Electric motors and motor systems in industrial and infrastructure applications with pumps, fans and compressors in buildings are responsible for 53% of the world’s total electricity consumption. New and existing technologies offer the potential to reduce the energy demand of motor systems across the global economy by 20% to 30% with short payback periods.
4E’s Electric Motor Systems Annex (EMSA) raises worldwide awareness of the efficiency potential of motor systems and provides guidance and tools to exploit the energy performance of new and existing motor systems worldwide.
The two reports Policy Guidelines for Motor Driven Units investigate policy options for harmonising standards and regulations for pumps, fans, compressors and are now available in Chinese. The first report (Part 1)
The IEA 4E EMSA organised an international round robin testing programme for converters in cooperation with IEC SC22G/WG, to support the revision of IEC 61800-9-2 with science-based evidence. The Report on Round
In Europe, sensors and data-analytics for optimising motor driven systems can bring an additional 50-100 TWh electricity savings per year by 2030, together with additional benefits such as lower maintenance and production

This report, available in Chinese, proposes policy options for the international alignment of technical standards and minimum energy performance standards for pumps, fans and compressors.
This report, available in Chinese, describes existing standards and regulations for pumps, fans and compressors.
This report summarises the results of the IEA 4E EMSA international Round Robin testing programme for converter losses, implemented in cooperation with IEC SC22G/WG18.
