WEG has contributed to a heritage preservation project at Abbeydale Industrial Hamlet in Sheffield, UK, delivering a motion drive solution that enables the operation of an 1855 steam engine without the use of steam, coal or emissions. The initiative was carried out in partnership with Sheffield Transmission and aimed to keep one of the city’s most important industrial assets in motion while preserving its integrity for future generations. 

Part of Sheffield Museums, the site is a restored 18th-century industrial community featuring original workshops, waterwheels and machinery that illustrate the city’s development into one of the world’s leading steel production centers. Among its highlights is the Davy Brothers steam engine, historically used to power grinding equipment when water levels were insufficient to drive the waterwheel. 

After more than 150 years of operation, running the engine on steam became unfeasible due to safety concerns, environmental regulations and operational challenges. However, maintaining a moving demonstration remained essential to the museum’s educational offering. The challenge was to replicate the engine’s original motion without making any permanent modifications to the historic structure. 

To address this, Sheffield Transmission and WEG developed a bespoke retrofit system, combining modern engineering with heritage preservation. The solution features a WEG W21 high-efficiency IE3 motor, rated at 2.2 kW, selected for its robustness, smooth torque delivery and flexible installation. Its aluminum frame and multimounting design enabled a discreet installation without machining or structural alterations. 

The system is also equipped with a WEG CFW300 variable speed drive (VSD), providing precise control of speed, acceleration and deceleration, allowing the characteristic rhythmic motion of a 19th-century steam engine to be accurately reproduced. With vector and scalar control modes, as well as SoftPLC functionality, the drive was programmed to replicate the original operating profile without imposing mechanical stress on the equipment. 

An integrated human-machine interface (HMI) ensures ease of operation for museum staff, enabling safe and intuitive control of daily demonstrations. To fully preserve the historical integrity of the engine, a custom coupling was developed to connect the motor to the original crankshaft and flywheel assembly, ensuring a fully reversible solution with no impact on the original components. 

Installation followed a detailed engineering assessment, ensuring all components were seamlessly integrated into the existing layout. System calibration enabled historically accurate operating speeds, delivering an educational experience for visitors. 

With the implementation of the solution, Abbeydale Industrial Hamlet once again offers live demonstrations of the steam engine in motion, restoring an important educational and sensory experience. The project demonstrates how modern engineering can be applied sensitively in heritage environments, combining efficiency, safety and sustainability with the preservation of historical assets. 

This initiative reinforces WEG’s ability to deliver tailored solutions for complex applications, combining advanced technology with a deep respect for the specific requirements of each project.
