Re: 3-phase motors run on single phase.
Howdy Schematic.<br /><br />Hmmm. Theoretically it should work. <br /><br />I would give it a try with two paralleled caps like those used to start air conditioning compressors. Connect them in series with one winding. If you get reverse rotation, switch to another winding. I think they are typically 220 to 330 ufd and rated for 250 volts, min. Two of them would give you 440 to 660ufd and get closer to a 120degree phase shift.<br /><br />You could leave them in the circuit and get more torque or you could take them out with a centrifical switch, like so many induction motor appliances. <br /><br />You might have a problem with the management of counter EMF developed in the third phase winding. Whatever you do, don't short it out!<br /><br />If that doesn't work, we can cook up a gyrator with some triacs or SCRs.<br /><br />Good luck.
