CONTROL SYSTEM OF TWO-MOTOR ELECTRICAL DRIVE BY THE REGULATION OF EXCITEMENT AND AUTOMATIC DISTRIBUTION OF LOADING

Abstract

In the paper we present the system of two-motor electrical drive for modern press mechanisms of
paper machines, that has one regulator and individual regulators for anchor currents and excitement currents of
the motors by their supply from common converter of the paper machine. Mathematical model of the dynamics of
electrical drive by taking into account elasticities of mechanical transmissions is given. For tuning of the regulators,
sensors of currents and corrector, which provide optimized dynamical characteristics of the drive and proportional
distribution of load between the motors without additional contours and regulators are suggested
