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.

3hp VFD question answering

Do we still need to debate VFDs when used on single phase input power like we did with the older VFDs or have you done something like beefing up the input diodes and caps so they will be able to output the same power as on 3 Ph?

ATO Responded

For our 1-phase To 3-phase drive, no need to oversize, we care about that in design, just consider 10% margine above rated output current referred at each model seen at our web site.

3hp VFD output voltage

I am trying to drive a custom solenoid at variable frequency. Curious to know if the output voltage of GK3000-SP1S1-2d2 is variable.

ATO Responded

We recommend to use the drive with motors only. And yes, the output voltage is variable.

What's wrong with my 3hp VFD?

I got a problem with your drive, with a 3 phases motor the output voltage drop to 150 and without load it has 220. What's wrong?

ATO Responded

The problem you mentioned is probably caused by the over load current driven by the motor is huge, and then the input voltage and bus bar voltage to be low. You can try to set F0-10=60, F0-12=60, F0-17=10, F0-18=10, then rerun the VFD and test again. When the VFD is running, you can switch the shift key >>U0-03 & U0-04, to see the voltage and current output from the VFD real-time. If the VFD cannot working properly, you may need to replace a larger capacity VFD.
