ABB has broken its own world record for energy efficiency in large synchronous electric motors with a new motor designed in line with its Top Industrial Efficiency (TIE) initiative which delivers equipment which exceeds standard performance benchmarks. ABB’s TIE motors and generators are engineered to surpass current efficiency benchmarks, helping customers reduce electricity usage, operating costs, and total cost of ownership (TCO) without compromising performance or adding complexity.
The motor, destined for a steel plant in India, has achieved an efficiency rating of 99.13% during testing, a substantial improvement over ABB’s previous world record of 99.05% set in 2017. The efficiency rating is the ratio between the energy a motor draws and the amount it turns into motion. The theoretical limit is 100% efficiency. Getting closer to this target becomes increasingly challenging in terms of the motor design and manufacture. This is why the previous world record stood for 8 years.
Opting for a TIE-optimized motor, rather than the standard design with 98.64% efficiency level, will enable the customer to save around 61 GWh of energy and $5.9 million in electricity costs over a 25-year lifespan – equivalent to four days of peak output from the world’s largest offshore wind farm. It will also support avoiding 45,000 tons of CO? emissions, comparable to removing 10,000 cars from the road for a year. The scope for savings and avoided emissions is even greater in other countries where electricity is more expensive.
The motor will drive an air separation unit (ASU) that will liquify atmospheric air so that the oxygen and nitrogen can be separated out to provide pure 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”, said 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.”
ABB's TIE initiative addresses a major gap in energy efficiency standards for large motors (3 MW+), which, despite being a small part of the global motor base, consume about 25% of all motion-related energy.
Setting the new world record on efficiency reflects ABB’s ongoing commitment to further optimizing the motor's electrical and mechanical construction, drawing on extensive application knowledge and over a century of experience in manufacturing electric motors. This achievement is particularly significant given that the average efficiency for this type of synchronous motor typically ranges between 98.2 and 98.5%.
ABB is a global technology leader in electrification and automation, enabling a more sustainable and resource-efficient future. By connecting its engineering and digitalization expertise, ABB helps industries run at high performance, while becoming more efficient, productive and sustainable so they outperform.
