ABSTRACT:
A method for reducing effects of torque fluctuations on a system driven by an electric motor and producing cyclically occurring, rotational speed-dependent load-torque fluctuations includes counteracting changes in load torque by effecting oppositely directed changes in drive torque so as to maintain the load torque at an approximately constant value.
