Abstract

A rotor (1) for an electric machine (2) includes at least one sensor element (3) configured for detecting condition variables 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 variables of the rotor (1) and transmitting the measured data to a control device (5), and 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 electrical energy.
