Abstract

Die Erfindung betrifft eine Vakuumpumpe zur Erzeugung von Grob- oder Feinvakuum mit Motor, mit Steuerelektronik, mit Gaseinlass und Gasauslass, Pumpsystem und Gehäuse. Um bei einem günstigen Kostenrahmen den Wärmehaushalt zu verbessern, wird vorgeschlagen, dass das Gehäuse wenigstens zwei Abschnitte aufweist, von denen ein Steuerungsabschnitt die Steuerelektronik und ein Pumpabschnitt das Pumpsystem beinhaltet.

Figure imgaf001
The invention relates to a vacuum pump for generating coarse or fine vacuum with motor, with control electronics, with gas inlet and gas outlet, pumping system and housing. In order to improve the heat balance at a favorable cost, it is proposed that the housing has at least two sections, of which a control section includes the control electronics and a pump section the pumping system.
