Tighter speed regulation (typically ±0.05%) is often the benefit of an encoder-based variable-speed drive, but costs more up front. Lower speed regulation (typically -3% to -5%), which is offered by ...

Compressed air is a vital utility to most commercial and industrial operations. It runs essential tools and machinery, provides power to material-handling systems, and clean air to processes. Yet ...

For many retrofit projects, the use of a VFD seems like a “no brainer.” Drives are now cheaper and more reliable than ever, and the benefits of efficient control of motors can’t be beat. Still, there ...

Variable frequency drives (VFDs), also known as variable speed drives (VSDs), are used to modulate the speed of motors in various applications, from hydronic water pumping to VAV fan units to vacuum ...

As a hybrid technology that combines mechanical and electrical systems, electrohydraulic variable speed drives allow for motor speed adjustments to conserve energy and provide precise control over ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...
