Description

Geschlossener Induktionsmotor, bei dem die Kühlluft durch am Gehäuseumfang angeordnete und mit Reinigungsöffnungen versehene Kanäle getrieben wird Neuerdings werden vielfach ganz geschlossene Elektromotoren mit einer Einrichtung zum Kühlen des Mantels versehen. Solche Motoren besitzen in der Regel einen Mantel mit Kanälen, durch die mittels eines Gebläses Kühlluft geblasen wird, welche die im Motor erzeugte Wärme abführt. Diese Kühlkanäle füllen sich im Laufe der Zeit mehr oder weniger, je nach dem Grad der Reinheit der Kühlluft, mit Staub an, so daß, sie von Zeit zu Zeit gereinigt werden müssen. Zu diesem Zweck werden verschließbare Klappen o. dgl. angeordnet, die beim Reinigen der Kanäle zu öffnen sind, um danach wieder geschlossen zu werden. Diese Klappen sind natürlich umständlich und lästig. Sie sollen deshalb der vorliegenden Erfindung gemäß. ganz vermieden werden.Closed induction motor in which the cooling air passes through the housing arranged and provided with cleaning openings channels is driven recently are often completely closed electric motors with a device for cooling of the coat. Such motors usually have a jacket with channels, through which the cooling air generated in the engine is blown by means of a fan Dissipates heat. These cooling channels fill up more or less over time, Depending on the degree of purity of the cooling air, with dust on, so that, from time to time Time to be cleaned. For this purpose, closable flaps o. The like. arranged, which are to be opened when cleaning the channels, to then closed again to become. These flaps are of course cumbersome and annoying. You should therefore according to the present invention. be avoided entirely.

Die Erfindung besteht darin, daß in der Richtung des Luftstromes injektorartig wirkende Öffnungen an den Kanälen vorgesehen sind, und zwar derart, daß je eine öffnung in Richtung des Kanals. liegt.The invention consists in that in the direction of the air flow like an injector acting openings are provided on the channels, in such a way that each one opening towards the canal. lies.

Hierdurch wird erreicht, daß ein Aus: treten der Kühlluft durch diese öffnungen während des Betriebes nicht möglich ist. Im Gegenteil wird durch die Öffnungen sogar noch von außen Luft mit angesaugt, die die Kühlkanäle mit durchströmt.This ensures that an exit: the cooling air passes through them opening is not possible during operation. On the contrary, through the openings Air is even drawn in from the outside, which flows through the cooling ducts.

In der Zeichnung ist ein solcher Motor in Stirnansicht und Längsschnitt dargestellt. Das auf der Motorwelle sitzende GebläseB saugt durch die öffnung A des Lagerschildes die Kühlluft an und treibt sie durch die Kanäle C des Gehäuses, so daß sie an der gegenüberliegenden Seite wieder austritt.In the drawing, such a motor is in front view and longitudinal section shown. The fan B on the motor shaft sucks through opening A. the end shield and the cooling air drives it through the channels C of the housing, so that it exits on the opposite side.

Die Reinigungsöffnungen sind mit D bezeichnet und liegen je vor einem Windkanal C. Durch diese öffnungen D lassen sich die Windkanäle leicht mit einer Bürste oder auch durch einen Schlauch mit Preßluft reinigen. Besondere Frischluftklappen sind nicht erforderlich, da die Öffnungen D injektorartig in den Luftstrom hineinragen, so daß nicht nur keine Luft an den Öffnungen austreten kann, sondern sogar noch Frischluft von außen mit angesaugt wird.The cleaning openings are labeled D and are each in front of one Wind tunnel C. Through these openings D, the wind tunnels can easily be opened with a Clean the brush or through a hose with compressed air. Special fresh air flaps are not required, as the openings D protrude into the air flow like an injector, so that not only can no air escape from the openings, but even more Fresh air is drawn in from the outside.

Die Erfindung ermöglicht eine Reinigung der Kühlkanäle auch während des Betriebes.The invention enables the cooling channels to be cleaned even during of the company.
