Description
Wickelkopfbandage für elektrische MaschinenHead bandage for electrical machines
Die Wickelköpxe elektrischer Maschinen werden bekanntlich mit Bandagen versehen, wofür man heute weitgehend thermoplastische Kunststoffe verwendet. Für Maschinen mit einer üblichen Erwärmung um etwa 130° C herum sind derartige Kunststoffbandagen ohne weiteres geeignet. Handelt es sich jedoch um Maschinen mit höherer Erwärmung - bei Elektromotoren mit Motorvollschutz sind kurzzeitig Temperaturen bis 250° C zulässig - , dann besteht die Gefahr, daß die Bandage aus thermoplastischem Kunststoff schmilzt, aufplatzt und unter Umstän-.u^ Teile derselben in den Luftspalt zwischen Ständer und Läufer gelangen.The winding heads of electrical machines are known to have Bandages are provided, for which thermoplastic plastics are largely used today. For machines with normal heating Such plastic bandages are around 130 ° C readily suitable. However, when it comes to machines with higher temperatures - electric motors with full motor protection short-term temperatures of up to 250 ° C are permissible -, then there is a risk that the bandage is made of thermoplastic material melts, bursts and, under certain circumstances, parts of it get into the air gap between the stator and rotor.
Es gibt zwar hochtemperaturbeständige Bandagen aus Glasfasern, deren Herstellung jedoch sehr aufwendig und teuer ist, da die einzelnen Glasfasern untereinander verflochten und noch zusätzlich imprägniert werden müssen.There are high-temperature-resistant bandages made of glass fibers, but their production is very complex and expensive because the individual glass fibers intertwined with each other and additionally have to be impregnated.
Die Neuerung schafft hier dadurch Abhilfe, daß die Bana r- aus einer mit thermoplastischem Kunststoff umhüllten GO p.«=--' ajerseele besteht. Zweckmäßig wird dabei die Seele von ei--.r Anzahl unverflochtener Glasfasern gebildet. Die Herstellung einer solchen neuerungsgemäßen Bandage ist einfacher und billiger als eine reine Glasfaserbandage. Andererseits genügt die neuerungsgemäße Bandage den Anforderungen bei elektrischen Maschinen mit hohen Temperaturen, denn selbst wenn die Kunststoffumhüllung schmilzt, bleibt sie doch an den Glasfasern hängen, d.h. sie platzt nicht auf und kann somit keine Störungen verursachen.The innovation creates a remedy here by the fact that the bana r-out a thermoplastic coated GO p. «= - 'ajerseele consists. The soul of a number of uncompromised ones becomes expedient Formed glass fibers. The production of such a bandage according to the invention is simpler and cheaper than one pure fiberglass bandage. On the other hand, the one in accordance with the innovation is sufficient Bandage meets the requirements of electrical machines with high temperatures, because even if the plastic coating melts, it does stick to the glass fibers, i.e. it does not burst and therefore cannot cause any malfunctions.

Die Zeichnung zeigt ein Ausführungsbeispiel der neuerungsgemäßen Bandage. Diese "besteht aus einer Seele 1, welche von einer Vielzahl einzelner Glasfasern gebildet ist, die unverflochten nebeneinander liegen. Auf diese Seele 1 ist eine Umhüllung 2 aus thermoplastischem Kunststoff fest aufgebracht.The drawing shows an embodiment of the bandage according to the innovation. This "consists of a soul 1, which of a Multiplicity of individual glass fibers is formed, which are not interwoven next to each other. On this soul 1 there is a cover 2 made of thermoplastic material.
