CORRECTION MECHANISM FOR BALANCING DRIVING TORQUES IN AN OPENCAST MINING STACKER WITH AN INDUCTION MOTOR AND CONVERTER DRIVE SYSTEM

Correction Mechanism for Balancing Driving Torques in an Opencast Mining Stacker with an Induction Motor and Converter Drive System

This article describes a correction mechanism for balancing torques in moving drives.The steering system is controlled by a programable logic controller (PLC), a field-oriented control (FOC) algorithm in the drive inverter system, Process Fieldbus (PROFIBUS), and a Decentralized Hoodie Peripherals (DP) network.The mechanism was applied in an openca
