Abstract
Ein Elektromotor weist einen Rotor und einen Stator auf. Es ist eine Kühleinrichtung vorgesehen, welche zur Kühlung des Stators ausgebildet ist. Die Kühleinrichtung weist einen von einem Kühlmedium durchströmbaren Kühlkanal auf, welcher mit einem Vergußmaterial vergossen und wenigstens abschnittsweise auf der Oberfläche des Stators angeordnet ist.An electric motor has a rotor and a stator. A cooling device is provided, which is designed to cool the stator. The cooling device has a cooling channel through which a cooling medium can flow, which is encapsulated with a potting material and arranged at least in sections on the surface of the stator.
Description
Die Erfindung betrifft einen Elektromotor nach dem Oberbegriff des Anspruchs 1.The The invention relates to an electric motor according to the preamble of the claim 1.
Entsprechende
Motoren weisen eine Kühleinrichtung auf, mit der der Motor
im Betrieb gekühlt wird. Aus
Aufgabe der Erfindung ist es daher, einen Elektromotor der eingangs genannten Art anzugeben, dessen Kühlung effektiver ist und bei welchem die geschilderten Nachteile nicht auftreten.task The invention is therefore an electric motor of the aforementioned Specify type whose cooling is more effective and in which the described disadvantages do not occur.
Gelöst wird diese Aufgabe durch einen Elektromotor mit den Merkmalen der Ansprüche 1 und 4. Vorteilhafte Ausführungsformen finden sich in den Unteransprüchen.Solved This task is accomplished by an electric motor with the characteristics of Claims 1 and 4. Advantageous embodiments can be found in the subclaims.
Erfindungsgemäß sind die Kühlkanäle aus einem wendelförmigen oder mäanderförmigen Rohr gebildet, welches entweder zusammen mit einem wärmeleitfähigen Vergußmaterial oder aber direkt auf dem Stator aufgebracht ist.According to the invention the cooling channels of a helical or meandering tube is formed, which either together with a thermally conductive potting material or is applied directly on the stator.
Im ersten Fall wird durch den Verguß ein nahezu perfekter thermischer Kontakt zwischen Stator und Kühlkanal hergestellt. Im zweiten Fall, der sich besonders bei einer annähernd runden Außenkontur des Stators eignet, ist das wendelförmige Rohr bevorzugt mit rechteckigem Querschnitt ausgebildet und die aus einem hinreichend flexiblen Material gebildete Wendel weist einen etwas kleineren Durchmesser auf als der Stator, so daß die Wendel gespreizt auf den Stator aufgeschoben werden kann und sich nach dem Aufschieben elastisch zusammenzieht und am Stator satt, d. h. weitestgehend ohne Zwischenraum, anliegt.in the The first case becomes almost perfect by casting thermal contact between stator and cooling channel produced. In the second case, especially at an approximate round outer contour of the stator is the helical Pipe preferably formed with a rectangular cross-section and the from a sufficiently flexible material formed helix has a slightly smaller diameter than the stator, so that the Spiral spread on the stator and can be pushed contracts elastically after pushing on and is full on the stator, d. H. largely without space, is present.
