Energy Saving with Variable Frequency Drives
Energy Saving with Variable Frequency Drives
One of the big advantages of using variable frequency drives is energy saving. Energy savings can also be made by careful motor selection; energy costs over the life of a motor are fifty or a hundred times the cost of the motor, so choosing a high efficiency motor (IE3 or better, IE4) makes sense. EU regulations now mean a new IE2 motor must be operated with a variable frequency drive in any case.

We’ve already seen how closed loop control can be used in many applications to regulate temperature, pressure or flow rate. Most variable frequency drives have a built in closed loop control that can be used for this any many other applications.
