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 ...

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% ...

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 ...

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 ...

Variable-speed options are abundant in HVAC and their impact has been felt industry-wide. Contractors and manufacturers alike have taken to these single- and two-stage alternatives as ways to enhance ...

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 ...

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 ...
