This scientific article discusses asynchronous motors using single-season and multi-season sizes, their optimized modes for scalar and vector control. First of all, detailed information was given about the operating modes of the optimizer, followed by changes in voltage, magnetic current and electric current. With scalar control, mode optimizers are optimized for maximum and minimum electric current, while with vector control, optimization is achieved through direct or indirect action on the rotor. Based on the above, complex optimization methods are considered in detail and graphs from their mathematical model are presented. In this case, the conditional minima of the electric current in the lower region and the local minima of the electric current in the lower region are shown on the graphs. The data obtained were compared with complex optimization and extraterrestrial characteristics. As a result of the article, the mentioned methods proposed a scheme of the final optimization structure and a system of equations that mathematically represent them all. The results obtained showed that even with the help of a simple circuit, optimal control of asynchronous motors can be achieved with good results when using optimizers of complex modes, rather than scalar or vector current control. In the future, the control of this method will become the basis for solving energy-saving problems achieved through the use in asynchronous motors with a short-circuited rotor, which are regulated by a frequency switch located in pumping plants of industrial enterprises.
