The control of the resonant mode of a vibrating machine that is driven by an asynchronous electro motor

Abstract

This article concerns the problems of the stabilization of the resonant vibration modes of a vibrating machine that is excited by an imbalanced rotor of an asynchronous AC motor, when changing the system parameters. The system frequency control of the vibration modes based on the measurement of the phase shift between the vibrations of the working member of the vibrating machine and an exciting force is suggested. A numerical algorithm for automatic tuning of the resonant mode when changing the mass of the technological loading of a vibrating machine is proposed.
