EU Ecodesign Regulation 2019/1781 New Efficiency Limits

What are the regulation objectives?

Lower consumption of electricity

Minus 100 million tonnes of greenhouse gases by 2030

Less CO2 in the atmosphere

How will it affect you?

Step 1 - 1 July 2021 Electric Motors

  • Minimum efficiency equal to IE2 for three-phase asynchronous electric motors from 0.12 to 0.55 kW

  • Minimum efficiency equal to IE3 for three-phase asynchronous electric motors from 0.75 to 1000 kW

Scope

Asynchronous electric motors, rated for operation on a 50 Hz, 60 Hz or 50/60 Hz sinusoidal voltage, rated voltage above 50 V and up to and including 1000 V and continuous duty operation (S1, S3 ≥ 80%, S6 ≥ 80%).

For the first time the regulation will include:

  • All three-phase single speed motors up to 8 poles
  • Brake motors
  • Ex motors for explosive atmospheres
  • TEAO motors (Totally Enclosed Air Over – IC418)

Please note that the IE2+VSD option will no longer be permitted.

Three-phase Motors Efficiency Requirements

Step 1 - 1 July 2021 - Variable Speed Drives (VSDs)

Scope

VSDs with 3-phase input from 0.12 kW to 1000 kW, rated voltage above 100 Vand up to 1000 V

Main Exceptions

  • Regenerative drives
  • VSDs with a Total Harmonic Content below 10% (THD < 10%)

Step 1 - 1 July 2021 Electric Motors

Scope

Asynchronous electric motors, rated for operation on a 50 Hz, 60 Hz or 50/60 Hz sinusoidal voltage, rated voltage above 50 V and up to and including 1000 V and continuous duty operation (S1, S3 ≥ 80%, S6 ≥ 80%).

For the first time the regulation will include:

  • Single-phase electric motors
  • Ex eb increased safety motors
  • There will be a further increase in efficiency for three-phase motors, which will see the introduction of the IE4 class:
  • Motors with a rated output from 75 to 200 kW with 2, 4, 6 poles, with the exclusion of brake motors and motors with Ex eb, Ex ec, Ex d, Ex de and Ex t protection

Single-phase Motors Efficiency Requirements

Three-phase Motors Efficiency Requirements

Main exclusions from the scope

• Totally Enclosed Non-Ventilated motors (TENV)

• Motors completely integrated into a product

• Motors specifically designed and specified to operate exclusively:

1) at altitudes exceeding 4000 metres above sea level

2) where ambient air temperatures exceed 60°C

3) in a maximum operating temperature above 400°C

4) where ambient air temperatures are less than -30°C

5) where the water coolant temperature at the inlet to a product is below 0°C or above 32°C

• Motors placed on the market before 1 July 2029 as substitutes for identical motors integrated in products placed on the market before 1 July 2022, and specifically marketed as such

• Multi-speed motors, i.e. motors with multiple windings or with a switchable winding, providing a different number of poles and speeds
