Running a Three-Phase Motor and Single-Phase Supply

Hello Goat80,

There was a recent answer on this forum to this exact question.

Please have a look here:

That will save me typing it out, all over again.

Note that Topic asked re "two phase input", but the Topic Poster really meant single phase.

If you still need advice after reading that earlier Topic, please reply here, thank you....

Yes you can run three phase from a single. My uncle use to in the hills of Alabama when he couldint get three phase power but three phase motors was cheeper.

you must have a free standing three phase motor and a capacitor. wire your single phase 220 into two leads of your free standing motor and your cap in line with a switch from one of those leads to the remainning lead on the motor. when you turn on the 220 you must have the switch in line with the cap on and you might have to spin the motor shaft to get it to choose a direction and after it starts you must turn off the switch (very important). You will need three leads comming off the motor that is setting there running going to a three phase disconect and your three phase 220 will be there.

However. there is single phase to three phase coverters on the market now days all assembled inside a box with directions. Takes the danger of exploding capacitors out of the picture.

On the web it is the Ronk co. Otherwise follow the instructions above. First spin the converter then disengage the driver that caoused it to spin and turn on the power to convert.
