Exceptions

The exceptions to regulation (EC) 640/2009 and (EU) 4/2014 valid since 01/01/2017 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

The exceptions to regulation (EU) 2019/1781 valid from 01/07/2021 are:

  • Motors which are designed in such a way that they can be operated submerged in a fluid
  • Motors which are completely built into a product (e.g. a gearbox, a pump, a fan or a compressor), whereby the energy efficiency of which cannot be recorded independently of these products
  • Motors with integrated frequency inverters (compact drive units) whose energy efficiency cannot be tested independently of the frequency inverter
  • Specially designed and specified motors which are exclusively for the following operating conditions:
    - At altitudes exceeding 4000 m above sea level
    - At ambient temperatures above + 60° C
    - At ambient temperatures below – 30° C
  • Motors with an integrated brake which is an integral part of the internal motor design and cannot be removed or powered from a separate power source when testing motor efficiency
  • Motors which are specially designed for the safety of nuclear installations in accordance with Article 3 of Council Directive 2009/71/EURATOM
  • Motors with mechanical commutators
  • Totally enclosed self-cooled motors (TENV)
  • Motors placed on the market before 01/07/2029 which are intended to replace identical motors integrated into products placed on the market before 01/07/2022 and marketed specifically for that purpose
  • Multiple-speed motors i.e. Pole-changing motors
  • Motors which are specially developed for electric conveyor vehicles
  • Motors in portable devices whose weight will be carried by hand during operation
  • Motors in hand-held mobile devices which will be moved during operation
  • Motors in wireless or battery-powered devices
  • Motors for underground mining work (mines) are excluded
