Description
Die Erfindung betrifft einen magnetisierbaren Nutenverschlußkeil für elektrische Maschinen mit gleichsinnig zur Maschinenlarnellierung: ver- ■ laufenden Blechlamellen, die nach, außen offene, in axialer Richtung verlaufende Aussparungen haben. Die bekannten' lameliierten Nutenverschlußkeile sind entweder nach ihrem Aufbau bzw. hinsichtlich ihrer Handhabung beim Einsetzen und Ausbauen sehr umständlich oderThe invention relates to a magnetizable slot wedge for electrical machines with in the same direction as machine tilting: ver ■ running sheet metal lamellas that are open to the outside, have recesses running in the axial direction. The well-known 'laminated slot wedges are either very awkward or cumbersome in terms of their construction or in terms of their handling when inserting and removing
ίο sie tragen den Bedürfnissen = der.. Eraxis„ nach, festem Sitz in der Nut und Beseitigung aller durch sie entstehenden störenden "Einflüsse in magnetischer und elektrischer Beziehung" nur unvollkommen oder gar nicht Rechnung.ίο they carry the needs = of the .. Eraxis "after, tight fit in the groove and elimination of all disturbing "influences caused by it magnetic and electrical relationship "only imperfect or no account at all.
Zweck der Erfindung ist nun, einen Nutenverschlußkeil aus lameliierten Blechen "zu" schaffen, der geringe zusätzliche Verluste und andererseits eine solche mechanische Festigkeit aufweist, daß eine Lockerung der einzelnen Eisenkörper in der Nut nicht zu befürchten ist. Erreicht wird dieser Zweck dadurch, daß die Blechlamellen durch eine in den Aussparungen liegende Schleife aus nicht magnetisierbarem, metallischem Werkstoff zusammengehalten sind, deren Enden entweder elektrisch voneinander getrennt oder zur Bildung der bei Nutenverschlüssen bekannten Kurzschlußwicklung miteinander verbunden sind.The purpose of the invention is now to "to" a slot wedge made of laminated metal sheets create the low additional losses and on the other hand such mechanical strength has that a loosening of the individual iron bodies in the groove is not to be feared is. This purpose is achieved in that the sheet metal lamellae through one in the recesses lying loop made of non-magnetizable, metallic material held together are, the ends of which are either electrically separated from each other or to form the at Slot closures known short-circuit winding are connected to one another.
In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung in perspektivischer Ansicht und im Querschnitt dargestellt, ι sind die den Nutenkeil bildenden Lamellen, welch§ in Längsrichtung des Keiles verlaufende Aussparungen.2 und 3 besitzen. In diese Aus-' sparungen ist eine Schleife 4 aus nicht magneti- -35 sierbarem, metallischem Werkstoff eingebaut, weiche -.den. Zusammenhalt .der Lamellen 1 bewirkt und deren Enden entweder elektrisch voneinander getrennt oder zur Bildung der bei Nutenverschlüssen bekannten Kurzschlußwicklung miteinander verbunden sind. Diese Schleife 4 ist zweckmäßig ,gegenüber den Lamellen durch eine Zwischenlage 5 aus Isolierstoff isoliert. Beim Schließen,-der·.Schleife 4 wirkt diese in bekannter "Weise" "wie "eine kurzgeschlossene Windung, welche den Kraftlinienfluß durch den Steg 6 der Keillamellen erheblich vermindert. Das .hat eine Verminderung der Streuung im Gefolge.In the drawing, an embodiment of the object of the invention is shown in perspective view and in cross section, ι are the slats forming the groove wedge, which extend in the longitudinal direction of the wedge Have recesses 2 and 3. In this aus' savings, a loop 4 made of non-magnetizable metallic material is built in, soft -.den. Cohesion .the slats 1 causes and their ends either electrically separated from one another or to form the at Slot closures known short-circuit winding are connected to one another. This loop 4 is useful across from the slats an intermediate layer 5 insulated from insulating material. When closing the loop 4, it acts in known "way" "like" a short-circuited turn, which the flux of force lines through the web 6 of the wedge lamellae is significantly reduced. That has a reduction in the spread in the wake.
