         2. EFFICIENCY


         In 1998 the European Committee of Manufacturers of Electrical  Machines and Power Systems (CEMEP) issued a voluntary agreement of
         motor manufacturers on efficiency classification with three efficiency classes namely Eff1, Eff2, and Eff3, which can be treated as the first
         concrete approach towards efficiency in the European region. The lack of regularity authority behind the agreement have limited the
         success of this formation and helped to convert as low as 1% of Eff3 low-efficiency motors to Eff1 high-efficiency motors in about 10
         years.

         International Electrotechnical Commission  (IEC) conducted a comprehensive study within this period of time and came up with  two
         efficiency standards of which latest versions are 60034-30-1:2014 where IE codes are defined and 60034-2-1:2014 where test methods
         are specified.

         IEC  is  an  organization  that  defines  efficiencies,  test  procedures  by  publishing  standards  but  it  is  not  a  body  that  is  controlling  the
         application  of  these  standards.  They  are  rather  controlled  via  MEPS  (Minimum  Energy  Performance  Standards)  which  are  made
         mandatory by government energy efficiency bodies in the relevant countries. In the European Union, Eu regulation 640/2009 and the
         supplement 04/2014 is a force to regulate energy efficiency of industrial motors in the industrial environment. In Turkey, it is regulated
         by  communique  28197  (SGM-2012/2)  dated  07/02/2012  on  ecodesign  requirements  for  electric  motors  and  the  supplement  29294
         (SGM-2015-2015/15 dated 13/03/2015.

         The aim of these legislative regulations in the European Union and Turkey is to maintain usage of motors not less than IE3 efficiency
         level as from 1 January 2015 (motors between 7,5kW – 375kW) and 1 January 2017 (motors between 0,75 – 7,5 kW) hence reduce Co2
         emissions worldwide.

         The table below lists the scope of the international standard IEC 60034-30-1 and of Regulation 640/2009
