Improvement of reliability, energy efficiency and capacity of the hoisting and conveying equipment, i.e. conveyor systems and hoisting units, becomes a critical issue in conditions of the developing mining complex. Selection and justification of the optimal type of the electric drive and its control system are an important aspect in ensuring safe and uninterrupted operation of min ing enterprises. the article describes a mathematical model of a thyristorcontrolled direct current motor using the Simulink module of the Matlab simulation environment.
