Flüssigkeitsgekühlte elektrische Maschine mit KäfigwicklungLiquid-cooled electrical machine with cage winding

Die vorliegende Neuerung betrifft eine flüssigkeitsgekühlte elektrische Maschine mit Käfigwicklung, deren State Kuhlkanäle zur Führung der Kühlflüssigkeit aufweisen. Euren die direkte Leiterkühlung mit Hilfe einer Flüssigkeit, wie 2.P. Wasser, kann die auftretende Strcir.wäriLe wirksam abgeführt werden, so daß die entsprechenden Wicklungen elektrisch höher belastet werden können. Dies ist gerade bei elektrischen Maschinen nit Käfigwicklungen, wie z.B. bei elektrischen Schlupfkupplungen oder Asynchronmaschinen, wichtig, bei üenen in bestimmten Betriebszuständen sehr hohe Verluste im Käfig oder auch im Eisenkörper entstehen können.The present innovation relates to a liquid-cooled electrical machine with a cage winding, the state of which has cooling channels for guiding the cooling liquid. Your direct conductor cooling with the help of a liquid such as 2.P. Water, the occurring Strcir.wäriLe can be effectively dissipated, so that the corresponding windings can be subjected to higher electrical loads. This is particularly important in electrical machines with cage windings, such as electrical slip clutches or asynchronous machines, where very high losses can occur in the cage or in the iron body in certain operating states.

PLA 67/CO31 GM Gemäß der Neuerung bestehen "bei der Käfigwicklung die KurzschluC-ringe aus Hohlprofilen und bilden jeweils einen Ringraum, der mit den Kühlkanälen der Wicklungsstäbe in Verbindung steht - Der eine Kurzschlußring dient als Sammelkanal für die Kühlflüssigkeitszuführung und der andere als Saiwielkanal für die Kühlflüssigkeitsatführung» Der konstruktive Aufbau einer Käfigwicklung ist dadurch in sinnvoller Weise für die Ausbildung des Kühlflüssigkeitskreislaufes ausgenutzt, indem die Kurzschlußringe die Verteilung der Kühlflüssigkeit auf die mit Kühlkanälen versehenen Wicklungestäbe übernehmen.PLA 67 / CO31 GM According to the innovation, there are "short-circuit rings" in the cage winding made of hollow profiles and each form an annular space that is connected to the cooling channels of the winding bars - the one The short-circuit ring serves as a collecting channel for the coolant supply and the other as a Saiwiel channel for the cooling liquid sate guide » The structural design of a cage winding is thereby in a meaningful way for the formation of the coolant circuit exploited by the short-circuit rings the distribution of the cooling liquid on the winding bars provided with cooling channels take over.

Es ist zweckmäßig, daß die Wicklungsstäbe mit dem sie umgebenden Eisenkörper in innigem Kontakt stehen, damit auch,die im Eisenkörper entstehenden Verluste infolge der guten metallischen Wärmeleitung zu den Wicklungsstäben von der Kühlflüssigkeit abgeführt werden können. Gegebenenfalls können zusätzliche Kühlkanäle im Eisenkörper vorgesehen sein.It is useful that the winding bars with the surrounding them Iron bodies are in intimate contact, including those in the iron body Any losses resulting from the good metallic heat conduction to the winding bars are carried away by the coolant can be. If necessary, additional cooling channels can be provided in the iron body.

Die Wicklungsstäbe 3 sind in die Bohrungen 7 im Eisenkörper 8 eingepreßt, so daß ein guter thermischer Kontakt zwischen dem Eisenkörper 8 und den Wicklungsstäben 3 entsteht. Auf diese Weise wird ein guter Wärmeübergang geschaffen, so daß auch ein Teil der im Eisenkörper 8 auftretenden Verluste durch das in den Kühlkanälen 5 fließende Kühlwasser abgeführt werden kann.The winding bars 3 are inserted into the bores 7 in the iron body 8 pressed in so that there is good thermal contact between the iron body 8 and the winding bars 3.
