MANDATORY USE OF IE3 EFFICIENCY ELECTRICAL MOTORS

04/01/2018

2005/32/CE European directive introduced a new environment friendly design approach for energy-using products, also affecting electrical motors, efficiency of which was defined according to community standards.

(EU) 4/2014 regulation (amending former (CE) 640/2009, effective since June, 16th 2011, when use of IE2 minimum efficiency level became mandatory) applies to squirrel cage induction motors, single-phase and tri-phases, with 50Hz and 60 Hz frequency, from 2 to 6 poles and installed power ranging from 0.75 kW to 375 kW, individually sold on the market or installed onto other devices.

These documents extend mandatory use, starting from January, 1st 2017, to motors having installed power between 0.75 kW and 375 kW, with IE3 minimum efficiency level (IE2 for frequency converter driven ones).

Above mentioned duties do not affect motors with below listed features:

  • poles number higher than 6;
  • rated voltage higher than 1000 V;
  • motors specified to operate wholly immersed in a liquid;
  • motors completely integrated into a product (for example gear, pump, fan or compressor) of which the energy performance cannot be tested independently from the product;
  • brake motors;
  • Motors specified to operate only:

b) At ambient temperatures higher than 60°C or lower than -30°C;

c) At maximum operating temperatures higher than 400°C;

d) In potentially explosive atmospheres (2014/34/EU ATEX directive)
