A three-phase motor is more efficient than a single-phase motor because of the peculiarities of alternating current AC. Electrical power, you may recall, is the voltage level multiplied by current flow. A three-phase motor may be set up in one of two configurations: a Y-type often written "wye," as it's pronounced or a delta-type. Also, these motors have either six or nine leads. With a six-lead set-up, you cannot choose whether you get a high-voltage or low-voltage system, but with a nine-lead set-up, you can select either one, using either configuration. This offers a total of four wiring possibilities.

Three Phase Motor Power & Control Wiring Diagrams
I have been making inquiries as to how to power this motor from a V single phase supply, and I would welcome any advice on the options that I believe I have. I know just enough about this subject to be dangerous. I will be using a qualified electrician. Any help would be gratefully appreciated.
