ABB has introduced the anticipated IE6 efficiency level in a magnet-free SynRM design, marking the latest development in the well-proven SynRM technology.

These motors are expected to appeal to innovative customers who want to future-proof their fleet by adopting the highest level of energy efficiency commercially available.

Early adopters of IE6 hyper-efficiency motors will benefit from reduced energy costs and increased productivity while moving ahead of current sustainability targets, according to ABB.

"Motor-driven systems in industrial facilities are major users of electricity and therefore maximizing their efficiency offers huge potential to cut emissions and help meet climate change targets. Using our new magnet-free SynRM motors reaching efficiency levels expected for future IE6 will also take energy savings to the next level," says Stefan Floeck, Division President IEC Low Voltage Motors, ABB Motion. "SynRM is a perfect example of the commitment to innovation built into our DNA. Because the IE6 SynRM is the same size as the equivalent IE3 induction motor it is an easy and straightforward replacement for legacy motors. That makes it possible for customers to upgrade to modern, high efficiency products to future-proof their operations in a world of fluctuating energy costs."

ABB's wide range of SynRM motors has set the benchmark for magnet-free design, progressing through IE4 to IE5 versions launched in 2019. IE6 is assumed to be the next logical step, demonstrating the capability and technical superiority of SynRM technology.

SynRM combines the performance of PM motors with the simplicity and service-friendliness of induction motors to achieve high energy efficiency, ensuring a short payback time.

The rotor has neither magnets nor windings, suffering virtually no power losses. The design requires no rare earth metals and offers a high level of usability due to the wide availability of suitable variable speed drives (VSDs).
