International Directive for Energy Efficiency
The energy classes for drives and for systems are defined in the international standard IEC 61800-9. In Europe it is referenced as EN 61800. These standards define how to calculate energy classes IE1 and IE2 for drives and IES1 and IES2 for systems. Driven by the Ecodesign Directive, the requirements for energy efficiency in drive technology continue to increase.
New minimum efficiency requirements apply in July 2021.
