Abstract

The study of the dynamic characteristics of two- and three-engine thyristor electric motors with constant current, in the case of a multi-motor control system, taking into account the elasticity of mechanical shafts are reviewed in this article. Such multimotor control systems are widely used in metallurgical production. For example, in sheet rolling mills, where in the mechanical part there are moments of significant dynamic curvature. The paper also reviews the functional and structural schemes of a cohesive multi-engine system. In the case of a multi-motor touring electric motor system, the structural scheme of a two-engine drive was studied in order to determine the correct load distribution. The study was conducted using a computer program - MATALAB using 150 kW and 300 kW engines. A Kalman filter-like observation device is used to quench the binding oscillations generated in the system. The quality indicators obtained from the transient mode studies are close to the optimal parameters, so the considered system is suitable for multi-motor rolling mills.
