Many of these savings can be accomplished through the use of variable-frequency drives (VFD) (Figure 1). The world’s first mass-produced VFD was introduced in 1968. Computerization, the reduced cost ...

Variable frequency drives (or VFDs) are widely used throughout industry to provide adjustable speed control of ac motors. Although modern versions are relatively simple to install and operate ...

These variable-frequency drives (VFDs) accurately control the speed of standard AC induction or synchronous motors. With VFDs, speed control with full torque is achieved from 0 rpm through the maximum ...

As variable frequency drives (VFDs) are becoming the primary go-to solution for motor control, their capability is not something that can be matched. With every new generation comes better ...

Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a couple of typical scenarios commonly encountered ...
