Working Mechanism
- Fuji Electric variable frequency drives operate on a fundamental principle of adjusting the frequency and voltage supplied to an electric motor, thus controlling its speed and torque output.
- It converts fixed-frequency alternating current (AC) power from the mains into direct current (DC). The DC power is then inverted back into AC with variable frequency and voltage, allowing for precise control of the motor's rotational speed.
- This flexibility in speed regulation makes VFDs suitable for diverse applications, optimising energy consumption and enabling efficient operation.
