On the issue of energy consumption of vibration technological machines

Abstract

Abstract The article provides a comparative analysis of the energy consumption required for the implementation of the resonant and beyond-resonant modes of vibrating technological machines working body’s oscillations. An algorithm for selecting parameters of an electric drive based on an asynchronous electric engine to provide the specified amplitude and frequency of the working body oscillations for both modes of vibration is presented, taking into account frequency regulation, losses arising in the elastic suspension of the machine and in bearings of engine, the occurrence of reactive power and changes in the energy conversion efficiency.
