Man hat bekanntlich zwecks Ersparnis eines Außenkühlluftstromes geschlossener elektrischer Maschinen die Oberfläche des Maschinengehäuses mit axial oder radial verlaufenden Kühlrippen versehen. Dadurch wird eine entsprechende Vergrößerung der Maschinenoberfläche erreicht, wodurch die Wärmeabgabe durch Strahlung verhältnismäßig gut wird. Es ist ferner bekannt, eine wirksame Wärmeabführung aus der Maschine dadurch zu erstreben, daß das Blechpaket und das Ständergehäuse in innige mechanische Berührung miteinander gebracht werden. Schließlich hat man bekanntlich bereits zwischen das Blechpaket gehäuseloser elektrischer Maschinen Scheiben aus gut wärmeleitendem Material geschichtet, die über den Umfang des Ständers hinausragen. Würde man jedoch diese Maßnahme bei einer elektrischen Maschine mit einem Gehäusemantel treffen, so würde dies Wärmestauungen ergeben.It is known that in order to save an outside cooling air flow, closed electrical ones are used Machine the surface of the machine housing with axially or radially Provide cooling fins. This results in a corresponding enlargement of the machine surface achieved, whereby the heat dissipation by radiation is relatively good. It is also known to be effective To strive for heat dissipation from the machine that the laminated core and the Stator housing are brought into intimate mechanical contact with one another. In the end As is well known, one already has between the laminated core of frameless electrical machines Laminated discs made of a material that conducts heat well and protrude beyond the circumference of the stand. One would, however take this measure in an electrical machine with a housing jacket, see above this would result in heat build-up. Dem Eeka: η en gegenüber w'rd die Wärmeabführung aus elektrischen Maschinen mit Gehäusemantel in folgender, an Hand derThe Eeka : η en on the other hand, the heat dissipation from electrical machines with housing jacket in the following, using the 2g Zeichnung ersichtlichen Weise noch weiter wirksam verbessert. 2 g drawing even further effectively improved as can be seen in the drawing. Der Gehäusemantel ist in bekannter Weise durch Umgießen des Ständerblechpakets 5 mit Leichtmetall hergestellt. Er besitzt in bekannter Weise axial oder radial verlaufende Kühlrippen R. Um dem Ständer die Wärme zu entziehen, besitzt der Gehäusemantel angegossene Fortsätze Ru die bis nahe an die Ständerwicklung heranreichen. Das Ständerblechpaket wird hierzu in bekannter Weise unter Freilassung von Luftschlitzen geschichtet. Beim Gießen des Gehäusemantels fließt das Gehäusemetall in diese Luftschlitze hinein und bildet nach seinem Erstarren die Fortsätze R1, die also mit dem Gehäuse zusammenhängen. Infolge des sehr weitgehenden Kontaktes zwischen dem Blechpaket und dem Gehäusemantel ergibt sich so ein äußerst guter Wärmeübergang ohne Stauung.The housing jacket is produced in a known manner by encapsulating the stator core 5 with light metal. In a known manner, it has cooling fins R running axially or radially. In order to extract the heat from the stator, the housing jacket has integrally cast projections R u which reach close to the stator winding. For this purpose, the stator core is layered in a known manner, leaving air slots free. When the housing jacket is cast, the housing metal flows into these air slots and, after it has solidified, forms the extensions R 1 , which are therefore related to the housing. As a result of the very extensive contact between the laminated core and the housing jacket, this results in extremely good heat transfer without congestion.
