Algorithmization of control processes of a hoisting unit induction motor with adjustable resistances in the rotor

Abstract

Abstract The induction electric drive with a rotary station, despite its shortcomings, is still widely used for existing lifting installations. One of the ways to modernize these electric drives is the transition to a digital control system. The article presents a mathematical model of an induction motor when regulating resistances in the rotor circuit. A mathematical model of a logical control system is proposed and an algorithmic structure of a digital logical control system is drawn up, which allows problems of implementing these control systems to be solved.
