Abstract

A rotor (1) for an electric machine (2) has a rotor body including multiple poles. The rotor (1) further has at least one sensor element (3) for detecting at least one condition variable of the rotor (1), and a signal processing unit (4) connected to the at least one sensor element (3). The signal processing unit (4) is configured to generate measured data from the condition variable of the rotor (1) and to transmit the measured data to a control device (5). Additionally, the rotor (1) has at least one induction coil (7), where each of the at least one induction coil (7) includes at least one electrical conductor (8). The at least one induction coil (7) is arranged at the rotor (1) and is configured to generate electrical energy from a magnetic field that is temporally changing during operation of the electric machine (2).
