The Energy-Using Products (EuP) Directive (2005/32/EC) of 6 July 2005 defines the requirements for the eco-friendly design of energy-using products. On 21 October 2009, a revised version of this directive came into force, and the EuP Directive became the Energy-Related Products (ErP) Directive (2009/125/EC). 

The ErP Directive extends the requirements to cover the eco-friendly design of products relevant to energy consumption, but otherwise remains unchanged. As a framework directive, however, it is valid only for those products for which there is what is called an ‘implementing measure’ with product-specific requirements.

For three-phase asynchronous motors, this is the case with the Regulation (EC) 640/2009 and the amending Regulation (EU) 4/2014.

Product-related statutory regulations The Regulation (EC) 640/2009 of 22 July 2009 is the product-related regulation governing drive system technology. 

It defines the efficiency classes for motors supplied directly from the mains, the requirements for the use of variable speed drive technology and the time schedule for implementation.

Scope
The Regulation (EC) 640/2009 applies to threephase asynchronous motors with a squirrelcage rotor for 50 Hz or 50/60 Hz with the following properties:

- Rated voltage up to 1,000 V;
- Rated output from 0.75 to 375 kW;
- Number of poles 2, 4 or 6;
- Rated for continuous operation.

Time schedule for implementation
