A metal-processing plant in Eastern Europe recently faced a growing challenge: its aging rolling-line drive system was struggling to deliver stable torque at low speeds. This instability caused sheet-thickness variations that triggered repeated product rejections and forced operators to slow down production to maintain quality standards. The losses accumulated quickly, prompting management to investigate a long-term solution.

After several technical evaluations, the engineering team opted to replace the outdated drive unit with a Simo motor configured as a high-reliability DC industrial motor. The choice was driven by its precise torque control, fast dynamic response, and compatibility with the plant’s existing DC drive architecture—minimizing retrofit time and cost.

The new motor was installed during a weekend shutdown, and by Monday morning, the results were already apparent. Thickness variation dropped to within the plant’s strict tolerance limits, eliminating the need for repeated adjustments. Operators reported smoother line behavior, especially during slow-speed startup, where the previous system frequently caused sudden surges.

Within six weeks, quality-related scrap decreased by nearly 20%, and overall production efficiency improved enough to offset the full cost of the upgrade. Encouraged by the performance, the plant has begun assessing additional lines for similar modernization.
