I know this is a stupid question - but I am having an impossible time finding the wiring for the rotoverter/3 phase motors. I have acquired some unused older GE 3 phase motors, but I cannot find anyplace showing which wire color off the motor is for what, so I am at a standstill.

Can anyone help me by just showing/telling which color wires are which on the 3 phase motors? I have got the capacitors for my variable bank and start up, but can't go farther without this simple (and probably stupid) problem being solved.

Thanks
Victorfolk, nevermind about the colors or the numbers of the wires. All you need is 3 wires that are already coming out of the windings.
Number those wires as 1,2,3  and start testing the motor, then one by one switch the wires around. You'll find that experementing like this you'll master the art of fine tuning your 3 phase AC motor.  It helps to have a clamp on amp meter or new watt meters that can be purchased for $20 . It will be fun to see that you can run 3 HP motor under 20 watts... Have fun man

Hi Mem ok you told Victor nevermind about wire colors but what Capacitors should one use then to 2nd and 3rd wires?
And for Europe running a motor 240v in normal mode what voltage should one give after modifiying this motor?.
Thanks.

<<guruji,
Take a look at this circuit here http://peswiki.com/index.php/Image:D2_rotoverter02.JPG the circuit was made to run with 120v to use this circuit with 240v probably you need to lower the capacitor values to half what says there. Like 17.5 uF is used for run cap. for your project use 5 or 8 uF ( my rugh guess here)

I bough a 20 HP, 3600 RPM motor that took me for a while to get this motor going, the problem I had my run capacitor value was too low!
But once I used the right value of capacior (can't remeber what it was now) this motor runs beatufly. Runs with 240v probably uses around 2 amp. just to idle, The motor is weigh aroun 250 lbs. Factory lable on the motor says this motor at 230v needs 44amp (just to run without doing any work).
 Yes it's true that motor runs with full speed but as soon as you put a load on the shaft slows and stops.

Be great if we can find the way to build a generator that with have no back emf or drag! Sort of using DePalmas generator.
Then you can produce all the energy you ever need!

Sometimes naivity is funny, sometimes not,
Look at http://video.google.com/videoplay?docid=-794876184702452555
Who measures "1000W light bulb" what it gives out in reality?
Nobody!

 congrats for 2nd place in applied mechanics california state 2008 science fair
hi.. just found this, some of you might find it interesting:

CALIFORNIA STATE SCIENCE FAIR - 2008 PROJECT SUMMARY
Name(s) Austin Adee; Alex Thomas
Project Number S0801
Project Title: Rotoverter

Abstract

Objectives/Goals
The objective of our project is to see if electricity can be generated more efficiently than onventional methods. We hypothesize that using two three-phase motors, in a setup a "Rotoverter" electric energy can be generated more efficiently than conventional methods.

Methods/Materials
Materials: A steel U beams, copper wire, capacitors, switches, power meters, two AC three phase squirrel cage motors, Plexiglas, transformers, full wave bridge rectifiers, an inverter, and epoxy are used in our experiment.

Methods: To build our setup; weld the steel U beam in a rectangular configuration; open the electric
motors, and clean the bearings of grease; reverse the casing of one of the two electric motors, and
assemble them back together; wire the motors so that one is an alternator and the other a motor; wire the switches in series to the capacitors, which are parallel to each other; and wire the capacitor banks to motor and alternator.

Results
We successfully found an alternative way to generate electric energy more efficiently than conventional means. In the process of doing this, we generated more reactive power than is consumed. Reactive power can be described as energy that does net value of no work. Achieving a greater amount of reactive power than true power is not a new concept and is accomplished very easily. What's different about the Rotoverter is that we can extract some of this power which is considered imposable by definition. We are not sure how the Rotoverter works, but only that it does produce large amounts of reactive energy that can be extracted on a small scale. There are two probable solutions around this; either get a resistive load to match our resonating output, which in our case would be a 4.5kw light bulb; or get an inductive load such as a transformer, that does not break the resonance of the alternator.

Conclusions/Discussion
As of this moment, we have only produced reactive power, but at a much greater amount than real power
consumed. We have not yet experimented with the two possible solutions mentioned before because of the
lack of materials. Further experimentation may reveal that the reactive power can be extracted.

from http://www.usc.edu/CSSF/Current/Projects/S0801.pdf

---
so here's another "yep, we got some reactive power running in our rotoverter circuit - and it should eventually be extracted" type thing.
what are your thoughts on this, please?

Guys, Who says rotoverter does'nt work? I did it tried myself. I used 2 Australian made 7.5 hp motors as prime mover and generator respectively and I got output 7 times the input of 200 watts. Better try it yourself to disprove Hector's discovery. Don't be an asshole arguing without doing it yourself. I am a mechanical engineer and I did it ran infront of some engineers here in the Philippines. People here are the "see it to believe it" type like you. I'm betting my balls on it!

was that 7 times output the "out of phase" virtual current (was it VAR that they called it?) that some have managed to get circulating inside the setup, or did you extract it - and with which extraction circuit, please?
i think theres certain people who doubt anything related to the rotoverter, who would really appreciate some details on this whole thing. its nice to see at least someone on overunity.com actually doing something related to the rotoverter. btw,there was a more active discussion going in the rotoverter thread over at http://energeticforum.com/renewable-energy/

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

http://uk.youtube.com/watch?v=RzO_lzgfoKM
"
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=nGGL7Hs0p5Y
this 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: http://www.panaceauniversity.org

also look through some of hsi circuit schematics either on the page he linked (geocities.com/koneheadx) or access them at

Hmm so anymore news about this? It seems like it's the most obvious case of free energy yet you don't hear a lot about it.

well, it appears that someone made a RV Water Pump. (from http://energeticforum.com/renewable-energy/1507-roto-verter-7.html)
--
"I just completed a test on my 3 PH old water pump motor to run in RV modes. Here is my video link:
http://www.youtube.com/watch?v=V3lfQSkaz4M" YouTube - RV water pump-1
--
"One more. This below is my test on RV modes water pump. I got better result now (only 100 mA draw current)."
http://www.youtube.com/watch?v=E46HOfENYEA YouTube - RV water pump-2
"built it based on Roto Verter documentation at panacea bocaf site."
"it is a 3 PH motor. This motor actually used as water pump motor with only have 0.17 HP at 220 VAC, 1.2 A, 50 Hz, 2850 RPM (specs) with 8 uF 450 VAC start capacitor.  I hope later I will able to built a 4 or 5 HP motor which could runs a 1-2 HP dinamo or alternator. It will be very usefull for our energy saving and alternative."

this system also works with sinlge phase motors as well so give it a try am mostly interested in feedback circuit neon .
if you read the sum of this post you have tesla's car figured out but type of motor may be inportant as not all induction motors are equal so keep this in mind as you discover what is happening be sure to list motor specs as it will be most helpful to everyone involved i have tried two motors and am on my third a three phase universal ge 5 hp with j winding class will have to change some configuration.
the single phase motors used varing start windings and were both ge motors with one being a continous duty and one intermittent coils of each were found to not be alike or giving rotoverter results on the continous duty motor so needed some reconfiguring run now at .5 amp and can still go lower to the voltage.
good luck to all in there attempts at conversion.

RV mode on 2 HP 3 PH AC induction motor
« Reply #118 on: January 08, 2009, 11:47:29 PM »
All,

I have next setup on induction motor in RV mode. Here below is the video link:

http://www.youtube.com/watch?v=Q_p3y1g83MI

But why it's a humming sound appear when start cap connected to motor, and the sound gone since it disconnected/switch off from the setup ? Is there something wrong on my setup ?

Hi All,

After a couple of days to do some business I made a test on RV mode to have resonance effect on 2nd motor as alternator. I have 3 PH 3 HP motor that I used as a prime mover driving the 2 HP 3 PH motor (act as alternator) via a belt.

I found the main thing on the system is speed/RPM. If I could get speed with lowest power input, I will get higher voltage on the alternator. And I'm sure we could control the output frequency thru this speed too. We tune the capacitor to have lowest power input on PM with the fastest we can get to get power output.

Yes, I got it. My first target is to sure the resonance work on the alternator and I got that. Next target is to tune the system with my capacitor available. We'll se..

Here is the video link:
