Description
Die Erfindung. betrifft eine Nutensolation fürelektrische-Maschinen. Ein -wesentlicher Nachteil der bekannten Nutenisolationen für elektrische Maschinen liegt darin, daß namentlich an den Nutenausgängen ein verhältnismäßig hoher Verschleiß auftritt. An diesen Stellen nämlich werden die elektrischen Wicklungen leicht schadhaft.The invention. relates to a slot insulation for electrical machines. A major disadvantage of the known slot insulation for electrical machines lies in the fact that there is a relatively high level of wear, particularly at the groove exits occurs. The electrical windings are easily damaged at these points.
Gemäß der vorliegenden Erfindung wird diesem Übelstand dadurch begegnet, daß man die stirnseitig vorgesehenen Isolationsendscheiben im Gebiet der Nuten auflappt und die Lappen derart umbiegt, daß sie eine Stütze und/oder einen Schutz für die Wickelköpfe bilden.According to the present invention, this drawback is countered by that the insulation end disks provided on the end face are opened in the area of the grooves and bends the tabs so that they provide support and / or protection for the Form winding heads.
In der Zeichnung sind einige Ausführungsbeispiele dargestellt.Some exemplary embodiments are shown in the drawing.
Fig. i zeigt eine Isolationsscheibe-vön -vorn, Fig.2 einen Teil eines Längsschnittes durch einen Läufer einer elektrischen Maschine; und die -Fig. 3 bis 5 zeigen andere Ausführungsformen. Die Isolationsendscheibe i ist, wie aus Fig. i ersichtlich, mit Schlitzen 2 und 3 versehen, durch welche die Nutenlappen 4 aus der Isolationsendscheibe gebildet werden. Der Nutenlappen.4 kann, wie aus Fig. 2 ersichtlich und bei 5 angedeutet, in Richtung auf die Achse des Läufers umgebogen und in die Druckscheibe 6 eingelegt werden. Man kann die Isolationslappen auch eine Schlaufe 7 bilden lassen, wie Fig. 3 zeigt, oder ihn in die Nut 8 selbst einlegen, so daß er, wie aus Fig. 5 ersichtlich, auf dem Nutengrund die bei 9 dargestellte Lage einnimmt.Fig. I shows an insulating disk-from-front, Fig.2 shows a part of a Longitudinal section through a rotor of an electrical machine; and the -Fig. 3 to 5 show other embodiments. As shown in Fig. i can be seen, provided with slots 2 and 3, through which the grooved tabs 4 from the isolation end disk are formed. As shown in FIG. 2 can be seen and indicated at 5, bent in the direction of the axis of the rotor and placed in the pressure disc 6. You can also use the isolation rag Let the loop 7 form, as shown in FIG. 3, or insert it into the groove 8 itself, so that, as can be seen from Fig. 5, the groove shown at 9 on the groove base Position.
Wie aus Fig: 4 ersichtlich, kann man bei Verwendung mehrerer Isolatiönsendscheiben io auch die Nutenlappen i i verdoppeln, so daB, sie den Wickelköpfen 1.2 eine besonders wirksame Stütze bieten. Die neue Nutenisolation hat den Vorteil,. daß ;das beim üblichen Stanzen der°Nüten bisher abfallende Material zur effektiven Isolierung herangezogen wird. Die neue Isolation bietet einen besonders wirksamen Schutz- gegen die meist an den Nutenausgängen auftretenden Wicklungsschäden.As can be seen from FIG. 4, when using several Isolatiönsendplatten io also double the grooved lobes i i, so that they give the winding heads 1.2 a special provide effective support. The new slot isolation has the advantage. that; that at usual punching of the ° grooves previously sloping material for effective insulation is used. The new insulation offers a particularly effective protection against the winding damage that usually occurs at the slot exits.
