Practically VFD helps to save enery in Variable torque
loads only like Fan , pump. With affinity laws Power
proportinal to cube of speed, so if speed is reduced you
will get energy saving by using this law.
For constant torque application , if your process speed is
not full RPM but less than that say 30 Hz , then energy
saving will be there by using VFD, as you are not required
to run the motor at full speed.
