Goals of the 4E Motor Systems Annex are to work for harmonization of standards and to promote high-efficiency electric motors in appliances.
Major measures for improvement include:
Although motors are traded globally, market barriers for efficient motors and other components exist due to varying grid frequency (60Hz and 50Hz), not aligned testing standards and different marking schemes, higher upfront capital investment and split incentives for purchasers and users.
Engineering lacks a common understanding of viewing the total motor system and its life cycle cost as target for optimization.
Mandatory minimum energy performance standards MEPS are considered (after ample experience in USA, Canada, Australia, New Zealand, etc.) to be the most effective political instrument to move the motor market rapidly and successfully up to high market shares of efficient motors and other systems components.
