Description
Verfahren zur Herstellung der umhüllenden Isolation von Erregerspulen für elektrische Maschinen Es ist bekannt, daß Erregerspulen für elektrische Maschinen nach Herausnahme aus der Wickelschablone eine umhüllende Bandisolierung erhalten und nach der Verformung, die dem Joch der Maschine entspricht, imprägniert werden.Process for the production of the enveloping insulation of excitation coils for electrical machines It is known that excitation coils for electrical machines after removing it from the winding template, an enveloping tape insulation is obtained and impregnated after the deformation corresponding to the yoke of the machine.
Es ist auch bekannt, die Isolierung der Erregerspulen derart durchzuführen, daß die Spulen mit zweckmäßig geformten Stücken von Isolierstoffen umhüllt werden. Zu diesem Zwecke wird aus dem verwendeten Isolierstoff ein Stück von der Form der zu isolierenden Spule ausgeschnitten und sowohl im Inneren als auch am äußeren Rande derart ausgeschnitten, daß an diesen Stellen T-förmige Streifen entstehen. Die inneren Streifen dienen zur Isolierung der inneren Spulenteile, während die äußeren Streifen dazu verwendet «-erden, diel Spule in das Stück des Isolierstoffes einzuwickeln und die äußeren Spulenseiten dadurch zu isolieren.It is also known to isolate the excitation coils in such a way that that the coils are encased with appropriately shaped pieces of insulating material. For this purpose, a piece of the shape of the insulating material is used Cut out coil to be insulated and both inside and on the outer edge cut out in such a way that T-shaped stripes are formed at these points. The inner ones Strips are used to isolate the inner coil parts, while the outer strips used to wrap the coil in the piece of insulating material and thereby isolating the outer coil sides.
Solche und ähnliche Verfahren sind in Jedem Falle zeitraubend und führen oft zur ungewollten Verformung der Spulen.Such and similar procedures are time consuming and in any case often lead to unwanted deformation of the coils.
Der Erfindung gemäß wird zur Vermeidung dieser Nachteile die Spule in -eine Textilstoffhülle eingenäht. Dies geschieht zweckmäßig so, daß eine aus zwei Stücken um die Polkernöffnung zusammengenähte und gewendete Hülle in eine Wickelschablone gelegt wird, in die die Spule hineingewickelt wird. Nach Fertigstellung der Spule werden die überstehenden Teile der Hülle zugeschnitten und um die Spule vernäht. Selbstverständlich kann auch die bereits fertige Spule so mit Stoff benäht «erden, daß sie in gleicher Weise in einem ringförmigen Beutel eingeschlossen ist.According to the invention, in order to avoid these disadvantages, the coil sewn into a textile cover. This is done expediently so that one out Two pieces of sleeve sewn together around the pole core opening and turned inside out in a winding template into which the bobbin is wound. After completing the coil the protruding parts of the cover are cut and sewn around the spool. Of course, the already finished spool can also be sewn with fabric so that it can be earthed. that it is likewise enclosed in an annular bag.
Die nach dem erfindungsgemäßen Verfahren hergestellten Spulen werden zweckmäßig in an sich bekannter Weise zur Erhöhung des Isolationswiderstandes mit Isolierfolien umlegt.The coils produced by the method according to the invention are expediently in a manner known per se to increase the insulation resistance Foil wraps around.
Die Zeichnung zeigt beispielsweise eine Spule und die Mittel zur Herstellung einer Hülle.The drawing shows, for example, a coil and the means for producing it a shell.
Abb. i zeigt die Stoffteile der Hülle. Abb. 2 zeigt die Teile im Schnitt. Abb.3 zeigt eine Wickelvorrichtung. Abb. 4. zeigt die fertige Spule in Draufsicht. Abb. 5 zeigt die Spule in Ansicht.Fig. I shows the fabric parts of the cover. Fig. 2 shows the parts in section. Fig.3 shows a winding device. Fig. 4. shows the finished coil in plan view. Fig. 5 shows the coil in perspective.
Abb. 6 zeigt die Spule im Schnitt.Fig. 6 shows the coil in section.
Zwei rechteckige Stoffteile i, 2 werden um die Polkernöffnung 3 zusammengenäht, gewendet und in die in Abb.3 dargestellte Wickelvorrichtung eingelegt, die aus einem zu drehenden Körper .1 mit einer durch eine Schraube 5 befestigten Deckplatte 6 besteht. Zusätzliche durch Schrauben 7 gehaltene Platten 8 bilden mit den anliegenden Wickelvorrichtungsteilen Nuten, in denen. die Hüllenblätter i, 2 durch Spiralfedern 9 o. dgl. während des Wickelns festgehalten werden. Nach Wicklung der Spule werden die überstehenden Hüllenränder gelöst, beschnitten und über der Spule nach Falzung zusammengenäht. Die fertig eingehüllte Spule ist nach Lösung der Deckplatte aus der Wickelvorrichtung zu entnehmen.Two rectangular pieces of fabric i, 2 are sewn together around the pole core opening 3, turned and inserted into the winding device shown in Figure 3, which consists of a body to be rotated .1 with a cover plate 6 fastened by a screw 5 consists. Additional plates 8 held by screws 7 form with the adjacent ones Winder parts grooves in which. the hull leaves i, 2 by spiral springs 9 or the like. Be held during winding. After winding the coil will be the protruding envelope edges loosened, trimmed and folded over the spool sewn together. The finished wrapped coil is off after the cover plate has been removed to be taken from the winding device.
