Abstract

As the conducted studies show, deviations and asymmetry of the outside 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 their productivity decreases with voltage asymmetry. However, there are no studies on the influence of spring asymmetry on the energy characteristics of working machines. The purpose of the research is to determine the influence of voltage asymmetry on the energy characteristics of milk separators. With voltage asymmetry, constant and variable losses in an asynchronous electric motor change. It is proposed to carry out an energy assessment of the milk separator based on the specific power consumption. The influence of voltage asymmetry on the energy characteristics of milk separators was studied. 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 increase with voltage asymmetry. As a result, specific power losses in milk separators increase.

电压不对称对通风装置能量特性的影响

正如所进行的研究表明，外部的偏差和不对称对生产机器和机构的电力驱动影响最大。电压不对称会导致电磁和技术方面的损失。电压不对称对工作机器和机构技术特性影响的研究表明，它们的生产率随着电压不对称而降低。然而，关于弹簧不对称对工作机械能量特性影响的研究尚未见报道。研究的目的是确定电压不对称对牛奶分离器能量特性的影响。由于电压不对称，异步电动机的恒损和变损都会发生变化。建议基于比功耗对牛奶分离器进行能量评估。研究了电压不对称对牛奶分离器能量特性的影响。得到了比功耗与电压不对称引起的电机机械特性刚度变化的依赖关系。结果表明，滑移和功率损耗随电压不对称而增大。因此，牛奶分离器的功率损失增加了。
