Within a certain period of time, the Ecodesign Regulation requires that newly launched motors must meet a corresponding IE class. That makes sense, because drives that run continuously (even in one shift) save a lot of energy with better efficiency.

Repairing old drives is therefore often pointless, but knowledge of the systems and operation is required to select a suitable replacement. Many drives are oversized, so a 1:1 power swap is only partially successful.

We show the various solutions here and will supplement and expand the texts and links over the next few years in order to offer a manufacturer-independent overview and a pre-selection.
