Why Variable-Speed Drives (VFDs)?

How VFDs reduce energy by matching load to speed (not just on/off or dampers).

Most pumps and fans don't need full output most of the time — yet without a drive, a motor only knows how to run flat-out. A variable-frequency drive (VFD) lets the motor slow down to match the actual demand, and because of one remarkable piece of physics, slowing down saves far more energy than intuition suggests.
