#HM14 Super premium induction motor!

WEG is presenting its new and highly energy-efficient permanent-magnet motors in the W22 series at Hannover this year (Hall 15, StandF11). With a rated efficiency of 96.6% and significantly lower losses than IE4 motors, they are among the first commercially available motors that conform to the recently formulated criteria for a potential IE5 energy efficiency class. With the launch of this  Super Premium family of induction motors in late 2012, WEG was among the first to offer a full range of motors conforming to the as-yet unratified IE4 standard. Another WEG innovation at the fair is the upgraded W22x series of explosion-proof motors, which are now available in IE4 versions on request as well as standard IE2 and IE3 efficiency classes.


WEG takes the lead in energy efficiency with the new IE5 permanent-magnet induction motor

For mechanical and plant engineering firms, it’s time for action because EU Motor Efficiency Regulation EC 640/2009 stipulates that starting in 2015 or 2017, IE3 induction motors, or alternatively IE2 motors driven by frequency converters, must be used in most industrial applications. As a force in the development of energy-efficient drive solutions, WEG aims to offer a full range of options. Users can comply with the regulations by opting for a high-performance W22 IE2 motor in combination with a frequency converter in the CFW 11 or CFW 11M series, or by opting for the direct approach of a W22 motor with an IE3 or IE4 rating. Highly energy-aware enterprises can now go even further and choose the new permanent-magnet motor, which has significantly lower losses than the Super Premium model and conforms to the specifications of the potential IE5 regulation.

The upgrade of the W22x series of motors for explosion-proof applications is also motivated by considerations of energy efficiency and the Motor Efficiency Regulation. Up to now special applications such as explosion protection have been exempt from the efficiency regulations for standard induction motors. On its own initiative, WEG resolved to give users the option for maximum energy efficiency in this demanding application area as well. Accordingly, the drive specialists have now expanded their portfolio of explosion-proof W22x motors with versions conforming to energy efficiency class IE4, which sets them apart from most of the competition.

Additional product highlights at the Hannover trade fair expand the existing portfolio to include the high-performance gear units and gear motors of WEG’s subsidiary Watt Drive. With its broad portfolio, WEG is further expanding its presence as a system provider in Europe.
