What is V.F.D and why it is been used?

Question

Accepted Answer

V.F.D stands for Variable Frequency Drive and it is used to control the speed of an electric motor.

V.F.D is an electronic device that converts fixed frequency and voltage input to a variable frequency and voltage output.
It is commonly used in industrial applications to control the speed of motors, pumps, fans, and other equipment.
By adjusting the frequency and voltage, V.F.D allows for precise control of motor speed, resulting in energy savings and improved performance.
For example, in HVAC systems, V.F.Ds are used to vary the speed of air handling units based on the cooling or heating demand, leading to energy efficiency.
V.F.Ds also provide soft-start and soft-stop functions, reducing mechanical stress on the motor and extending its lifespan.
