Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

3 HP motor works with 116 V and 0.42 Amp. (But don't have enough power)

Hi all,
I used the standard circuit that made by Phil Wood. 3 HP, 3 phase motor worked real well with no problem all. The original wiring with no modification made, allow the motor run real smooth at 116 V  and 0.92 Amp. I further improved the circuit that drop down to 116 V  and 0.42 Amp by adding 2 more capacitors.
1-4 Mf.  and the other one is  1-25 Mf.

Now the problem is this: This 3 HP motor don't have enough torque power on the shaft? Do you guys know why?
When I turn the motor on and runs full speed at 1800 rpm, I can stop the shaft by using a leather glove.

Amount of energy uses to run is great, but how can I improve the out put power of this motor?

My feeling is that RV is not efficient under any motor that 7.5 HP 

I'll greatly appreciate any comments on my circuit.

Mem,

Just to say, you can stop a 1/2 hp motor with leather gloves or a rag.  I have done that before, thats how I kinda figure out how much hp my motor is putting out.   If I cannot stop it, then I know it's putting out more than 1/2 hp.

Later,,,,,,JackH

I also would very much like to hear from someone who is a proponent and believer in the idea that you can get more power out of the shaft than you put in electrically in these RV setups.  Can anyone answer this fellow's questions?  He is being very clear, sincere and direct.  He has been led to believe that this is a well-known, accepted and working approach to saving energy.  Based on that belief, he has spent time and money.  It sounds like he's thinking of trying it on a larger motor; spending more money and time.  Now it doesn't seem to work that well after all. Why is most all the shaft power gone?  How come he can't get more torque?  Could someone please explain? 

Does he use the wrong capacitors?  Is it hooked up wrong?  Should he expect to lose some shaft power with this approach?  Is there any kind of accepted formula to predict how much power he will need to put in to get a certain amount of shaft power out? Or is he to expect the full rated mechanical output (or very nearly) despite putting in many times less electrical power.  Can a true proponent who has had success with RVs please step up to the plate and answer these questions for Mem?

I have my own opinion, based on the old-fashioned idea that you can't get more out than you put in, at least without doing something very very special and mysterious and totally new that has not been achieved as yet.  Something much more than adding a passive device like a capacitor. 

But that kind of opinion is not popular here, so I just wanted to add my voice to Mem's and ask for someone who believes in this and can explain it clearly to please answer Mem's questions.  Thanks!

Dear Humbugger,
thank you for adding more voice to my unspoken words... I am not a theoretical guy, I just know how to built things if there is a logical circuit.
This "Rotoverter" has been interesting and fascinating project to me, jut like you said who wants to vested he's time and money? Which is so true. Yes I did spend energy, time + money for above project what I have describe. All is good I have regret at all. But please hear us here and give us some a clear direction.

I wish that those who have advance knowledge and more hands on experience will come forth and "truly share" in the name of simplicity and truth. Perhaps it just a matter of time that right person will show up and tell us what's truly going on with "Rotoverter" here?

There is no question about 3 phase motor that runs with 120 AC and resonance, that's very clear to me. But, in order for us to be fully informed about free or efficient energy technologies we need to disclose of our findings and let our fellow man to be able duplicate the technology clearly.
Or else "our selfishness can/will consume our fortune" so to speak.
So many inventors died with their inventions, WHY a Nobel man looses he's nobility right after he's been given little vision and knowledge of mechanical solutions of physical world.
When the soul departs from earth plain, leaves behind all physicals things he has accumulated on earth, but accumulated good that he has created, becomes like a rocket fuel that propels the soul in to the higher octaves of Light.

Selfishness and various other perversions becomes like a concrete blocks that are attached to space rocket (soul)   

We have been separated and concurred enough from the begging of the time and man is truly been developed to be a modern "slave" of moneychangers in the land.

Creativity is the inner intuition of the soul; no soul can be made progress in spiritual path unless he/she will use their creativity to serve small or large number of people.

Dear ingenious and creative brothers and sisters across the Globe let us arise against the opposition that keep us continuously depend for their energy production/control and let us create and share non polluting and free energy technologies solution that untimely can be adaptable to every way of our energy needs. We can do this.

If we did this in past we can do it at the present too. Therefore I implore you one an all to freely share our solutions that can never be bought and locked up or will never be lost again!

And if we?ll ever do this, some day we?ll look back in time and see the profound good that we have done that affected life ways that we have left behind, therefore we shall be liberated from the shackles of human creation to move on into other octaves of Light  beyond this earth plane, for the work well done?

Because we have other worlds to concur? Mem.>>

I believe the simple answer here is that when you lower the current going into any type of motor, or device for that matter, you're going to get less power out.

With regards to these types of pulse motors (correct me if I'm wrong, I haven't studied Rotoverter designs well, but I was under the impression that the rotoverter motors were pulsed), or any type of brushless motor (like the type used in computer fans, which use hall-IC's), the current determines the torque, whilst the voltage determines the RPM (to an extent... you have to supply the minimum current to get it to speed, and after that the speed stays relatively unchanged if you continue to add current).

Therefore the RPM's will remain the same with your design, but by lowering the current you lower torque.

Thats just my theory anyways.
