WEBSep 8, 2021 · The VFD will not change the amount of work done, so the energy consumed will be the same (minus a few percent losses in the VFD itself). Again, there may be other very valid reasons to use VFD control on rolling mills and it is done all the time, but "energy savings" is not one of those reasons.
WEBVariable speed drives precisely modulate the motor torque and speed in these variable torque appliions. This precise control aligns the motor's output with the exact load requirements, thereby enhancing energy conservation. To illustrate, if a fan's speed reduces by half, the torque required reduces to a quarter.
