Numerous standards or regulations are currently used to define the efficiency of electric motors (NEMA, EPAct, NRCan, CEMEP, COPANT, AS/NZS, etc), and others are in preparation.

It is becoming increasingly difficult for manufacturers to design motors for a global market and for users to understand the differences and similarities between standards in different countries.

Standard IEC 60034-30 defines the principle to be adopted and brings global harmonisation to energy efficiency classes for electric motors throughout the world.

Directive 2005/32/EC (6 July 2005) from the European Parliament has established a framework for setting the eco-design requirements to be applied to “energy-using products”. These products are grouped in lots. Motors come under lot 11 of the eco-design programme, as do pumps, fans and circulating pumps.

European directive EuP - lot 11 was voted on july 2009. It is based on standard IEC 60034-30 and define the efficiency classes whose use will be mandatory in the future. It specifies the efficiency levels to be attained for machines sold in the European market and outlines the timetable for their implementation.
