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 ...

A variable frequency driven (VFD) is a type of motor that controls the levels of frequency and voltage that alter the speed of an electric motor. The drive alters torque and motor speed and can be ...

As the march continues to make motor efficiency nearly 99%, the way motors are used and applied can make a big difference in the overall sustainability picture of any plant.

Should you specify an “inverter duty,” “inverter ready,” “inverter rated,” or a “VFD compatible” motor for your fans and pumps in HVAC applications? Is there a difference in these terms? Don’t answer ...

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

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 ...

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 ...

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, ...

Jim Alt explains Nord Gear's new IE5 motor and variable frequency drive. These IE5 motors operate at high efficiency even at reduced speeds and with reduced loads. In this video, Alt explains the ...

When selecting the most efficient and cost-effective variable frequency drive (VFD), it’s essential to understand the specific considerations involved in your commercial venture. No two industrial ...

When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...

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 ...
