FIELD: electricity.
SUBSTANCE: variable speed drive system using an electric motor and a frequency converter disposed between an AC power source and an electric motor. The frequency inverter operates in such a way as to convert the AC power received from the AC power source to the source frequency into a converted power supply with a variable drive frequency. The mechanical unit is connected to an electric motor. A scheme of electrical modulation, interacting with a frequency converter, is created. It is designed to excite oscillations of the interharmonic frequencies of the interharmonic currents generated in the frequency converter, independent of the excitation of torsional vibrations in the mechanical node and the AC power source.
EFFECT: increasing the accuracy of vibration damping and simplification.
