Abstract

Deviations and asymmetry of the surface 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.

The effect of voltage asymmetry on the technological characteristics of working machines and mechanisms is manifested in a decrease in their productivity. However, there are no studies on the influence of voltage asymmetry on the energy characteristics of working machines.

The purpose of the research is to establish the influence of voltage asymmetry on the energy characteristics of nori.

Voltage asymmetry leads to a change in constant and variable losses in an asynchronous electric motor.

It is proposed to carry out an energy assessment of the electric drive of the nori according to the specific consumption of electricity.

A study of the effect of voltage asymmetry on the energy characteristics of the electric drive of the noriy was carried out. The dependence of the specific power consumption on the change in stiffness of the mechanical characteristics of the electric motor, which is caused by voltage asymmetry, is obtained. It was established that slippage and power losses in an asynchronous electric motor increase with voltage asymmetry. As a result, the specific losses of electricity in the norias increase.

Key words: noria, voltage asymmetry, power, noria productivity, specific electricity consumption
