Variable speed control of a compressor motor significantly reduces both the peak and average energy consumption. However, since the standards for air conditioners require a reduction in the seasonal ...

Geothermal heat pumps (GHPs) have been around for a long time, but recent technological advances have propelled these systems into a new sphere of efficiency and comfort, said Doug Dougherty, ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

Variable Speed Limit (VSL) control represents a dynamic approach to managing roadway traffic, allowing for real-time adjustments to speed limits based on prevailing traffic conditions, safety ...

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 ...

Motors are driving demand for electricity, accounting for about half of the electricity we consume, according to the Electric Power Research Institute (EPRI). Many of these motors are found throughout ...

Adjustable speed drives (ASDs) or variable speed drives (VSDs), also called variable frequency drives (VFDs), typically control a motor's velocity or torque output. Most adjustable frequency drives ...

A1000 variable speed drive has a calculated design life twice as long as previous generations. Compatibility with interior and surface permanent magnet motors produces up to 200 percent torque with or ...

Applications requiring variable speed control, precision performance with low torque ripple, and high power in a compact, 1.73'' in diameter package are said to represent the primary market for NT ...

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 ...
