Delta- Variable-frequency drive

Variable-frequency drive: VFD stands for a Variable Frequency Drive. It is an electronic controller that adjusts the speed and power of an alternating current (AC) electric motor by changing the frequency and voltage of the electricity sent to it. [1]

How a VFD Works

• Changes input AC power into direct current (DC).

• Cleans the power using internal capacitors.

• Converts DC back into an adjustable AC waveform at a chosen frequency. [1, 2]

Common Uses

• Pumps and Fans: Slows flow rates to match real-time demand instead of running at full blast.

• HVAC Systems: Controls air handlers and compressors efficiently.

• Conveyor Belts: Manages smooth start and stop speeds. [1, 2, 3, 4]

Main Benefits

• Saves electrical energy.

• Reduces mechanical wear on parts.

• Prevents high power surges during startup. [1, 2, 3, 4]
