Abstract
Disclosed is a method for monitoring the operation of a drive component. In order to minimize additional hardware complexity, the monitoring method is cared out by a coil that is integrated in a mobile terminal by acquiring an electromagnetic variable of the drive component outside a housing of the drive component by the integrated coil, determining at least one first frequency based on the acquired electromagnetic variable, and determining a first status variable of the drive component from the at least one first frequency.
