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.
