@steve_chow

Good work. There are some things you have to know about but I am not the best guy to give you the most recent RV techniques. There is a member here named @ashtweth_nihilisti and in my book, he is the best one to comment on present RV. I have put a post in a new thread he just opened to refer him here.

His threads starts here;
http://www.overunity.com/index.php?topic=7055.msg164581#msg164581

Before doing any talking about power measurements, etc., 3-phase to single phase, his first question will most likely be, did you read a good part of the RV information that is already out there?

I will still be here but would hope that Ash can give you better information at this stage.

Regarding AC to DC, here is a photo of a big bridge rectifier I used to transfer the single phase AC output of a generator to the DC input of a DC drive motor via 24 x 12 volts batteries. You might need one but for three phase.

Here is a link that goes over phasing basics and 3-phase rectifiers if any help.

Geez, this is the first time I am doing a two-way thread referral. Well there is always a first time. lol

@wattsup

Thanks ..I will send mail  @ashtweth_nihilisti .

I do have three phase bridge rectifier unit (150 amp) which I designed for my other project....
but now  I need 10:1 transformer  to reduce the voltage 206 Volts AC  to ~ 20volts AC  then
I can run through bridge rectifier to get ~15 volts DC.

Do you know where I can buy 10:1 transformer .....

regards

Chow

Hi
I think you busy with Mylow HJ replication...
I did following test with RV setup-

Input - 120 volts 1.2 amps

Test 1-
Used three transformer   with alternator output-
transformer output (converted to AC to DC)- 16.5 volts DC 1.3 Amp/phase which means I connected three battery with three(L1,L2,L3) diff phase and all batteries are charging without any problem , running cool..
Test-2
Connect L1,L2,L3 direct to AC to DC converter..
output - 242 volts DC 1.3 amp without load...
alternator temperature- warm......
So far no sign of OU...
regards

Chow

Dam i forgot about this post please remind me in an EMAIL in future guys. Steve, please bring the description over to EVGRAY, we can cut and paste the solutions back here after that, but most of them are over at EVGRAY who will advise on your set up.
Please post and join here

thx wattsup.

Just a note for beginners, note that the principle of the RV is to create VARS (reactive power) and transform them into usable watts BY THE RV'S METHOD IN THE COMPILATIONS.
If you loading it down in another way  you will need to try other things, like step up up ratio's (belt 6-1 etc) frequency driving it (flywheel) etc. But its not intended to be OU this way.

Its very hard to tune BTW, but its been done twice, in fact ask these two guys what happened when they did it.

Hmmmm, just seeing something on a cam means nothing.  I can easily fool people doing that with my current set-up and show a 3:1 o/u....but it's not usable.  It's like the guy with the highly expensive d/c motor saying he did....not.  If one of these guys will talk to me on the phone that states they have accomplished a loop, it'll fire my POS back up and try their way. 

Just for the record as well.  I built the self powered water pump that I'd read on this site in February.   About $90 and 8 hours later another failed project.  The science looked good to me but I was not thinking in the terms of hydraulics as is needed, at least I now understand how to evaluate these types of machines.

Also, the guy shooting a stream of water onto a paddle will never work.  Yes, it will work shortly but the energy is simply stored in the water.....nothing else.

I know I sound negative, but it's disheartening to watch replication after replication of failed ideas only to find the so called inventor either lied or was simply wrong.

Just a passing thought, but if they really have a running looped rotoverter then why don't they place it on ebay?  That thing would easily sell in the thousands if not 10's of thousands of dollars.  It does not take two days and $500 to build one of these systems so he'd be making probably over $1k per day...sounds like good enough pay to me.

How long do you think it would take before the "boys" came around and shut down his little operation on ebay?

BTW looping an RV is dead easy anyone can do it. Just needs a bit of tuning thats all.  OU has always been here but most are too lazy to look and try it.

There is a whole lot of circuit sims going on over at EVGRAY now showing a loop, we are testing them also.

5.5 kW motor running on 4 W
« Reply #143 on: May 27, 2009, 10:17:57 AM »
You can call this „saving energy” when running a motor idle in rotoverter configuration.
A motor 5.5 kW at 50 Hz or 6.6 kW at 60 Hz (7.5 hp) runs on real power less than 4 W on one phase, so theoretically it can be run from a small battery.

To achieve such result the motor bearings have to be well cleaned and slightly lubricated, the fan and the gaskets have to be removed. This motor shaft stops turning ~ 2.5 minutes after the power is switched off.

This film shows the data: ~3 W on the watt meter (the active range is 100 W), 0,21A on the amp meter (left) and 20.14 V on the volt meter):

And here is the update, actually only the short film on youtube:
You may remember, this is an old experiment I did, trying to run 5.5 kW 3 phase, 400 V 1430 rpm motor on as little power as possible.

i looked at this years and years ago but was unable to try it out,and i still cant, from what i understood is once you hook up a load to this system........it stops,.......


.....has anyone tried this or know whats really going on once you hook up a load ?.

thanks in advance.

Peace.

rotoverter on 3.25 W
« Reply #147 on: June 07, 2011, 08:49:27 PM »
I tested shorting capacitors using the Hector's diode plug.
After that I switched off the thyristors and wanted to for curiosity, how little my 5,5 kW / 400 V, 50 Hz motor can draw and still turn the shaft at its nominal speed.
And the bearings were still with it's factory grease, not cleaned yet.

Watch the film, that I just uploaded:

Hello,

I am new to rotoverter and I am sadly not (practitioner engineer). I had a look at a lot of links (pdf-files, videos, the peswiki etc.) and a few questions about rotoverter.

1.) Which is "now" the most advanced rotoverter project? The last posting is one year old, what is the actual situation?
Would be very nice, if you can help me/us.
2.) Is it necessary to have to study over weeks or months, to get an idea, if it is working? Is there a consensus in the community  about rotoverter? Or do/work the most of you, on other  topics as on rotoverter? If, yes, why?

Thank you.

Welcome to OverUnity Twinkie.  I have studied into the Rotoverter.  It seems like the payback from having
to buy some HUGE 3 phase motors just to get some promised free energy doesn't seem worthwhile to most folks.
 
Most peple here would rather have something that generates electricity directly without
mechanical motors, bearings, pulleys, flywheels, pumps, chemicals, turbines, hydrogen, etc.
 
To see the ideal free electricity device (NO MOVING PARTS) click on the Link below.  But so
far, nobody has been able to duplicate it.  Nobody even knows where we can get a schematic.
