A variable frequency drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage of its power supply. The VFD also has the capacity to control ramp-up and ramp-down of the motor during start or stop, respectively. If you currently have single phase power, using a VFD gives the option to purchase a three phase motor which is considerably less cost than a single phase motor.

• Converts single phase power to three phase power
• Takes the place of a manual or magnetic starter for the pump
• Improves the efficiency of the motor and reduces power use
• Slows motor start-up, preventing surges and prolonging motor life
• Provides overload protection for the motor
