The study of electric drive mutual influence in the multi-motor machines

Abstract

The article describes a mathematical model of a system of two electric motors mounted on a viscoelastic base with one degree of freedom. Based on the mathematical model, a simulation model has been developed that allows us to study the dynamic behavior of unbalanced electric motors. The influence of the viscoelastic base parameters on the asynchronous motors starting time and on the amplitude of their rotor speed fluctuations is estimated. It is established that motors located on one base significantly affect each other even with a small vibrations amplitude: transient processes are delayed, high-speed low power motors are subject to overloads and destruction.
