A variable-frequency drive is a device used in a drive system consisting of the following three main sub-systems: AC motor, main drive controller assembly, and drive/operator interface.: 210–211 AC motor. The AC electric motor used in a VFD system is usually a three-phase induction motor.Some types of single-phase motors or synchronous motors can be advantageous in some situations, but
When the motor operates in one of these two modes, a regenerative drive can take the electrical energy generated by the motor and feed it back to the AC power source or to a common bus that supplies two or more drives. A common bus provides additional energy savings in that the power is only converted from AC to DC one time.

The motor manufacturers widely agree that energy efficiency, whether mandated by the Department of Energy (DOE) or by the market itself, will continue to influence motor and drive technologies. Efficiency is taking over; the push for green applications and the ability to lower power bills is driving these trends.
The drive also regulates the output voltage in proportion to the output frequency to provide a relatively constant ratio of voltage to frequency (V/Hz), as required by the characteristics of the AC motor to produce adequate torque. The first step in this process is to convert the AC supply voltage into DC by the use of a rectifier.
