WEG 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.

In combination with a PumpDrive speed control system, the SuPremE motors designed and produced by KSB satisfy all IE4 efficiency requirements (to IEC [CD] 60034-30 Ed. 2). This makes them a lot better already than what is required by EU law for 2017. In order to make this CO2-friendly technology available without delay for building services systems, Frankenthal-based pump manufacturer KSB is launching a special promotion programme. From 1 October 2013, all Etaline variable speed in-line pumps with power ratings from 0.55 kW up to and including 18.5 kW will be supplied with SuPremE motors instead of the previous IE2 motors at no extra charge.
Special eye-catcher at the KSB stand at drinktec in Munich from 16 – 20 September 2013 will be the new SuPremE pump motor. Developed by KSB, it is a real highlight where saving energy is concerned. With its synchronous reluctance principle the motor provides users with a technology that is ideally suited to fulfil all future requirements for energy-efficient drives of pumps. It meets the planned IE4 efficiency requirements to IEC/CD 60034-30 Ed. 2 already today.
