Claim 13:
14. A device for monitoring operation of a drive component designed as an electric rotating machine with a rotor and a stator which are accommodated in a housing, the device comprising:
a mobile terminal;
a coil integrated in the mobile terminal and configured for contactless charging of the mobile terminal, in particular using the Qi standard, said coil configured to capture an electromagnetic variable of the drive component outside the housing of the drive component and to capture a temporal change of a flux leakage field of the electric rotating machine; and
an evaluation unit configured to determine a first frequency, which comprises a stator frequency, based on the captured electromagnetic variable and to determine a first status variable of the drive component from the first frequency.
