Variable speed motor controllers regulate the speed and/or torque of asynchronous motors. Depending on the application, there are controllers from a few hundred Watts up to several hundred Kilowatts.

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 ...

Wind Engineering, Vol. 45, No. 5 (October 2021), pp. 1206-1221 (16 pages) In this paper, a theory and practice-based research is conducted using real data, in order to increase the efficiency of a ...

Figure 1. The chart shows energy savings achieved by Refrigeration Service Co. with use of a variable-speed controller. EDITOR’S NOTE: This material was prepared by Heatcraft Worldwide Refrigeration.

First note - I am a completely new to water cooling, this is the first build I've done. With GPU prices the way they are, I decided to try for an overclock vs a new GPU. Things are working well, and I ...

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, ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

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 ...
