VACUUM PUMP
First Claim
1. A vacuum pump comprising a pump rotor and a pump stator, the pump rotor including a transponder with a rotor antenna and the pump stator including a reader with a stator antenna and at least one sensor for the detection of wear-relevant operating data,wherein the pump rotor comprises a memory that stores operating data or a service life characteristic calculated on the basis of the operating data and reads the same out to the reader via the transponder.

Abstract
A pump rotor (11) contains a transponder (14) that can be read out by a reader (12) of a pump stator (10). The pump rotor (11) also contains sensors (26) for determining operating data (BD), and a memory (27). The memory (27) stores either the history of the measured operating data (BD) or a service life characteristic (LDK). In this way, the rate of wear of the respective rotor is determined and stored in the rotor, and the rotor therefore contains all of the information relating to maintenance. The rotor-related information remains in the rotor even if the rotor is used in another vacuum pump.
