ABB Motor Sets New Efficiency Record

29 May 2025 CW Team

The motor's exceptional efficiency is projected to deliver significant cost savings for the steel plant. Over its 25-year lifespan, the customer is expected to save approximately $5.9 million (around £4.7 million) in electricity costs, representing an energy saving of 61 GWh. This investment in energy efficiency is anticipated to have a rapid payback period of just over three months.

Beyond the financial benefits, the new motor will also contribute substantially to environmental sustainability. The projected energy savings are equivalent to preventing 45,000 tonnes of CO$_2$ emissions, comparable to removing 10,000 cars from the road for a year. The potential for even greater savings and emission reductions exists in countries with higher electricity prices.

The motor is destined to power an air separation unit (ASU), which will liquefy atmospheric air to separate oxygen and nitrogen – essential gases for the steelmaking process.

"ABB is on a mission to help industries outrun – leaner and cleaner – and this project shows how our products go beyond standards with our Top Industrial Efficiency (TIE) initiative, which delivers large motors and generators with the highest possible energy efficiency,” stated Brandon Spencer, President of ABB Motion. “This initiative helps our customers boost profitability since electricity costs are, by far, the largest component in the total cost of ownership (TCO) of this type of motor, at the same time they are also cutting their carbon emissions.”

The TIE initiative specifically addresses a notable gap in energy efficiency standards for large motors (3 MW and above). While these motors represent a small fraction of the global motor base, they account for roughly 25 per cent of all motion-related energy consumption.

This new world record underscores ABB's ongoing dedication to optimising both the electrical and mechanical aspects of motor design. The achievement is particularly impressive given that the typical efficiency for this type of synchronous motor generally ranges between 98.2 and 98.5 per cent, reflecting ABB's century of expertise in manufacturing electric motors and extensive application knowledge.

A massive synchronous electric motor, developed by ABB for an Indian steel plant, has achieved a new world record for energy efficiency. Designed under ABB's Top Industrial Efficiency (TIE) initiative, the motor registered an unprecedented 99.13 per cent efficiency rating during testing. This achievement surpasses ABB's own previous record of 99.05 per cent, set in 2017, and highlights the company's commitment to pushing the boundaries of industrial efficiency.The motor's exceptional efficiency is projected to deliver significant cost savings for the steel plant.

India Leads Global AI Readiness but Implementation Lags

Indian companies lead global averages across all eight artificial intelligence readiness indicators tracked by JLL, but only 19 per cent have started making changes to their workplaces, according to the JLL 2026 Future of Work Survey.The study found that 77 per cent of Indian business leaders expect AI to change their office requirements, creating a 58-percentage-point gap between awareness and implementation. The survey covered more than 2,200 CEOs, CFOs and real estate leaders across 21 countries during the first quarter of 2026.Despite concerns over automation, 58 per cent of Indian leaders..

Three WOLFF Cranes Build Riyadh Cable-Stayed Bridges

Three WOLFF 180 B luffing jib cranes are supporting the construction of two cable-stayed bridges alongside the existing Wadi Laban Bridge in Riyadh, Saudi Arabia. The project is being developed for the Royal Commission for Riyadh City and executed by the ICRC joint venture comprising IC Ictas and Al Rashid Trading & Contracting Company.The cranes are handling lifting operations including formwork, reinforcement, concrete placement, work platforms, surveying equipment and other construction materials. Each crane is fitted with a 40 m jib, reaches a hook height of 157 m and offers a maximum ..
