Rotor for an electric machine and electric machine having a rotor

A rotor (1) for an electric machine (2) includes at least one sensor element (3) configured for detecting at least one condition variable of the rotor (1), a signal processing unit (4) connected to the at least one sensor element (3) and configured for generating measured data from the detected condition variable of the rotor (1) and transmitting the measured data to a control device (5), and at least one induction coil (7) that includes at least one electrical conductor (8), is arranged at least indirectly on an end face of the rotor (1), and is configured for generating electrical energy from a magnetic front stray field (12) rotating in relation to the rotor (1) during the operation of the electric machine (2).
