As the cost of components and pumps becomes more affordable, variable speed pumps are being used to increase the efficiency and reliability of water distribution systems in multi-story buildings.

This generation of variable-speed pumps can internally sense how many valves are open or closed and adjust speed accordingly. Variable speed pumps have been around for years. As I mentioned in last ...

El Segundo, Calif.&#8212International Rectifier's IRMCF371 serves as the hub of a sensorless sinusoidal motor control platform that touts quieter operation and higher efficiency for variable-speed ...

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 ...

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 ...

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 ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

The GA800 variable speed drives handle applications ranging from simple fans and pumps to high-performance test dynamometers requiring precise regulation. They feature highly flexible network ...
