@Groundloop
What are you using to do the drawings?
The on/off switch is before the converter just after the 47000uf capacitor.If I start with the converter on it is more difficult.
We can have a switch at the input and at the output.
The generator is on continous run for the last 3.15 hours.
I'll leave it running until neighbours will complain about the noise.

Hi Romero,
Do you know if the multi-stranded litz wire is really necessary?
I know it handles high frequency better but have you tried normal wire as well?

Thanks!
Steven

@romerouk,

Microsoft Windows Paint. :-)

I have updated the on/off switch position on the drawing a few pages back.

Yeppeeeeeee :D :D :D

hi all

so good i am at the weekend and deliciously drinking a pure malt whiskey.     SANTE A TOUS     it's not every day we have something like this yeep!!

Thanks Romero for sharing. And yes i use and reuse your very simple driver circuit exactly as it is presented here and it works great. Just have a look to what i-ron sayd and the proposed FET driver circuit (from GL) for more powerfull next evolution, there is full of helpfull impulse

Thanks of course to Groundloop for its really fantastic works and shematic proposals (for the futures and probably inombrable replications)

Thank's I-ron for the very interesting link to the HALL-effect sensor. Wow !!those small things can be used very differently, i will surely profit of this in my future experiment.

I Tyson (skywatcher ) i should propose that you use only 4 magnet rotor with your 10 coils (5 pairs) so you will not have too much distance to overcome between odd and even. And good luck every experiment is usefull.Thanks

I was almost sure that Toranarod would  come here ---Bienvenue to you---. Yes with your great experience you will surely help here.

And of course thank's to all other contributers. Every idea is necessary and can help

OK i am in front of my order list and my small lab desorder , looking in the drawers what is missing    and strong thinking how i will do it .Probably i will follow step by step the GL (Romero ) shematic to be sure to get the result -.

My question is the stranded wire.  Romero has alredy answered this question , but is there somebody who  can explain what is the electrical advantage of the standed wire . I say this because i have plenty of plain wire here , and no stranded wire. But of course for this exceptional replication i will not hesitate to order strande wire, (and will do anyway ) Any suggestion ?

  and very happy to be with you ---the power is there and concentrating

and another time YEEEEEPEEEEE :D ;D ;D ;D ;D ;D

good luck at all

Laurent

:) I tought u use something more professional.
I call myself an IT engineer and I don't recognize something simple like that... bad for me :)

I do use other design programs also. But the Paint program is good enough for small and simple circuit designs.
Once you master the copy/paste and zoom in/out then you can make drawings very fast. :-)

I have moved the switch and updated the drawing with a 47000uF 25V cap.

@woopy
good to see you arround.
Regarding the stranded wire:
Some time ago in a Bedini project I have built 2 identical coils but one with normal wire and another with stranded wire.I was using this coils to collect the power from the rotor powered with a Bedini standard circuit.Same core same wire diameter, all the same...
The results at that time(no load):   normal wire output was 9.2 volts
                                                stranded wire output was 12.3
since then I have always used stranded for most of my coils
it is easy to do the same experiment like me, actually it would be nice if someone else will confirm this.
I always try everything myself, I don't take all info I found as granted.
If I was wrong I would like someone to tell me.

@Groundloop
one more change to the drawing: input cap 47000uf

Thanks for the info on the wire
thats all I need to know that is a good reason
cheers

this is to important to pass up
I am going to build one, I am not stopping my current project as it will work
as well. will have two motors on the go.
keep every body posted
cheers

Me too!

@Romero.

Excellent work man. I will replicate this too.

Would be possible to take good close up pictures of your motor of every detail and post it? sometimes pictures can answer a million questions and also helps with documentation.

Many thanks,

Fausto.

Hi all,

How wonderful it is to see so many going for it.

I dont know if you are religeous Romero but, GOD BLESS YOU!

Regards, Penno

p.s. Rod, I thought you would like this.

This is what Bruce Tpu says also with stranded wire. If the freq of operation is high, there will be more skin for skin effect to travel in a stranded wire than a solid of the same awg.  What freq? dunno.

Bruce is using litz. I believe its when each strand is coated or insulated from other strands in the same wire casing.

I suppose the insulation whether it be enamel or something like telephone wire, possibly the separation electrically from each other helps in some way.


Good job Romero.  ;]

Hi penno,
Yes I am religious, Christian Orthodox, God helpped me many times in life.
I am curious to see how many will actually do anything, many are just waiting and waiting... don't know what.
Do not use shortcuts, if built like I said, reffering to the coils and magnets arrangement then everything else is easy if not will fail. I will show you how many rotors I have made before this one worked, all others looked perfect but small diferences.
Can you believe that I have ordered 2 of the acrylic rotors to a local company who uses laser cutting and I was expected to get a perfect rotor but... the centre hole is not centered and the spacing betwen the magnets on the rotor was not equal... I went crazy.I paid a lot of money for that operation to be done perfect and their excuse was that I was no very specific that it must be acurrate... what will I expect fron a laser cutting...
The one used now was ordered to another company that makes clock parts but the max thicknes they worked with was 3mm. I have ordered 4 and glued them togheter. The actual rotor u see is made from 4 rotors 3mm thick each.The rotor must be strong and not bend.
Today I have ordered the magnets for the next build and what is left is again the stupid rotor.
I have to go again thru the same pain, oh nooo...

All the best,
RomeroUK

Hi,
People should understand that when I am talking about stranded wire I am reffering to a bunch of wires isolated from each other.
In my understanding litz wire is a bunch of wires unisolated like in a normal power cord.
I am specifying this just to make sure everyone understands.
English is not my first language, sometimes might have some mistakes...

RomeroUK

@RomeroUK,

Litz wire has many enameled copper wires slightly twisted together.
(All wires are insulated from each other.)

I think you meant to say that you are using Litz wire on your coils.
