For many retrofit projects, the use of a VFD seems like a “no brainer.” Drives are now cheaper and more reliable than ever, and the benefits of efficient control of motors can’t be beat. Still, there ...

To coordinate more than one aspect of a process, variable-speed drives must be able to communicate with many devices. To illustrate, on a bottle labeling system, the drive must be able to precisely ...

Sustainability is one of the greatest priorities across all industries, and many organizations have set ambitious net-zero goals to minimize their environmental impact. This has led sustainability ...

Compressed air is a vital utility to most commercial and industrial operations. It runs essential tools and machinery, provides power to material-handling systems, and clean air to processes. Yet ...

Prior to the advent of the adjustable-speed drive (ASD), the polyphase induction motor operated as a constant-speed motor. Figure 1 shows the well-known torque and current curves versus speed for the ...

Well, transmissions are designed to let a drive system – be that an engine, an electric motor or a set of cyclists' legs turning a crank – operate at its optimal speed for efficient torque delivery, ...
