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 ...

Over 50% of Earth’s total electricity consumption is used for operating motors and motor systems. HVAC contractors and technicians encounter motors in a variety of different applications, and aspects ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...

As a hybrid technology that combines mechanical and electrical systems, electrohydraulic variable speed drives allow for motor speed adjustments to conserve energy and provide precise control over ...

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 ...

The GHS VSD⁺ 350 - 900 series of intelligent vacuum solutions from Atlas Copco Compressors LLC is available with variable ...

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 ...

Boosting energy efficiency in hazardous areas is critical for operators seeking to reduce their operating costs while also ...

This short video from [ProShorts 101] shows us how to build a variable speed disc sander from not much more than an old hard drive. We feel that as far as hacks go this one ticks all the boxes. It is ...

Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating ...

The asynchronous electric motor, also referred to as an AC induction motor, is the most common type of commercial and industrial AC motor. Its invention dates back to the 1800s and the likes of ...
