Energy Regulations & Standards

The standards for energy efficiency differ greatly around the world not only in the implementation but also in the introduction.

Geared motors are exempt from MEPS
(cf. IE2) since 2006


The exceptions to regulation (EC) 640/2009 and (EU) 4/2014 are:

  • Motors designed to operate fully submerged in a liquid
  • motors that are completely integrated in a product (such as a transmission, pump, fan or compressor) whose energy efficiency cannot be determined independently of this product
  • at heights above 4,000 metres above sea level
  • at ambient temperatures above 60° C
  • at maximum operating temperatures above 400 °C
  • at ambient temperatures below -30° C (all motors) or ambient temperatures below 0° C (air cooled motors)
  • with coolant temperatures at product intake below  5° C or over 25° C
  • in areas with a potentially explosive atmosphere as mentioned in Directive 94/9/EC of the European Parliament and the Council
  • Brake motors
