    Tips: Running a 3-phase motor from single phase supply

    If you want to connect a 3-phase motor to a single phase power supply, then you have several solutions:

    • Professional: use a VFD with single phase input and convert to 3-phase output, this is generally available for low power VFD (few horsepower).
    • Professional: 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.
    • DIY: 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.

     

    How to run a three phase or single phase motor with ATO VFD on 120V power supply. Take a 2 hp, single phase 120V input, single phase or three phase 220V output variable frequency drive as an example. It shows you how to wire, set parameters, commissioning VFD, run motors, etc.
