Variable frequency drives (VFD) are reliable electronic devices that control three-phase electric motor speed. They are used in building automation, industrial, pumping, agricultural, irrigation, and water/wastewater applications to control the speed of fans and pumps in various systems. The payback period for installing drives is usually less than three years and can be less than a year.
The Yaskawa $avings Predictor App estimates energy savings when using a variable frequency drive instead of conventional volume control methods. Detailed estimation results can be e-mailed directly from the application.
