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 ...

When the U.S. Department of Energy (DOE) issues the final versions of it its long-awaited fan efficiency test and efficiency standards rules over the coming months, it will apply regulations to a ...

Often, an HVAC system is designed by the selection of individual components and not by a whole-system approach. This has become common practice for mechanical engineers, usually resulting in poor ...

This file type includes high resolution graphics and schematics when applicable. Determine if a VFD is right for your application. The primary function of a variable frequency drive is to vary the ...

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 ...

Ideal applications for VFD Series motor drive modules include 48VDC and 200–240VAC three-phase BLDC, induction, and SynRM motors used to power machinery ranging from fans, power tools, water pumps, ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...
