Abstract

Abstract. The article discusses the issues of the principle of constructing an automatic control system for a multi-motor controlled electric drive with an electrical connection along the rotor chain of asyn-chronous electric motors with phase rotors and a common inverter by a driven network to control the technological process of water supply of pumping units as part of a water-lifting pumping unit. The expediency of constructing a system for automatic control of the frequency of rotation of the drive motors of a pumping unit in the form of a digital electric drive, implemented through a subordinate control system, is disclosed.
