Technological Advance of Drive System for Paper Manufacturing Facilities

Abstract

There are a large number and a wide range of capacity of motors and drives applied to pulp and paper industries. Variable-speed drives are widely used for not only line-drive applications such as paper machine, winder and off-machine coater but also single-drive applications as boiler and paper machine auxiliary equipment. High performance and large-capacity variable-speed drives have been developed with advanced technology and innovation, changing from DC to AC, analog to digital control. This technological innovation includes digital technology with power device, main circuit and microprocessor, control technology with AC vector control and system network technology with high-speed communication.This article describes the technological advance and history of drive system in the field of paper manufacturing facilities, introducing the latest AC drive system.
