Claim 10:
11. A computer program product embodied in a non-transitory computer readable medium comprising commands which, when executed by a control unit, cause the control unit to execute a method for monitoring operation of a drive component by a coil integrated in a mobile terminal and configured for contactless charging of the mobile terminal, in particular using the Qi standard, wherein the drive component is designed as an electric rotating machine with a rotor and a stator which are accommodated in a housing of electric rotating machine, the method comprising:
capturing an electromagnetic variable of the drive component outside the housing of the electric rotating machine by the integrated coil;
measuring a flux leakage field of the stator with the integrated coil;
determining based on the captured electromagnetic variable a first frequency which comprises a stator frequency as determined from a temporal and in particular periodical change of the flux leakage field; and
determining a first status variable of the drive component from the first frequency.
