Abstract
As the conducted studies show, deviations and voltage asymmetry have the greatest impact on the electric drives of production machines and mechanisms. Voltage asymmetry leads to losses that have an electromagnetic and technological component. Studies on the effect of voltage asymmetry on the technological characteristics of working machines and mechanisms have shown that with voltage asymmetry, the angular speed of the motor decreases, which will lead to a decrease in their productivity. However, there are no studies on the influence of voltage asymmetry on the energy characteristics of crushers. The purpose of the research is to determine the influence of voltage asymmetry on the energy characteristics of crushers. With voltage asymmetry, constant and variable losses in an asynchronous electric motor change. It is proposed to carry out an energy assessment of crushers based on the specific consumption of electricity. The influence of voltage asymmetry on the energy characteristics of crushers was studied. The dependence of the specific power consumption on the change in stiffness of the mechanical characteristics of the electric motor, which is due to voltage asymmetry, is obtained. It was established that slippage and power losses increase with voltage asymmetry. As a result, the specific consumption of electricity in crushers increases.
