Description
Luftgekühlter Elektromotor der Durchzugstype mit schleifenfgrmiger Luftführung nach Patent 381609. Wird bei Maschinen, die nach Patent 38i6og ausgeführt sind, eine absolute Staubfreiheit im Wickelungsraum verlangt, so sind gemäß der vorliegenden Erfindung zur Erreichung dieses Zweckes folgende Anordnungen zu treffen: Dort, wo die Luftschleife für den Innenraum vom Hauptluftstrom abzweigt, wird eine Zwischenwand J eingefügt. In diese Zwischenwand wird ein Luftfilter K eingebaut, der aus Gründen der Raumersparnis z. B. als sogenannter Prallflächenfilter ausgeführt sein kann. Der Filter wird in diese Zwischenwand durch eine Klappe am Lagerschild eingeführt.Air-cooled electric motor of the pull-through type with loop-shaped air duct according to patent 381609. If machines that are designed according to patent 38i6og require absolute freedom from dust in the winding room, the following arrangements must be made according to the present invention to achieve this purpose: Where the air loop for branches off the interior from the main air flow, a partition J is inserted. In this partition, an air filter K is installed, the z. B. can be designed as a so-called baffle filter. The filter is inserted into this partition through a flap on the end shield.
