Shaft Grounding — Fulfilling the Promise of Variable Frequency DrivesDownload Now
With the rising cost of energy, the use of variable frequency drives (VFDs) is growing at an increasing rate. By optimizing the frequency of a three-phase alternating-current (AC) induction motors voltage supply, a VFD controls the motors speed and torque while providing energy savings. And, these energy savings can be quite substantial 20% or more making VFDs a green solution as well as a wise money-saving investment.
However, in order to be truly green, a technology must be sustainable as well as energy efficient.
