Abstract
The present disclosure relates to a system to compensate for mechanical forces on a rotating rotor of an electric machine, to a method for compensating mechanical forces on a rotating rotor of an electric machine, and to a use of a corresponding system. Disclosed is a system for compensating torsions at a rotating rotor. The system includes at least one measuring device for measuring specific properties of the rotor, an analyzer unit for analyzing the measurement data of the measuring device, a compensation means for compensating the torsions at the rotor, the compensation means comprise a power supply unit generating a signal adapted in amplitude and frequency to the measured properties of the rotor, and to apply the generated signal to the rotor, and the power supply unit is a frequency converter.
