Keeping up with the terminology surrounding the usage of variable frequency drives can be daunting. Maybe if there were one place where you could look up definitions of these ever-increasing terms, it ...

When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, ...

An interview with Southwire Company’s Steve Wetzel highlights how proper variable frequency drive (VFD) cable termination ...

A VFD reports a low-volts fault when the drive's dc link voltage drops below 62% of the nominal level for the high setting (480 Vac) and 50% of nominal for the low setting (400 Vac). The +10% and -15% ...

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 ...

Although much has been published on variable-frequency drives (VFDs), people continue to be confused by them. The intent of this article is to provide a basic overview of these devices by evaluating ...

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 P-Series line of variable frequency drives (VFDs) has been enhanced with a new redundant VFD unit. The Redundant Drive Panel (RDP) is designed to provide an economical HVAC motor control solution ...

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 ...
