A variable frequency drive is a device used in a drive system consisting of the following three main sub systems.
Variable frequency drive motor speed controller.

Ac motor main drive controller assembly and drive operator interface.
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.
A variable frequency drive vfd also known as ac variable speed drive ac variable frequency drive vfd inverter or variable voltage variable frequency drive is a type of motor controller that drives an electric motor by varying the frequency and voltage of its power supply.
A variable frequency drive vfd is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor.

Where process conditions demand adjustment of flow from a pump or fan varying the speed of the drive may save energy compared with other techniques for flow control.
In addition the frequency can be adjusted outside the motor and then supplied to the motor so that the motor s rotation speed can be freely controlled.
Vfd control also has the capacity to control ramp up and ramp down of the motor during start or stop respectively.
Other names for a vfd are variable speed drive adjustable speed drive adjustable frequency drive ac drive microdrive and inverter.
Motor drive or simply known as drive describes equipment used to control the speed of machinery many industrial processes such as assembly lines must operate at different speeds for different products.
