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 ...

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 ...

Variable-pitch drives are the simplest of all mechanical adjustable-speed mechanisms. Most of these drives use rubber belts. However, chain types are unmatched in regard to its particular strong ...

Imagine an easy-to-install industrial technology that reduces energy consumption, eliminates mechanical vibrations and electronic harmonics, relaxes alignment tolerances and cuts maintenance needs.

In May 2015, Danfoss, a leading manufacturer of high-efficiency electronic and mechanical components and controls for air-conditioning, heating, refrigeration, industrial, and water systems, finalized ...

The 15 series enclosed Digital Speed Controller from Dart Controls is available in open or closed chassis styles and NEMA 1 ...

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 ...

When selecting the most efficient and cost-effective variable frequency drive (VFD), it’s essential to understand the specific considerations involved in your commercial venture. No two industrial ...

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 ...

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 ...
