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.

When a VFD starts a motor, it initially applies a low frequency and voltage to the motor. The starting frequency is typically 2 Hz or less.

Most of the industrial applications require variable speeds at peak load conditions and constant speeds at normal operating conditions. Closed loop working of VFDs maintains the speed of the motor at a constant level, even in case of input and load disturbances.
