hi, this is something that koneheadx created: and the video descriptions:

This a step by step "hands-on" AC motor rotovertor conversion demonstration.
I eventually got this motor to run at 180 milliamps at 120Vac with no load on shaft with a 9uf run cap.
IN NUTSHELL:
1) Hook 3ph AC motor up to its HV 460V circuit shown on its label. (they usually use the 460V circuit with these 3ph type of AC motors in heavy industry and factories)
2) Connect AC power feed to only 2 of the 3phases, so that the AC power feed lines connect to line 1 and line 2 coming from the motor.
3) Connect run caps and start caps between line 2 and line 3 coming from the motor..
Note: Line 2 coming from motor shares a connection with one of the power-feed lines, and also one side of the AC run and start caps.
4) Adjsut run cap UF value to get lowest draw first at idle, and also when the shaft turns a load too.
For beginners, run the rotovertor simply on single phase 120VAC grid power (or 240V if that is what you have in your country)
Later on, run these on a DC to AC INVERTOR! Now you will then be running this motor on batteries - golf cart batteries are the norm, as they are a type of battery that can be discharged and charged everyday for 5years before they go bad - while regular car batteries can only do a few dozen discharge-charge cycles before they are no good.
For very advanced work with a rotovertor motor, use pulse width, voltage and freqeuncy adjsutment so you can really nail a super effecient rpm, voltage and power level for the particular load the motor is turning.
With these three modificationss to the motor (actually inside the invertor running it), you will most probably be able to acheive a self-running unit if you also have a very effecient no-lug type of generator on the shaft too.
go to my site:
http://www.geocities.com/koneheadx/look at link #16 for a rotovertor spinning a Bill Muller design of dynamo/generator
Also look at "circuit diagrams" link on my site too for the basic rotovertor circuit and some more advanced ones, which can make it so you can charge battery stacks at same time you run motor. "
http://uk.youtube.com/watch?v=nGGL7Hs0p5Ythis is the 2nd half of the rotovertor demo.
This particular 3450rpm marathon-brand 3ph 2hp AC motor shown in the video I eventually got to run on .18amps (180milliamps) at 120Vac with no load on shaft, using a 9uf run cap.
The rotovertor is a discovery of Hector Torres and has been replicated and tested by hundreds of people since it was introduced publically around 8 years ago by Hector.
This sort of motor has the ability to actually "run itself" if you spin a super effecient generator, and also pull out power not only from the generator, but also what the AC motor itself in rotovertor mode makes in additional power from its third "virtual" phase - this phase works more or less like a "rotary transformer"
Study the rotovertor circuit and you will see that the third phase does not draw electricity, but in fact makes AC power itself that can be extracted.
Look on my geocities site for the rotovertor circuit in "circuit diagrams" link - also look at the circuit there in that link that uses a 2nd trigger-transformer to pulse-out power from that 3rd virtual phase at the motor's sinewave peaks to charge 2nd battery stacks so there is "no reflection" to the input power to the motor itself. This can also be done using a strobe-light light sensor trigger circuit too.
my site:
http://www.geocities.com/koneheadx/Also look at link #16 which shows a 5hp 1850rpm rotovertor AC motor spinning a Bill Muller design type of dynamo/generator.
This generator should have its power-out pulsed out at the peaks of the sinewave that the coils prodduce to eliminate "lug" to the motor as it spins the generator.
Also look up lots of good rotovertor information at this site:
