Are you ready? The more stringent European Ecodesign Directive requirements for motors have come into force in 2015.
Class IE3 is now mandatory for a huge range of motors. As an alternative, class IE2 motors plus frequency converters can be used. Learn more about the new requirements for energy efficiency and what they mean in practice.
Danfoss Drives experts are on hand to explain the new IE classes for frequency converters and also for frequency converter + motor combinations. Naturally, Danfoss VLT drives already meet the highest efficiency class requirement for frequency converters: IE2 – even despite their built-in EMC filters!
When it comes to systems, we are pleased to show how easy it is to determine part load losses and IES class for your motor+VSD combination – including when the components come from different suppliers. Coming soon is the new VLT ecoSmart, an online energy efficiency tool for easy calculation of part load loss data which calculates IE and IES classes for a VLT drive combined with a motor of your choice.
A wide range of high-efficiency motor technologies are available to fulfil the Ecodesign motor requirements. The choice can be difficult. Depending on motor technology and IE class it is important to be aware that a replacement motor can differ from its predecessor on a variety of factors; ranging from motor dimensions to start/acceleration/nominal torques and performance at the VSD. Be prepared to consider all the issues.
The good news is that one Danfoss VLT drive can serve all standard motor types, giving you the freedom to choose the best motor for your application.
