You can divide the world of electronic motor drives, which control the speed, torque, direction, and resulting horsepower of a motor, into two categories: ac and dc. An ac drive controls ac induction ...

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 ...

Adjustable speed drives (ASDs) or variable speed drives (VSDs), also called variable frequency drives (VFDs), typically control a motor's velocity or torque output. Most adjustable frequency drives ...

Alex Lidow and Marco Palma look at the value of high-frequency motor drives, their advantages and the capabilities of GaN technology, which make them suitable for today’s demanding applications.

Adjustable or variable frequency drives AFDs or VFDs use rectifiers to convert ac powerline electricity into direct current. Then inductor-capacitor filters Adjustable or variable frequency drives — ...
