Also known as AC drives, variable frequency drives (VFD) are essentially controllers capable of driving electric motors, something accomplished by varying the voltage and frequency that goes into an electric motor.
AC Motor of Variable Frequency Drives
A variable frequency drive system uses an AC electric motor. Typically, this is a three-phase induction motor although a single-phase motor is also used on occasion. The benefit of a three-phase induction motor is that it works for most purposes and typically, it is the more cost-efficient solution. Keep in mind that when induction motors experience increased voltage stresses supplied by variable frequency drives, there has to be a design in place for definite-purpose inverter-fed duty.
Benefit of Energy Saving
A number of different load applications for a fixed speed motor supplied directly from AC line power save energy when operated with a variable frequency drive and at variable speeds.Original Source...
