What Is a VFD and Why Every Motor-Driven System Needs One A VFD (variable frequency drive) is an electronic controller that adjusts an AC motor's speed and torque by varying the frequency and voltage of its power supply. Instead of running a motor flat-out and throttling output mechanically with valves, dampers, or gearboxes, a VFD ramps the motor itself up or down — typically cutting energy use by 20% to 50% on variable-load applications like pumps and fans. If you're asking what is a VFD and whether your facility actually...
