 <Desc/Clms Page number 2> 

 elektrischen Maschinensungsmittelfreien Giessharz durch den Nutenschlitz 4 in die Nut eingespritzt. Zu diesem Zweck kann beispielsweise eine mit einem Druckkolben 5 versehene Spritzeinrichtung 6 verwendet werden. die mit Giessharz 7 in plastischer Form gefüllt ist und ein Ansatzrohr 8 für das Einspritzen der Füllmasse aufweist. 



  Nachdem sämtlicheDrahtlagen 1 mit den Zwischenlagen aus Giessharz in die Statornuten eingebracht und die Nuten abgeschlossen sind, wird der fertig gewickelte Stator in einem Ofen ausgetrocknet. Durch die Verwendung einer Füllmasse aus   härtbarem, lösungsmittelfreiem Giessharz entstehen   durch die Wärmebehandlung des Stators keine Luftzwischenräume.

 <Desc / Clms Page number 2>

 electrical machine solvent-free casting resin is injected through the slot 4 into the slot. For this purpose, for example, a spray device 6 provided with a pressure piston 5 can be used. which is filled with casting resin 7 in plastic form and has an attachment tube 8 for injecting the filling compound.



  After all wire layers 1 with the intermediate layers made of cast resin have been introduced into the stator slots and the slots have been closed, the fully wound stator is dried out in an oven. By using a filler made of curable, solvent-free casting resin, the heat treatment of the stator does not create any air gaps.

PATENTANSPRUCH : Verfahren zur herstellung von Statorwicklungen für elektrische Maschinen mit halbgeschlossenen Nuten, insbesondere Hochspannungsmaschinen kleiner Leistung, bei welchem die Wicklungsdrähte einzeln in die Statornuten eingelegt und mittels Nutverschlüssen festgehalten werden, dadurch gekennzeichnet, dass nach dem Einlegen jeder Drahtlage in die Statornut ein aushärtbares, lösungsmittelfreies Giessharz in die Statornut unter Druck eingespritzt wird, und, nachdem alle Wicklungslagen eingelegt sirih deze Nutenverschluss hergestellt worden ist, der ganze Stator einer Wärmebehandlung'mterworfen wird. PATENT CLAIM: A method for producing stator windings for electrical machines with semi-closed slots, in particular high-voltage machines with low power, in which the winding wires are individually inserted into the stator slots and held in place by slot locks, characterized in that, after each wire layer has been inserted into the stator slot, a hardenable, solvent-free casting resin is in the stator slot is injected under pressure and, after all winding layers have been inserted and the slot seal has been produced, the entire stator is subjected to a heat treatment.
