VFD Panels are designed to control the speed and torque of electric motors by varing input frequency and voltage to motors. VFD Panels are used as energy saving devices as they adjust motor speed under no load conditions or as required by the process. Such energy cost savings are especially pronounced in variable torque centrifugal fan and pump applications where there is large power reduction for a relatively small reduction in speed. We design and manufacture a diverse range of VFD panels for variad applications (closed-loop and open-loop applications).

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.
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 VFDs 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.
Energy Saving
More than 65% of the power is consumed by electric motors in industries. Both magnitude and frequency control technique to vary the speed consumes less power when variable speed is required by the motor. So a great amount of energy is conserved by these VFD’s.
Closed Loop Controlling
VFD allows accurate positioning of the motor speed by continuously comparing with reference speed even at changes in the loading conditions and input disturbances like voltage fluctuations.
