Overview

Variable-frequency drives (VFDs) are devices used to control the speed and torque of electric motors by varying the frequency and voltage of the power supplied. VFDs are commonly used in applications like HVAC systems, industrial machinery, and pumps where precise motor control improves efficiency and performance.

FAQ

What should I consider when buying a used variable-frequency drive?
