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 ...

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 ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

Manufacturer's report courtesy of Pfannenberg Inc. Variable frequency drives are a hot topic. Advancements in VFD technology and reductions in price are driving rapid market adoption. Dramatic energy ...

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 ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

Variable speed drives (VFDs) can (and do) save energy in multiple ways. Of course, the degree of savings depends upon the application, the drive features, and how you have the drive set up. Generally, ...

When it comes to making decisions among various automation technologies to perform a task, the answer is rarely clear cut. Ultimately, the decision is often tied to the specifics of the application ...
