Future electric motor regulations

A major change to EU MEPS electric motor efficiency standards came into effect on 1 January 2015, with legislation set to be tightened again in less than two years. But what happens beyond 2017?

Lot 30 of the European Commission’s Ecodesign Directive is a preparatory study into the efficiency performance of electric motors and drives, with new regulations to be set by 2018. Here’s what we can expect.

From 1 January 2018, the following are expected to be added to the regulations:

  • 0.75 to 375 kW 8-pole motors, motors used in explosion-risk areas and brake motors
  • Small induction motors and single-phase motors from 120W
  • A minimum efficiency standard for variable-speed drives (VSDs), allowing those rated at IE2. and above.

From 2020, it’s anticipated that IE2 motors will no longer be allowed, even when paired with a VSD.

From around 2022 we should see the IE4 efficiency level introduced which will provide a 15% reduction in losses.

IES ratings for the efficiency of motor and drive systems are being worked on by a ‘Technical Committee 22X’ and ‘Working Group 6’ in relation to EN 50598-2.
