Muller Dynamo

You are correct Dave45

That's why I ordered those:

http://www.vxb.com/page/bearings/PROD/kit1002

They are very robust. I will have to clean the bearings and replace the oil inside because they have a little bit of friction, but they will endure the 20000rpm very easily.

Fausto.

Just wanted to pop in and state:

I may have learned all I can from Bedini energizers and decided I do not want to build a huge machine and basement full of batteries.
I have just finishing reading through 122 pages here and saved lots of files and references. (Thank you.)
I believe there is a major potential for this thing to work.
I am going to attempt this replication and have ordered a pile of parts. (Wish there to be a comprehensive parts list including sources.)
I am "ScorchGD" on youtube.

May peace be with you all.

"You wrote: Bill Muller also told me is that "all the amps is made on the first couple of layers of the coil against the core" which is pretty intersting...

If we were to extend this reasoning further, would it mean that a larger diameter core with less wire (and hence shorter coil) would be more efficient ?

And regarding the use of magnetite powder & fiberglas resin to make cores, how do you think the resultant core magnetic parameters compare with say, ferrite or iron dust cores ?
I mean, is it worth the trouble to cast our own cores, or would we get better performance from off-the-shelf standard ferrites or similar ?"

Kone reply:
Bill M also said that all amps is made on the first couple of layers next to the core, and all the rest of the power that the coil make sis voltage...forgot to mention the voltage part.

Also Bill M said to have cores the same width as the magnets which makes sense since then the fields would mesh better and no waste of flux....the length of the coil/core would depend on the strength of the rotor magnets - maybe do a paper-clip test and see how far the fields extend and then it is personal preference thing about jsut how far you want to make the core, according to how strong the flux is at certain distance....if it can pickup paper clip might be good test as good as any.

right now with the RomeroUK replications, I would stick with ferrite cores, since that is what he used, and as far as I know, Bill Muller didnt have those magnets behind the cores "regauging" magnets I call them...so what worked good core-wise for Bill Muller might not works so well when you have magnets behind the cores...Bill also had very special and secret-source blacksand cores too so its not something you can even buy anywhere anyways....ferrite powder mixed with epoxy might be fun to try but probalby not worth the hassle right now.

Welcome Scorch. There is here http://www.overunity.com/index.php?topic=10716.msg286098#msg286098.

If anyone has different parts let me know I can keep adding to my thread.

For those of you that are using the Tapplastic discs as rotors, what thickness magnet are you using?

@plengo, thanks for weeding out all the unnecessary posts, it makes it easier to get the good info.
