When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...

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% ...

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 ...

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 ...

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 ...

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 ...
