Regulation Nos. 640/2009 and 4/2014

From 1 January 2017, a new phase of the Regulation will be implemented.

 IE2 and IE3 motors (0.75 kW to 375 kW) can only be marketed or integrated into machinery if they are equipped with a variable speed drive.

Manufacturers of motors and machinery are once more encouraged to innovate in terms of energy efficiency in order to attain the objectives set for 2020 by the Regulation.

As a reminder, the Regulation implements Directive 2005/32/EC that sets the energy efficiency requirements for energy-using products.

This Regulation is aimed more particularly at the ecodesign requirements for electric motors. It follows findings from a study concluding that an improvement in drive systems across Europe between now and 2020 could enable a 20-30% reduction in energy consumption, thus avoiding the discharge of 63 million tonnes of CO2 and saving 135 billion kWh/year.

It is also based on standard IEC 60034-30-1 which defines an energy efficiency classification system for electric motors.

This method of calculating energy efficiency is subject to IEC 60034-30-2.

  • Classification
    • IE1 = standard efficiency
    • IE2 = high efficiency
    • IE3 = premium efficiency
    • IE4 = super premium efficiency

This classification covers the following motors:

    • Single and three-phase motors at 50 and 60 Hz
    • 2, 4, 6 or 8 poles
    • Power range 0.12 to 1000 kW
    • Voltage 50 V to 1 kV
    • Motors capable of continuous operation at their rated output with a temperature rise within the insulation temperature class
    • Motors with an ambient temperature within the range of -20°C up to +60°C
    • Motors capable of operating at a rated altitude up to 4000 m above sea level.

Motors excluded:

    • Motors with 10 or more poles
    • Motors fully integrated into a machine (e.g.: pump, fan or compressor)
    • Brake motors, where the brake cannot be removed or separately operated.
  • Changes to IEC 60034-30

IEC 60034-30-1 published in March 2014 replaces IEC 600034-30 (2008) which covered asynchronous three-phase motors only.

    • This extension to the standard concerns mainly:

- A wider range of motors including asynchronous single-phase motors and a wider power range from 0.12 kW up to 1000 kW
- The addition of a fourth engine efficiency classification, IE4 and IE5, are planned but not yet defined.
- Scope for further restrictive measures.

Schedule for the Regulation 

  • Phase 1 (06/2011)

As of this date, manufacturers can no longer market IE1 motors and machine designers can no longer integrate such motors into their designs.

  • Phase 2 (01/2015)

IE2 and IE3 motors (7.5 kW to 375 kW) can only be marketed or integrated into machinery if they are equipped with a variable speed drive.

  • Phase 3 (01/2017)

IE2 and IE3 motors (0.75 kW to 375 kW) can only be marketed or integrated into machinery if they are equipped with a variable speed drive.

 The amendment in March 2014 of IEC 600034-30 enabled the addition of a new classification (IE4) and planned for a fifth (IE5). These new classifications allow scope for further development of the Regulation, like euro 4/euro 5/euro 6 for vehicles.
