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 ...

It's easy to understand how variable-speed motor drives benefit pumps and blowers from the energy curves that depict their performance. It is interesting to look at figures from the Energy Information ...

The A1000 variable-speed drive is compatible with interior and surface permanent-magnet motors for efficient and precise control, producing up to 200% torque with or without feedback. The A1000 ...

The most reliable means for changing shaft speed remains a mechanical variable-speed transmission. The most reliable means for changing shaft speed remains a mechanical variable-speed transmission.

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

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 ...

Selecting the right VFD can improve energy efficiency and swell profits. However, industry leaders are tasked with conducting some due diligence about these units. When selecting the most efficient ...

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 ...

A new solar-powered variable speed drive (VSD) model compatible with a wide range of water pumps has recently been launched. The Altivar solar ATV320 is Schneider Electric’s replacement offer for the ...

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 ...
