Energy efficiency requirements for general purpose electric motors: Accelerating the global adoption of energy efficient electric motors

These Guidelines are an update of the original report published in 2017, to assist developing countries and emerging economies transform their markets to adopting energy efficient motor systems. The Guidelines provide ready templates to set minimum efficiency performance standards (MEPS) for (a) induction motors, (b) variable speed drives, (c) fans driven by motors with an electric input power between 125 W and 500 kW, (d) rotodynamic water pumps for pumping clean water, and (e) air compressor packages. The Guidelines are structured as building blocks that may be combined based on the market structure and practices in each individual country or region. These include all the key elements that are needed for this type of regulation: (i) definitions, (ii) scope, (iii) performance requirements, (iv) product information requirements, (v) applicable test methods and (vi) compliance criteria.
