IE5 synchronous reluctance motors can halve losses

摘要

ABB HAS ANNOUNCED that its SynRM synchronous reluctance motors now comply with the IEC's new IE5 ultra-premium energy efficiency class, achieving energy losses that are up to 50% lower than those of IE2 induction machines. ABB introduced the SynRM technology in 2011 and applications have demonstrated energy savings of up to 25%. The SynRM technology combines the performance of permanent magnets with the simplicity and ease of servicing of induction motors. The motors do not contain rare earth materials, and operate with low bearing and winding temperatures for enhanced reliability and long service lives. They are also claimed to cut noise levels.
