History

 

Since 2009, the European Union (EU) Commission has been working towards reducing energy consumption through legislation governing eco-design requirements for all energy-related products. At that time, it was estimated that there were about 85 million large electrical motors in operation throughout the EU, consuming around 65-70% of all energy used in industry.

 

To address this, the Commission enacted Regulation (EC) No 640/2009, which mandated that single-speed, three-phase, 50 Hz or 50/60 Hz squirrel cage induction motors for continuous duty, with 2 to 8 poles and power ratings between 0.75 kW and 375 kW, must meet specific efficiency levels.

 

According to that regulation:

 

  • Motors with a rated output of 7.5 to 375 kW had to meet the IE2 efficiency level by 16 June 2011.
  • Motors with a rated output of 0.75 to 375 kW had to meet the IE2 efficiency level by 1 January 2015.
  • From 1 January 2017, motors with a rated output of 0.75 to 375 kW had to meet the IE3 efficiency level, or the IE2 efficiency level if equipped with a variable speed drive.

 

 

Commission Regulation (EU) 2019/1781

 

Commission Regulation (EC) No 640/2009 remained in effect until 30 June 2021 and was subsequently repealed and replaced by Commission Regulation (EU) 2019/1781, which introduced updated requirements and came into force on 1 July 2021. This marked the implementation of the next phase of the directive, broadening the scope of the regulations to cover a wider range of electric motors. The prescribed changes are estimated to deliver roughly 10 TWh of energy savings by 2030, significantly reducing greenhouse gas emissions.

 

The new regulation expands the scope and introduces stricter efficiency requirements for motors and variable speed drives (VSDs). For the first time, it includes 60 Hz motors, brake motors with external brakes, and motors designed for use in hazardous environments. Additionally, VSDs with a rated voltage above 100V and up to and including 1000V AC are now included within the scope.

 

Here's a brief outline of the new energy efficiency levels and requirements:

 

Energy Efficiency Requirements for Electric Motors:

IE2 Efficiency Level:

  • Motors with a rated output between 0.12 kW and 0.75 kW.

IE3 Efficiency Level:

  • Motors with a rated output from 0.75 kW to 1000 kW (inclusive).
  • Both 2-, 4-, 6-, and 8-pole motors are included.

IE4 Efficiency Level:

  • Motors with a rated output from 75 kW to 200 kW.

IE5 Efficiency Level:

  • This regulation encourages the development and market adoption of motors with even higher efficiencies (beyond IE4), although IE5 is not yet mandated.

 

Energy Efficiency Requirements for Variable Speed Drives:

IE2 Efficiency Level:

  • Variable speed drives with a rated output between 0.12 kW and 1000 kW.

 

Key Dates for Implementation:

 

As of 1 July 2021:

  • IE3 mandatory for motors with rated outputs between 0.75 kW and 1000 kW.
  • IE2 mandatory for motors with rated outputs between 0.12 kW and 0.75 kW.
  • IE2 mandatory for variable speed drives with rated outputs between 0.12 kW and 1000 kW.

  • Motors integrated into products where their energy performance cannot be tested independently.
  • Motors designed for variable speed operations that do not comply with fixed speed motor test conditions.

 

 

Variable Speed Drives (VSD)

 

From July 1st, 2021, Variable Speed Drives (VSDs) have also fallen within the remit of the EU 2019/1781 regulation. Initially, the regulation covers 3-phase standard VSDs with power ratings from 0.12 kW to 1000 kW and a rated voltage above 100V up to and including 1000V. The power losses of VSDs rated for operating with motors in this power range shall not exceed the maximum power losses corresponding to the IE2 efficiency level.

 

Major exemptions are:

  • VSDs integrated into a product whose energy performance cannot be tested independently from the product.
  • Regenerative drives.
  • Multiple AC-output drives.

 

The regulation is valid for:

  • New motors/VSDs placed on the market for the first time.
  • Replacement motors, as substitutes for identical motors integrated into products placed on the market until 1st July 2022 and specifically marketed for this purpose, do not have to meet the requirements of the new regulation and may be supplied according to (EC) 640/2009 until 1st July 2029.

 

 

Objective:

The regulation aims to improve the energy efficiency of electric motors and drives, thereby reducing energy consumption and greenhouse gas emissions in line with the EU's broader climate and energy goals.

 

These requirements are intended to drive innovation in motor and drive technology, leading to more energy-efficient products on the market and ultimately contributing to the EU's sustainability objectives.
