New Ecodesign Directive from July 2021: What you need to know
Climate and environmental protection are important topics in today's society. They affect both the private and the commercial sector. The production, operation and disposal of energy-related products play an important role and need corresponding standards. In the directive, the minimum efficiency was further tightened so that IE2 motors, for example, may only be operated in combination with a controlled drive, i.e. a frequency inverter.
“The reason for this is that a large number of asynchronous motors, especially pumps and fans, are still operated directly on the mains. The use of a converter increases the energy efficiency enormously depending on the application”, explains Tim Aufderheide, Application Engineer at KEB. “Only motors of class IE3 or higher may be operated directly on the mains”. New is that in the 2019 revised guideline now also frequency inverters must meet a minimum efficiency. In order to be able to evaluate this, the standard (EN 61800-9-2) describes limit values and methods to determine the energy efficiency of frequency inverters.
In the #TechTuesday webcast under the topic “Ecodesign and Frequency Inverters”, Aufderheide and Tobias Wenneker (Product Manager Drives) talked, among other things, about the questions why the Ecodesign Directive was introduced in the first place and, above all, who has to comply with it? A previous episode on “Ecodesign Directive and Motors” can also be found in the #TechTuesday archive.
