    120v VFD setup for 1-phase/3-phase 220v motor

    A device that converts alternating current with constant voltage and frequency into alternating current with variable voltage or frequency is called "variable frequency drive". VFD has the functions of voltage regulation, frequency modulation, voltage stabilization, speed regulation etc. VFD is generally used to control 3 phase AC motor in variable speeds. Now the three phase 220v-240v motor can run on single phase 120v power supply. ATO offers you 110v/120v input, 220v/230v/240v output VFDs. It can not only realize single phase input & output, but also convert single phase to three phase.

    Can a 3 phase motor run on single phase?

    If you want to connect a 3-phase motor to a single phase power supply, then you have several solutions:
    1) use a VFD with a single phase input and convert to 3-phase output, this is generally available for low power VFD (few horsepower).
    2) apply a specially wound transformer that also mimic a 3-phase system from a single phase power supply. Expect difficulties to source and high price.
    3) calculate a capacitor that will be connected between the remaining phases, such to apply it a phase shift and to mimic a 3-phase system.
