Saving electrical energy by using induction motors with pole changing windings in the water supply system

Abstract

This article provides information on the level of provision of clean drinking water to the population of Republic of Uzbekistan and the work carried out in the field, as well as the deficiencies that arise in the water supply enterprise and measures to eliminate them. The operation modes of the enterprise’s pump units, the analysis of the main parameters and the possibility of saving electricity and water consumption due to the application of two-speed asynchronous motors with pole change winding for such equipment are presented.
