Abstract

Die Erfindung betrifft eine Anordnung mit einer Vakuumpumpe (10; 210), welche wenigstens eine Pumpstufe (12; 212) und einen die Pumpstufe antreibenden Motor (14; 214) umfasst, und mit einer Bestromungsbaugruppe (21; 221). Um den Verschleiß der Bauteile der Pumpstufe zu verringern, wird vorgeschlagen, dass die Anordnung eine Messbaugruppe (24; 224) zur Bestimmung einer elektrischen Größe aufweist. Die Erfindung betrifft außerdem ein Verfahren zum Betrieb einer Vakuumpumpe (10; 210) mit einem Motor (14; 214). Hier wird vorgeschlagen, dass die Leistungsaufnahme des Motors gemessen und bei Absinken der Leistungsaufnahme die Drehzahl des Motors gesenkt wird.

The invention relates to an arrangement comprising a vacuum pump (10, 210) comprising at least one pumping stage (12, 212) and a motor (14, 214) driving the pumping stage, and a lighting assembly (21, 221). In order to reduce the wear of the components of the pumping stage, it is proposed that the arrangement has a measuring assembly (24; 224) for determining an electrical quantity. The invention also relates to a method of operating a vacuum pump (10; 210) with a motor (14; 214). It is proposed here that the power consumption of the motor is measured and the speed of the motor is lowered when the power consumption drops.
