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 ...

More and more often, variable frequency drives (VFDs) are used for control of fans and compressors in HVACR systems. The benefits are well documented and industry acceptance is such that most electric ...

Honeywell and Danfoss are partnering to integrate variable frequency drive (VFD) technology with Honeywell's Experion Process Knowledge System platform to streamline motor control, reduce energy ...

Experts examine the procedure of commissioning, running it up and checking it out, medium-voltage VFDs rated 250 hp (186.4 kW) and larger at a minimum 2.3 kV voltage level. Equipment commissioning is ...

In today’s world, motors are ubiquitous, powering everything from household appliances to industrial machinery. The importance of optimizing motor control for energy efficiency cannot be overstated, ...

It’s been a while that I want to write a post to discuss about the real impact of the electronic/semiconductor device selection on the energy consumption of electric motor-driven systems. It seems ...
