Heavy duty and high precision don’t normally go hand in hand, but sometimes even the most brutal industrial process can require a level of precision that demands the use of advanced automation solutions.
In a recent project, Austrian specialist automation company, AT Equipment and Services GmbH, was tasked by its customer, A TEC Group, an Austrian engineering and technologies company with a focus on the optimization and efficiency improvement of cement plants, with the development of a precision control solution for two large permanent-magnet (PM) motors.
Deployed in a dual-chamber shredding unit, used to create alternative fuel from recycled waste for a treatment plant, the PM motors used were not a common product for this type of application due to their size. But what they do offer is more accurate speed control versus traditional induction motors – especially when a gearbox is not part of the equation.
AT Equipment and Services, based in upper Austria, has been developing industrial control solutions for over thirty years. For this project it had a choice of suppliers, but ultimately turned to Rockwell Automation because of its impressive Integrated Architecture® automation and safety solutions; and because of the easier integration of the drive solution within its engineering environment software, Studio 5000®.
