Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives

Saving energy is more than the right thing to do
Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.

For over 40 years, variable frequency drives (VFDs) have been a critical component of commercial and industrial systems’ efforts to improve energy efficiency. Today, their fundamental usage has remained the same, while technology has evolved and improved—yielding drives that are better able than ever to reduce energy consumption and improve reliability while extending equipment life.

On the whole, VFDs are designed to optimize energy use. How a VFD optimizes energy use differentiates the technology from various manufacturers.

Today, new algorithms are delivering significant energy savings and stability, and establishing a new level of efficiency for commercial buildings. A novel control algorithm for VFDs reduces the input power of an induction motor used to drive a variable torque load, like a fan or pump. The algorithm dynamically adjusts the motor’s operating point based on its load conditions, and providing power savings and improving energy efficiency.
