Description

Elektrische Kleinmaschine, deren Ständerbleche auf einen geschlossenen Rahmen aus elektrisch leitendem material aufgeschoben sind. Es ist bekannt, den Rahmen von Kleinmotoren für Wechselstrom zur Unterbindung der auftretenden Wirbelströme zu unterteilen. Aus fabrikationstechnischen Gründen sowie im Hinblick auf die Festigkeit des Rahmens ist es aber -erwünscht, daß er ein geschlossenes Ganzes bildet. Das der Erfindung zugrunde liegende Verfahren ermöglicht es nun, den Rahmen so zu gestalten, daß die "vVirbelstrombildung in ihm vermindert und er doch völlig geschlossen und steif ist, Abb. r zeigt den Rahmen von der Stirnseite und Abb.2 in der Seitenansicht. Die Abb. 3 und q. stellen den eingesetzten Isolierttäger dar.Small electric machine, the stator plates on a closed Frames made of electrically conductive material are pushed on. It is known the Frame of small motors for alternating current to prevent the eddy currents that occur to subdivide. For manufacturing reasons as well as with regard to strength of the framework, however, it is desirable that it form a coherent whole. That The method on which the invention is based now makes it possible to design the frame in such a way that that the eddy current formation in him is reduced and yet he is completely closed and is stiff, Fig.r shows the frame from the front and Fig.2 in the side view. Fig. 3 and q. represent the insulated carrier used.

Ein aus Steatit oder anderem Isoliermaterial gleicher Festigkeit und Feuerbeständigkeit bestehender Körper c von der in Abb. 3 und q. wiedergegebenen Form wird in die. Spritzgußform eingelegt und mit eingegossen. Durch die durch den Schlitz a unterbrochenen schwalbenschwanzförmigen Erweiterungen b wird der Rahmen nach jeder Richtung, hin versteift, und die eigenartige Form des Isolierstückes c verhindert ein Verziehen oder Verschieben des Rahmens während der Fabrikation und im Betrieb. Außerdem sind die Wirbelströme durch die isolierende Wirkung des Isolierkörpers unterbunden.One made of steatite or other insulating material of the same strength and Fire resistance of existing bodies c from that in Fig. 3 and q. reproduced Shape will be in the. Injection mold inserted and poured in. Through the through the Slot a interrupted dovetail extensions b becomes the frame stiffened in every direction, and the peculiar shape of the insulating piece c prevents the frame from warping or shifting during manufacture and in operation. In addition, the eddy currents are due to the insulating effect of the Isolating body prevented.

PATENTANSPRUCH: Elektrische Kleinmaschine, deren Ständerbleche auf einen geschlossenen Rahmen aus elektrisch leitendem Material aufgeschoben sind, dadurch gekennzeichnet, daß das leitende Material des Rahmens an. einer Stelle durch einen Schlitz unterbrochen ist, der durch ein eingeschlossenes Isolierstück (c) solcher Form wieder geschlossen ist, daß es die beiden Rahmenenden allseitig fest zusammenhält, zum Zweck, die Ausbildung schädlicher Ströme im Rahmen zu verhindern. PATENT CLAIM: Small electrical machine whose stator plates are pushed onto a closed frame made of electrically conductive material, characterized in that the conductive material of the frame is attached to. one point is interrupted by a slot which is closed again by an enclosed insulating piece (c) of such a shape that it holds the two frame ends firmly together on all sides, for the purpose of preventing the formation of harmful currents in the frame.
