WEG: New permanent-magnet motor surpasses IE4 standard

1
18

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.

Using innovative design, the W22 permanent-magnet motor combines unique high efficiency with compact size. Along with raising efficiency, WEG optimised motor performance to achieve lower noise and vibration emissions as well as especially low maintenance.

The new permanent-magnet motors in the W22 series are AC synchronous motors driven by CFW11 frequency inverters. The CFW11 frequency inverters are provided with specific software for open-loop speed control of permanent-magnet motors. The software is based on a special drive strategy designed to maximise the torque per ampere. This approach makes the combination of a W22 permanent-magnet motor and a CFW11 frequency inverter a very efficient drive system that is able to deliver constant torque over the entire operating range.
