The VFD Panel (Variable Frequency Drive Panel) also known as VFD Control Panel are designed to control the speed of the electric motor and feed pump. They are widely used in drilling, pumping and other large machine applications like Conveyor and Compressor. These are designed to give sophisticated front appearance and spacious internal layout to facilitate easy preservation.
AC motor speed is controlled in two ways – either by controlling the voltage or frequency. Frequency controlling gives better control due to constant flux density than voltage control. This is where the working of VFD's comes to play. It is a power conversion device which converts the fixed voltage, fixed frequency of the input power to the variable voltage, the variable frequency output to control AC induction motors.
