WebIEC Efficiency Classes. In March 2014 the standard IEC 60034-30-1 was published. It replaced standard IEC 60034-30:2008, which defined three efficiency levels for three … Webto the new measuring method will be lower. For example, an 11 kW, 4-pole EFF1 motor with 91.0% efficiency is physically identical with a IE2 motor with 89.8% efficiency. The efficiency class system specified under IEC 60034-30 is valid for low voltage three-phase cage-induction motors with the following specifications: • Rated voltage up to ...

WebHowever, the efficiency of the electric motors tends to decrease with the speed reduction, making them a source of losses when adopting the speed control. In this paper, an all-variable speed centrifugal chiller model is developed in SimulationX, as well as synchronous reluctance motors (SynRM) and high-efficiency induction motors models, and … Web1 feb. 2009 · MEPS for IEC motors is a relatively new concept. Currently, there are no mandatory motor-efficiency standards for Europe, but talks indicate they may be adopted by 2012. MEPS have existed for many years in Australia and New Zealand.
