@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

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 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.

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,

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.
