Description

Verfahren zum Isolieren von elektrischen Spulen Es ist bekannt, dünne schmelzbare Platten oder Streifen aus Isolierstoff beim Wickeln von Spulen für elektrische -Maschinen und Apparate auf die einzelnen Windungslagen aufzulegen, derart, daß sie von den auf diese aufgespulten erhitzten Win- dungen der folgenden Lage zwischen die Lücken, die sich zwischen den leiden Lagen bilden, gedrückt werden. Da die einzelnen Windungen der Spule bereits isoliert sind. handelt es sich hei diesem Verfahren lediglich darum. die Lücken zwischen den eng aneinanderliegenden Windungen auszu- füllen wid so die die elektrische Festigkeit herab- setzenden Hohlräume zu beseitigen. Die l;rfindting macht zwar von einem ähnlichen Verfahren Gebrauch, sie hat jedoch die Aufgabe, die lagenweisc gewickelten Spulen die einzelnen \\'ickluiigeii gegeneinander auf einfachere Weise als bisher zti isolieren. Bei dem erfindungsgemäßen Verfahren zum Isolieren von elektrischen Spulen werden zwischen die einzelnen nicht isolierten Windungen leim Wickeln Fäden aus thermoplastischem, elektrischisolierendem Material, beispielsweise aus Polystyrol, eingelegt und durch Wärmeanwendung und Zusammenpressen der Windungslagen der gewickelten Spule in Richtung der Spulenachse derart flachgedrückt, daß das Fadenmaterial den gesamten Z\visclienrattm zwischen den einzelnen Windungen und gegebenenfalls Lagen ausfüllt.Method for isolating electrical coils It is known to be thin fusible plates or Strips of insulating material when winding coils for electrical machines and apparatus on the lay individual turns in such a way that from the heated winds coiled on connections of the following position between the gaps, that form between the suffering layers, pressed will. Because the individual turns of the coil are already isolated. it is called this Procedure only about it. the gaps between the closely spaced turns fill the electrical strength down to eliminate settling cavities. The l; rfindting makes of a similar one Procedure, but it has the task of the coils wound in layers the individual \\ 'ickluiigeii against each other in a simpler way isolate zti than before. In the method according to the invention for insulating electrical coils, threads made of thermoplastic, electrically insulating material, for example made of polystyrene, are inserted between the individual non-insulated windings and pressed flat in the direction of the coil axis in such a way that the thread material fills the entire Z \ visclienrattm between the individual turns and possibly layers.

Die Erfindung bietet den Vorteil, daß zwei bisher getrennte Verfahren, nämlich das Isolieren der Leiter durch Umspinnen, Überziehen mit Lack od. dgl. und das Wickeln der Spule auf ein einziges Verfahren zusammengedrängt sind, wodurch sich eine erliehliche Vereinfachung und Verbilligung in der Herstellung derartiger Spulen ergeben. Außer-(lern kann die Isolationsstärke auf ein Mindestmaß herabgesetzt werden, ohne daß eine Beschädigung durch mechanische Beanspruchung beim Wickeln zu befürchten ist.The invention offers the advantage that two previously separate processes namely the isolation of the conductor by spinning, coating with paint or the like. And the winding of the coil are compressed on a single process, thereby an available simplification and cheaper in the production such coils result. The insulation thickness can also be learned to a minimum can be reduced without damage from mechanical stress is to be feared when swaddling.
