Classification: CPC H  B | IPC B  H

Claim 0:
1. A rotor (1) for an electric machine (2), comprising:
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);
a nanogenerator (6) configured for generating electrical energy from at least one surroundings variable and supplying the at least one sensor element (3) and the signal processing unit (4) with the electrical energy, the nanogenerator (6) arranged on an end face of the rotor (1); and
a cooling ring (7) arranged on the end face of the rotor (1), wherein the cooling ring (7) at least partially or completely covers the nanogenerator (6), and an outer surface of the cooling ring (7) that faces away from the rotor (1) is larger than an outer surface of the nanogenerator (6) that faces away from the rotor (1).
