LenzeAs part of 2011's upcoming XPAR Directive 2009 / 125 / EG, Lenze not only considers motors, but also takes a close look at complete powertrains in an application. IE2 for power from 0,75 to 375 kW for two-, four- and six-pole three-phase motors - and with no transitional periods: With the new version of the European Ecodesign Directive, the energy efficiency class IE2 according to IEC 60034-30 becomes 2011 in summer. Both "L-force" AC motors MH from Lenze, the higher efficiency is not, as is often the case, at the expense of undesired size jumps.

The specialist for drive and automation technology has succeeded in largely avoiding these in order to simplify the migration to IE2. Consequently, conversions - for example, as part of a retrofit - easier to carry out. But an efficiency-optimized component alone will not make an efficient powertrain for a long time. That is why Lenze, as a system supplier within the L-force drive and automation platform, combines the IE2 motors with highly efficient axial and angular gearboxes.

The use of an L-force geared motor, consisting of an IE2 three-phase motor and a GKR bevel gearbox, reduces the energy requirement by around 1% compared to a conventional solution with a worm gear and IE41 three-phase motor. Another advantage: The high efficiency reduces the heat loss and thus extends the service life of the components, including longer maintenance intervals and thus increasing availability.

On the 16. June 2011 sets the first stage of the ErP Directive 2009 / 125 / EC. Then the energy efficiency in the electric drive technology will receive not only business management but also a legal, Europe-wide binding rating.
