Kühlanordnung für geschlosse-ne elektrische Maschinen mit ge. hlt@m Standergehause Bs sind Kühlanordnungen für elektrische Maschinen bekanntge- r <uBstram worden bei denen der Kühllnftstrom der durch wei an den Enden der Maschine angeordnete Lüfter erzeugt wird, inner- halbder ganz geschlossenen lagerschilde verläuft und die in den Wiekelk5pfen aufgenommene ;/ärme an die im Ständer- gehl : aserücken angebrachte Luft-oder Wasserkühlung abgibt.

Da der KShIInftstrQm durch di Stirnseiten der Jasohinegeführt ist, entfallen die Lttftdurchtrittsöftnungaa im Gehäusemantel, wodurch eine gröBere Steifheit des Stân- derehSgs erreicht wird Bei einer elektrischen Maschine ohne Drehrichtungsumkehr wird zur Erzeugung des Kühlluftstromee mir ein AxiallSftey verwendet,was zu einer weiteren Verkürzung den lagerab- standes führt. Der durch oder fiber das Ständerbleahpaket geleitete Kühl- luftatrom führt hauptsächlich die Verlustwärme aus den ikelk8pfen ab, während die Verlu-etwärme des Blechpaketes und der in diese eingelegten Wieklang durch direkte Lei- tung an den gekühlten Innenmantel. des Gehäuses abgegeben wird, Ein Aasführungsbeispiel nach der Nenerung wird snbnd der Fig. 1 und 2 erläuterts, Fig. 1 stellt den längssehnitt und Fig. 2 die 3eitenansioht einer elektrischen Maschine dar.

Since the KShIInftstrQm through the front sides of the Jasohine is led, the Lttftdurchtrittsöftnungaa are omitted in the casing, which increases the rigidity of the derehSgs is achieved In the case of an electrical machine without reversing the direction of rotation an AxiallSftey is used to generate the cooling air flow used, which leads to a further shortening of the state leads.
