KSB motors IE5 classified

Wednesday, March 22nd, 2017 von admin

The KSB SuPremE motor made by the Frankenthal pump manufacturer KSB has been IE5 classified since January 2017. The motor meets the requirements of IE5 (IEC/TS 60034-30-2), the highest of energy efficiency classes for variable speed electric motors; compared with IE4, motor losses are reduced by a further 20 percent.

Unlike conventional synchronous motors this drive is made without any magnetic materials such as rare earths that are categorised as critical raw materials since their extraction causes severe environmental impacts in their countries of origin.

WEG: New permanent-magnet motor surpasses IE4 standard

Thursday, April 10th, 2014 von admin

WEG2177_Bild1WEG has launched a permanent-magnet motor that fulfils this demanding requirement, making it one of the first to qualify for the IE5 Ultra Premium Motor designation.  With losses roughly 20 % lower than Super Premium models, it is among the first Ultra Premium motors on the market that fulfil the present criteria for the potential IE5 energy efficiency class. This makes the W22 permanent-magnet motor one of the most efficient electric motors currently available world-wide.
