Description

'-luftstrom eingeengt, damit nach dem Ejektorpritizip Luft aus dem anderen Stirnraum 14 angesaugt wird. In diesen Stirnrahm tritt durch jalousieartig abgedeckte Öffnungen 15 Kühlluft ein und strömt zwischen' den Wickelköpfen 16 hindurch. Stattdessen kann in den Stirnraum 14 auch durch -Kanäle 17 im Läufer 18 Kühlluft von den Offnungen 7 her eingesaugt werden. Airflow is restricted so that air is sucked in from the other end space 14 after the ejector principle. Cooling air enters this end frame through openings 15 which are covered in the manner of louvers and flows between the end windings 16. Instead, cooling air can also be sucked into the end space 14 through channels 17 in the rotor 18 from the openings 7.

Fig.2 zeigt eine andere Ausführungsform der Erfindung, und zwar einen NLotor mit fliegend angeordnetem Läufer 18o, bei denn die lreid:n Motorlager 19, 2o auf der gleichen Stirnseite angeordnet sind. Das eine Lager 20 springt so weit in den Stirnraum vor, daß dort kein Lüfter angebracht werden kann. Im übrigen ist die Anordnung die gleiche wie bei Fig. t. Für entsprechende Teile sind gleiche Bezugszeichen verwendet. Natürlich kann in den .Stirnraum 14 (Fig. 2) statt durch jalousieartig abgedeckte Öffnungen 15 auch durch entsprechende Kanäle von unten her Kühlluft eingesaugt werden.Fig.2 shows another embodiment of the invention, namely one N motor with overhung rotor 18o, because the lreid: n motor bearings 19, 2o are arranged on the same face. One bearing 20 jumps so far in the front space so that no fan can be attached there. Otherwise is the arrangement is the same as in Fig. t. The same reference symbols are used for corresponding parts used. Of course, in the. Front space 14 (Fig. 2) instead of blind-like covered openings 15 also sucked in cooling air from below through corresponding channels will.

Die Artordnung nach der Erfindung bietet den XO'rteil, daß auch der Stirnraum, in dein nicht geniigend Platz zur Unterbringung eines Lüfters ist, mit frischer Kühlluft durchspült wird.The species order according to the invention offers the advantage that also the Forehead space in which there is not enough space to accommodate a fan fresh cooling air is flushed through.
