VfD. Variable frequency drives are used to control the speed of induction motors which is the driving force for 90% of the pumps in Industrial application. simply saying the are used to control the flow as per the requirements. the flow may be water, air or gas. A motor running at 50% of full speed capacity has a motor torque of 25% of full speed. In
addition, electricity required to operate the motor at 50% of full speed is 12.5% of the amount
of electricity required if the motor was running at 100% full speed capacity. Thus, reducing
motor speed can significantly reduce the electrical energy consumptio
