A Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. These devices, also known as ...

Variable frequency drives (VFDs) have become omnipresent in the building automation world. This proliferation of VFD’s is due to two main factors. First, when properly applied to centrifugal fans and ...

The growth of advanced computing power embedded in a growing number of devices is changing the face of automation, and variable frequency drives (VFDs) are a big part of this trend. Capable of ...

There are well-known benefits of using variable-frequency drives (VFDs) to reduce energy consumed by induction motors. Federal, state and local agencies in the U.S. now all give incentives for ...

OEMs and hobbyists benefit from technology’s trickle-down effect. Figure 1. Many industrial applications and small machines with a motor and limited I/O requirements can benefit from using AC VFDs with ...

Increasingly common, variable frequency drives (VFDs) are used to control motor speed — elevating the frequency of power pulses/sec fed to motors for faster turning, and decreasing that frequency to ...

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, VFDs ...

Beyond the wheel, the most important mechanical equipment serving humanity is the centrifugal pump. Centrifugal pumps make modern quality of life possible. Turn on a faucet and a centrifugal turbine ...
