Permanent magnet motor surpasses IE4

摘要

WEG has again raised the bar for energy efficiency with its new permanent-magnet motor in the W22 series. Already a pioneer in this area with the W22 Super Premium IE4 three-phase induction motors in late 2012, WEG is further consolidating its leadership with even more efficient permanent-magnet synchronous motors. With losses roughly 20% lower than super Premium models, it is among the first Ultra Premium motor on the market that fulfils the present criteria for the potential IE5 energy efficiency class. This makes the W22 one of the most efficient electric motors currently available.
