A way to operate a motor at high impedances with a lower reflective power loss at idle mode... Allegedly also an overunity generator


Thought it would be nice to have at least 1 way of making electricity with all these projects here. So, after a few years at the EVGRAY group, wanted to post this at instructables. The idea it to use 2 electromotors to create electricity. The Prime mover, tuned to use a low Amp, and the mechanical work for the "alternator". Many files and information bits can be found online. But let me give you the basic idea of it.

Step 1:


The Roto Verter (RV) is originally the intellectual property of Hector D Perez Torres. Hector has publicly released information on the RV makinng it open source.The following RV method plus any additional open source circuits mentioned in the compilations on this page all fall under a statutory public copyright (other rights apply). The RV is a scientific discovery and is covered by the publication statutory copyrights for 75 years. For engineers wishing to replicate and work with the Roto verter technology, additional technical support can be found from these forums:

EVGRAY yahoo energy group ... RV replication yahoo energy group ... Cavetronics Informatics ... Over unity forum RV section ... The Panacea Farm Conversion - The Roto Verter Segment

The RV is an alternative energy device which is currently being utilized by open source engineers around the world in energy saving applications, and to transform and understand ZPE when configured in looped (self running mode) mode...When run in RV mode, these Baldor motors are the most efficient 1 HP electric motors in the world...

The following presentation on the RV will be divided into two separate sections. The first will explain the RV in the role of ZPE research, the second will describe the RV as an energy savings application.

Background - Hector has explained to us that in order to acheive the extraction of ZPE (zero point energy) and to be able to self run the RV, a prior understanding and experience from using the RV in an energy saving power management application is vital.

The energy saving RV configuration proves that currently 1HP (horse power) electric motors waste energy by their inefficient configuration and that as a result, the ability to engineer a ZPE transformation is thus out of reach. The RV is an R & D tool designed to work with those issues in power management and to find solutions and applications for ZPE engineering.

Technically the RV is explained by the Roto-conversion: A Way to operate a motor at Hi impedances with a lower reflective power loss at idle mode. Working similar to a POWER transformer but on Electrical to mechanical conversion.

djsfantasi says: I read this Instructable with great interest. The poster has shown great skill in his presentation of the subject. One of the best examples of a huckster I have ever read. The vague and unsupported references to science, little proof crying that more money and support is required for research, obvious disregard for physics, blah, blah.

While over unity forums still exist, other technical forums ban the discussion of the topic. I am reminded of Harry Houdini's crusade of mediums and their responses.

leddewis says: what a bunch self gratifying drivel.! i speak not of the wonderess r/v but of this long winded pat on the back for panacea-bocaf and yourself this is not a soap box this is a place to instruct or be instrucked not preached at i did not see one word on how, except for that blurb at the start, unlike this commercial that spewed its praises..

Zettu : Yes, Please someone remove this Advertisement.

IamWe says: Sorry, this is not a step by step instructable. It is 1 enthusiastic story about a device using ZPE? with a lot of 'jargon'. Why no short specs to start with; why no short comparison with 'normal' motors. This instructable is more a mission statement, but not made with somebody in mind who wants to reconstruct this thing. Sorry to be critical about the form you put this instructable in. I really appreciate this kind of projects, trying to save energy on household appliances. I wonder how much energy(money) you can save with this rotovertor on a washmachine?

sparten11 says: been there done that. Only way to work is to use back emf to store and re enter the power matrix. action reaction is only way it works you will never ever get more out than in. sorry just fact. the only thing you can do is gain more efficiency or get closer to 100 percent you will never go over. if you did then we especially myself would be driving in my free power car. not there yet. not to say it can't or won't be done. just don't think this is it.I will investigate more. I know several people in this field and I am know to most of those whom are serious in this endeavor. If this works I will let you know in a few months. I will test and evaluate it.

Heer_Lorcan (author) says: 1 year agoReply -- Unfortunately as to my and others experience.

This works. Test it, read up on it. There are at least 3 yahoo groups about it. EVGRAY,

EVGRAYTOO and EVReplication.

when configurating the Prime Mover to 460V and use 110V @ 50-60Hz. The Prime Mover remains cold. Use a High 100mF - 460V oil filled capacitor to start it. Find the resonating capacitor when rotating at full speed. This lowers the usage of amp. The second electromotor (alternator) when changing the rotor upside down. (look it up). Produces more amperage then the Prime Mover need to run. Hope this helps. Here is a diagram elektromotor. Point A is axis for gear, point B is where fan is. Remove fan. only change rotor, leave stator in same position as when removing rotor.

A ---********--- B (rotor normal position)

B ---*********--- A (rotor upside down)

Step 2 :

Pictured before are two RV's coupled together. One is acting as a generator and the other is acting as a prime mover. On the hand right side the meter shows the generator's reactive power out put. On the left hand side is showing the RV's prime mover's input in watts.The reactive power shows:

119.8 x .8 = 95.84W INPUT
203 x 5.1 * 1.732 = 1793 of virtual reactive power
Potential COP = 18.7

From this picture one can see what is conventionally regarded as "reactive power" operating

in the RV. The intent is to extract this reactive power into usable watts and create  a

condition that is non reflective to the source, or input side. Several versions of these

configurations are presently on the R and D design board.

There have been reports of various individuals who have converted the captured reactive power back into a usable form of energy. These individuals and methods are listed in the technical compilations as a point of reference. To date (2009) none of these referenced methods have made it into public hands.

Also none of these methods have been given to the public open source.The only method which has ever made it into public hands is the open source process disclosed by Hector. This is by using the RV's unique power management teachings and principles. At this stage the training starts with the application of the RV in energy savings applications. This is then able lead to a higher power amplification understanding (tunning). This must be understood and experimented in steps.

Step 4:

This is another device like the RV which has demonstrated potencial over unity efficiency and is needing further study to extract the power in a condition which is non reflective to the source. Here is a technical and instructional compilation.

Trans-Verter research and development

The research and development of the RV has been extended and perfected by open source engineers known to Panacea-BOCAF, many improvements and potential are shown in the technical compilation mentioned on this page.

We must state again that to reach the capacity this research and development has, the RV and engineers known to Panacea- BOCAF need to make it into a resourced backed granted environment, where their disclosures can be secured into public knowledge and perfected.

The RV can also be applied into cogeneration roles with certain expired energy patents which the public can also benefit from. To date certain expired patents are able be fused with the RV. Many generators can be adopted to the RV prime mover and run in RV mode for high efficiency use as Norman Wootan proved in his replicated test. Further technical details of this are contained in the compilations mentioned on this page.

Hector plans to experiment with the Ekhlin brown patent as a generator attached to the RV.  Another one of the expired patents which can be used in cogeneration with the RV technology is the expired lee Rogers’s air car patent. Further technical detail are contained in the compilations mentioned on this page.

The concept disclosed by Hector is to run Solar + RV + air compressor + lee Rogers patent.

The expired patent can be built and tested with the RV and publicly disclosed and owned. To date an open sourced team member of Panacea is working to perfect this RV-Rogers co-generation, but is under resourced and lacks the time needed and money to complete the project. In the centre this will be resolved.

I have a friend that said he has a rotoverter and it provides 80% of his energy requirements (electricity that is). I found this science fair report interesting (From USC):

The students do state that they produced excess reactive power, and mention two possible methods of extracting this. Anyone have any experience with the Rotoverter?

This seems to be the best introduction video of the technology:

Here are the instructions on how to extract resonance from the RotoVerter:

The PDF starts with:

"A very effective additional circuit has been developed by David Kousoulides. This circuit allows extra current to be drawn off a RotoVerter while it is running, without increasing the input power needed to drive the RotoVerter. David's circuit can be used with a wide range of systems, but here it is being shown as an addition to the RotoVerter system, raising it's efficiency even higher than before.

As is common with many effective circuits, it is basically very simple looking, and it's apparent operation is easily explained. The objective is to draw additional current from the RotoVerter and use that current to charge one or more batteries, without loading the RotoVerter at all. The current take off is in the form of a rapid series of current pulses which can be heard as a series of faint clicks when fed into the battery.

I have a 600 lb. rotoverter on my driveway. 25 horse power 1160 rpm. It will run on an 120 volt ac lamp cord. It is supposed to pull over 30 amps at 460 volts. This is my third and largest rotoverter. I could never be sure on the small ones if my measurements were correct. Now I am sure. I tested with the Phil Woods double plug and dc motor system and just with a prony brake and analog ammeter. It is never over unity. At it's best it can be tuned to put out 1 hp using about 2% more energy than 746 watts. In other words it is a dud. Who wants a 600 lb. one horsepower motor... It has to be re-tuned for each load. Tesla was the greatest motor man who ever lived. Where is his rotoverter patent? If there is anyone who would like to prove me wrong on this they are welcome to come here and test this. I would love to be wrong. And no I won't spend any more time on it. Anyone who wants to use it may do so just as long as they come here and spend their time.

I watch rotoverter work with mild interest. My results were much the same. Possible cost savings if you build a controller to handle idle rpms.

What gets me is some recent inventor gets the credit when farmers have been doing this for many decades. It is a solution for operating 3 phase motors on single phase. The efficiency is always very poor except when idling. They all run like a badly timed Harley V.

Re: ROTOVERTER (2010-10-30 )

No one ever said RV is OU but its a VERY efficient motor like 99%.  It can never go OU within itself unless method used to cover the 1% losses. If it could and it has happened under certain pulse drive conditions the motor goes into incremental frequency latches and accelerated to 30,000 rpm and explodes like a bomb.

Best I seen is 10HP motor running on 11 watts. So where does the energy come from which is actually driving the motor? The answer is magnetic! Like newman the "power" in converts to VARS and high volts no amps creates local electron spin stress creates high magnetic fields. Its this which drives the motor the 11 watts is just the "energiser". To see this in action is 1000 times more exhilarating than any joule theif flashing an LED or ###### bicycle wheel:)

 BUT it can go OU when driving another 3 phase motor and use the 3rd phase leading edge as gain typical 1.618 by the book and i have seen it draw 100 watts and provide 160 watts o/p on several occasions. Or you can drive a single phase motor and use that to recover the losses to the prime mover. This method has been looped and documented using pulley 5:1 ratio, banks of caps and 1000 watt inverter to get the thing started.

The best gains are when RV drives an axial perm mag generator. Or you can make one by modifying off shelf 3 phase motor and fit neos on the rotor to make a synchronous generator. This will provide a PF >1 back into the mains supply and drastically lower the electric bill.

I don't have time to trawl the net to show you all the experiments but looping is real i seen it too many times on private skype calls not everyone likes to shout about looping. This one of the better ones. A good neo generator is OU only needs the gearing sorted and cap bank to loop it. THis Would work perfectly without water RV driven.

The rotoverter is a myth in my opinion. It is an efficient motor but I don't need a 600 lb. one horsepower motor. Joseph Newman has a similar problem in that his machine puts a tiny fraction of horsepower for its size. I have a pump in a solar tank of 4000 gallons that will pump the same gallons as Newman's multi-ton setup. It uses ten times as much energy as Newman's (400 versus 44 watts) but Newman's setup would not even fit in my tank which is 8' x8'.


Hector advised you NOT to use a 600lb motor as RV efficiency works best on motors 3 to 10 HP. Also while RV works to about 1/4 plated value this is only true for 50/60Hz operation. Now you are stuck with a monster on your drive which requires a crane to move it.

This means a 10hp motor usually only 72% efficient can run at 99% efficient at 2.5 HP in RV mode.

If you need 50 HP from a 10hp motor while running it in pure RV mode then change the bearings to HS ceramics, balance the rotor and run it at 30,000RPM and you get your 50HP. The faster you run the more horses:) Of course needs pulse drive and will still idle on a few watts at full speed.

Now can you see why Newman motor is only a demonstrator of resonance technology but impracticable? RV is good off the shelf and can be tweaked at very low cost ie bearings and frequency drive will piss over anything else bang for bucks. Even Newman knows this as stated in his video "speed is power" but his pile of junk motor can hardly muster  300 rpm LOL
Explanation of energy savings using the RV mode

Running three-phase motors in the RV mode is a method to operate a motor at high-impedance to its input source by using electrical resonant principles. In RV mode the three-phase motor is wired to operate from one-phase power by using the addition of start and run capacitors to generate the third phase.

The RV principle is based on matching the source to the needs of the load (as referenced by Nikola Tesla) by tuning capacitors values to the load REQUIREMENTS. This will result in an as yet unrecognized superior power management with many other advantages.

The process of electrical resonance in the process of the RV allows a lower reflective power loss/draw when the motor idles. When the motor is loaded, the RV functions the same as a true transformer does.
An electrical transformer uses minimal energy in its primary winding when unloaded. The RV functions the same by using minimal energy at its input when its MECHANICAL output is unloaded. This is the most efficient Power On demand process; Normal electric motor engineering design has an inefficient power management process.

The RV solves this design flaw and also makes practical solar co-generation possible (consult video: RV running on solar panels), where previously it would have been impossible. The benefit of running motors in RV mode results in superior energy savings when used in the role of industrial and commercial machinery, intermittently in rotary punch applications.

Even at this very early R&D (of energy savings) stage, all 1-2 horse powered motors that are run in the RV mode can save energy in applications which employ a lathe, a drill a grinder a rotary saw, a reciprocating pump, and also vacuum pumps. But this is only the beginning.

Technically, when operating a motor in RV mode, at the start of the process the function is resonant; as the squirrel cage motor attains rotation the conditions allow a an impedance match with the line input power source. As you load this tuned resonant state it tends to go back to a semi resonant state where the power can be used more efficiently than in a normal electrical motor design.
Another explanation of energy savings using RV mode

A "rotoverted" AC motor can best be described as an off-shelf 3-phase AC motor with its phases reconnected very simply to run on single phase AC input (house grid for example), and with only 2 of the 3 phases in the motor connected to power source. START and RUN AC caps are connected between phases 2 and 3 (#3 being the "unconnected/virtual" phase)


The RUN cap cap be adjusted in its UF value to create the lowest input draw possible for whatever load the shaft may turning. (rotoverted motors can be "tuned to load" easily via run cap UF size)

Various generators and alternators, or even a 2nd 3ph motor hooked up to work as alternator, can be turned by shaft to demonstrate "overunity" (more watts output than input)

Any person with ability to read meters and simple circuit diagrams can build and test a rotovertor power system...AC 3ph motors can be found for free and very cheap and the hands-on conversion takes about an afternoon.


RotoVerter is: A remarkable piece of energy saving engineering that can be applied readily to off-the-shelf components. Utilizes an AC motor - with a modest change in the wiring, a motor rated to run at 460 volts on 3-phase, at 20 - 30 amps, can be made to run on 120 volts single phase, and on a handful of amps (5 - 7 amps). This is done, by creating a virtual 3rd phase utilizing capacitance. By tuning the capacitance, the motor can be put into a self-semiresonant condition whereby the motor runs with extreme efficiency and is cool to the touch at full rated rpm. This is a PROVEN technological advance - which can be put into operation worldwide to help stem the energy shortages reported to be on the way globally.

This modified AC motor is referred to as the RotoVerter. Several first-hand who have replicated the device are seeing amazing results as the extra voltage circulating in the capacitor bank used to create the virtual third phase, can also be utilized to charge batteries as well and other loads. The beauty of being able to run these motors in this manner, is not only the tremendous energy savings, but provides one with the ability to go SOLAR as well.
