Delta Electronics has announced a new generation of VSDs (variable-speed drives) designed for applications such as pumps, ...

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 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 ...

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 ...

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 ...

Dart Controls’ 700 series Commutrol DC Brushless Drives are a compact, economical, and energy efficient alternative in brushless dc motor control. They’re suitable where high speed or quiet operation ...

VFDs can produce high-frequency electrical noise, harmonic current, and additional heat during normal operation. Cable ...

For example, consider the United States, where the incoming line frequency is usually 60 Hz at 120 V. If an engineer has an AC motor with two poles (a pole pair motor), then the motor's synchronous ...

Soft starting techniques for induction motor drives encompass a range of methods designed to limit inrush current, reduce mechanical stress, and improve power quality during motor start‐up.
