Leroy Somer ready for new efficiency standards and directives
The Commission’s regulation 640 of 2009 for application of the ErP (Energy related Product), lot 11 European Directive defines the efficiency classes applicable to 3 phase cage induction motors, whose use will be mandatory in the next years.
It fix the efficiency levels to be attained for machines sold in the European market and outlines the timetable for their implementation. Following the efficiency levels are:
- IE1: Standard efficiency, level equivalent to Eff2
- IE2: High efficiency, level equivalent to Eff1 or “Energy Efficiency” in the United States (EPAct’92), applicable from June 2011
- IE3: Premium efficiency, new in Europe or “Nema Premium” in the United States (EPAct’05) applicable from January 2015 or 2017 depending on the power ratings
- IE4: SUPER PREMIUM efficiency
This fourth class is now in preparation.
LEROY-SOMER, an industrial electric motors manufacturer, is now already able to supply class IE2 totally enclosed and open drip proof motors: LSES/FLSES series (IP55 protection) and PLSES series (IP23 protection), both 2 and 4-pole versions, power up to 375 kW.
These motor series, with aluminium, cast iron or steel frames respectively, are also characterised by their modularity. Indeed, LSES/FLSES and PLSES motors offer not only multiple mechanical options (non-standard flange, special shaft, customised terminal box, etc) but also a wide variety of electrical adaptations (specific connections and voltages, thermal protection, etc).
In order to take energy saving to the needed level, LEROY-SOMER offers a wide range of drive solutions: whether these be in the area of asynchronous technology, particularly with class IE3 high efficiency motors, which can also be combined with variable speed reducers.
