Motor Efficiency and Legislation: In Europe, the modern era of efficient motors may be said to have begun in 2000 with a voluntary agreement on motor efficiency between European Motor Manufacturer Association (CEMEP) and the European Commission. The current, mandatory, efficiency level across a wide power rating range required of motors sold in Europe is embodied in the EU MEPS (European Minimum Energy Performance Standard) scheme, introduced in July 2009.
The EU MEPs not only raises the efficiency standard of motors sold in Europe, it also links Europe’s requirements to international standards. Similar initiatives elsewhere are helping to harmonise motor efficiency standards globally. EU MEPS covers 2-, 4- and 6-pole single speed, three-phase induction motors in the power range 0.75 to 375 kW, rated up to 1000 V and on the basis of continuous duty operation. The implementation timeline is shown in Figure 116, and a comparison with standards in the United States and standards in individual European countries is shown in Figure 117.

Notes
|
Phase 1: From 16 June, 2011
|
Motors must meet the IE2 efficiency level
|
IE2/ High efficiency- comparable to Eff1 (European CEMEP agreement)
|
Phase2: From 1 January, 2015
|
Motors with a rated output of 7.5 – 375 kW must meet EITHER the IE3 efficiency level OR the IE2 level if fitted with a variable speed drive
|
IE3 / Premium efficiency- extrapolated from IE2 with ~15% lower losses
|
Phase 3:From 1 January, 2017
|
Motors with a rated output of 0.75 – 375 kW must meet EITHER the IE3 efficiency level OR the IE2 level if fitted with a variable speed drive
