Shaft Grounding — Fulfilling the Promise of Variable Frequency Drives

Overview:

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 motor’s voltage supply, a VFD controls the motor’s 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.
