Influence of voltage asymmetry on the energy characteristics of feed mixers

The conducted studies have shown that deviations and asymmetry of the output have the greatest impact on the electric drives of production machines and mechanisms. Studies on the influence of voltage asymmetry on the technological characteristics of working machines and mechanisms have shown that with voltage asymmetry their productivity decreases. However, there are no studies on the influence of voltage asymmetry on the energy characteristics of working machines. The purpose of the study is to establish the influence of voltage asymmetry on the energy characteristics of feed mixers . With voltage asymmetry, constant and variable losses in an asynchronous electric motor change, which cause an increase in energy losses in an asynchronous electric drive. The energy assessment of the electric drive of feed mixers was carried out by specific electricity consumption. A study of the influence of voltage asymmetry on the energy characteristics of feed mixers was conducted. The dependence of the specific electricity consumption on the change in the rigidity of the mechanical characteristic of the electric motor, which is due to voltage asymmetry, was obtained. It has been established that with voltage asymmetry, slip and power losses increase. As a result, the specific power loss in the electric drives of feed mixers increases.
