ABB has extended its IE5 synchronous reluctance motor (SynRM) range with three new frame sizes, giving customers access to Ultra-Premium efficiency in a wider set of applications. The addition of sizes 90, 100, and 112 extends the portfolio’s coverage from 0.75 kW up to 450 kW.
The motors, which contain no magnets or rare earth materials, are designed to operate in high-volume, continuous-duty, and space-constrained environments. With speed options up to 3600 RPM, they are suited to pumps, fans, and compressors — particularly when paired with ABB’s variable speed drives.
“Smaller motors are often deployed in high volumes and in continuous-duty or space-constrained environments where thermal performance, precise control, and high efficiency under partial load are critical,” said Stefan Floeck, President IEC LV Motors, ABB. “With our expanded SynRM range, we’re ensuring that every motor, no matter the size, plays its part in helping boost productivity for our customers while cutting emissions.”
ABB claims the motors reduce energy losses by up to 40% compared with IE3 models, translating to significant long-term operating cost savings. A single 90 kW SynRM motor can save around €79,800 and cut 95,760 kg of CO₂ emissions over a 20-year lifetime. With dozens of smaller motors typically running across industrial sites, payback periods are often measured in months rather than years.
The extended portfolio also forms part of the ABB EcoSolutions™ programme, which provides third-party verified Environmental Product Declarations to support customer decision-making on sustainability and circularity.
ABB positions the SynRM range as a step towards IE6 “Hyper-Efficiency,” already available on selected models above 90 kW. These motors achieve up to 20% lower losses than IE5, setting a technical benchmark in industrial energy efficiency.
