aluminum winding. The method is preferably applicable to bar windings.
