Abstract
A rotor () for an electric machine () operated with a pulsed voltage, the rotor () having at least one sensor element () for detecting at least one condition variable of the rotor (), and a signal processing unit () connected to the at least one sensor element (), the signal processing unit () generating measured data based on the at least one condition variable of the rotor () and transmitting the measured data to a control device (). The rotor () further having at least one induction coil () at least indirectly supported on an end face of the rotor (), the at least one induction coil () being tuned to a modulation of a fundamental wave field of a magnetic front stray field () formed during operation of the electric machine () with pulsed voltage to generate electrical energy from the fundamental wave field.
