Other considerations — such as the environment in which the variable-speed drive and motor are to be placed — are also important. Philippe/Leeson: With ongoing cost pressures and limited design cycle ...

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 ...

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 ...

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 ...

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 ...

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.

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 ...

AC induction motors are widely used in industrial applications due to their reliability and low maintenance needs. Comprised of a stator and rotor, these motors convert electrical energy into ...

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 ...
