What is VFD?

VFD stands for variable frequency drive. The VFD has two main purposes: to control the output frequency and to convert incoming single phase power to a three phase power. Here’s a quick breakdown on how these two processes work.

Controlling the Incoming Electric Frequency

For well pumps to accelerate and decelerate during a cycle, they depend on incoming electric frequency; 60hz. VFD systems sequentially control the motor output frequency, increasing acceleration time and reducing water pressure surges. This process causes a gradual ramping and extends the life of the controlled equipment, like the motor and distribution piping.

Incoming Single Phase Power Conversion

Properly sized VFDs can operate three phase motors with the incoming single phase power. This method converts the single phase into a three phase, allowing the use of more plentiful, more efficient and less expensive three phase motors.
