For all their energy savings and control benefits, when VFDs fail, they bring motor-driven industrial operations to a dead stop. To avoid such situations, savvy engineers ensure drive-system ...

When an application requires changes in motor speeds to meet its objectives, a variable frequency drive (VFD) is often the first thing that comes to mind. This is for good reason—VFDs are typically ...

This article presents a reference design for driving a vacuum fluorescent display (VFD) using the MAX15005 power-supply controller in a flyback topology. The design obtains multiple output voltages ...

Dublin, Feb. 09, 2021 (GLOBE NEWSWIRE) -- The "Global Variable Frequency Drive (VFD) Market by Type (AC, DC, Servo), End-users (Industrial, Infrastructure, Oil & Gas, Power Generation), Application ...

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 prime and immediately tangible target for saving energy using variable frequency drives (VFDs) is old mechanical systems, typically using centrifugal pumps and fans, that vary the flow of either ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...

This is the second half of a two-part article discussing principles and application of the AC induction motors that provide motive power for most of the equipment HVACR engineers specify. In March, we ...
