Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

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 ...

To coordinate more than one aspect of a process, variable-speed drives must be able to communicate with many devices. To illustrate, on a bottle labeling system, the drive must be able to precisely ...

AC Kinetics announced that it is “now negotiating with several drive makers who are potential licensees,” says Dr. Neil Singer, president, AC Kinetics, Inc., an advanced engineering solution provider ...

When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, ...

Crailsheim, Germany/York, PA (May 19, 2017) – Voith introduces the first member of a new product family in the field of speed control for compressors and pumps: the VECO-Drive. It is an electric ...

The medium-voltage variable-speed drive (VSD) for Model YK centrifugal chillers is an addition to the York® OptiSpeed™ VSD line. The drive enables building owners to reduce chiller energy costs as ...

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

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 ...

What is a variable frequency drive? Heating, ventilation, and air conditioning systems' air supply used to be constant volume into a space. Now a variable air volume control is being used to provide ...
