Parker Hannifin has sponsored this post. Electric motors are the dominant form of motive power on Earth for a reason: they’re efficient, scalable and versatile. That versatility has driven the ...

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 turning, and decreasing that frequency to ...

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 ...

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 ...

In this episode, we connect with Steve Wetzel, a member of IEEE and principal applications engineer with Southwire Company, one of North America's largest wire and cable manufacturers and the sponsor ...

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 ...

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 ...

The Powermatic 2014B Lathe from Powermatic Tools, JPW Ind. has a heavy-duty, cast-iron construction across the bed, legs, headstock and tailstock, and an adjustable leg stand design that further ...

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 ...

The variable frequency drive (VFD) cable business has become a very large market for cable manufactures in the last 20 years. In the past, standard AC motors had the complexity of a squirrel cage ...

A 12-pulse VFD has phase shift transformers ahead of 6-pulse VFD to cancel the harmonics reflected back to the source. The phase shift transformers can be tuned to reduce harmonic distortion to less ...
