Energy Regulations & Standards

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

Exceptions

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
