The Master Of Magnetics "Steven Mark"

[otto]

Hello GK,

do you know how much wires I need??

3 "special" controls and 3 1 turn collectors. Nothing else in this moment.

Time needed to wind my coils and make a TPU: lets say 1 hour, this is more then enough.

Weight of my newest TPU: less then 100 gramms

End result: no comment in this moment!!

Wires used: ONLY COPPER!!

Cost of such a TPU: a few bucks, or euros.

Of course there will be a lot of models with iron, aluminum....  for what???

In my last post I claimed something about heatsinks. Imagine: a rotational magnetic field with a speed that is hmmm.....like a bullit from a gun. Now imagine everything in this ring is hot, the coils are really hot because of the high frequency current, and now imagine what is such a hot rotating magnetic field doing with the iron or aluminum heatsinks of your MOSFETs.

Just think about it.

hey Otto, you said the coils untill now were all wrong design, can you describe in a few words what's wrong so we can start wrapping them right?

Thanx for all your input.

@ sauron

and im not trying to be rude or make anyone angry  but if you look back a page or 2 in this thred i think you will find your answer i am now rewinding my BLACK HOLE SUN  the right way

"The open TPU is an aluminum cable reel."

What do you mean by this ?

When you say 'open' , what are you referring to ? The TPU that was cut up ? The larger diameter TPUs ?

When you say 'aluminium' cable reel do you mean a reel made of aluminimum or do you mean a plastic/cardboard reel wound with aluminium cable ?

All the cable reels I've seen have nothing like the proportions of the TPU, which means the cable reel must have been cut down into what ? an aluminium cylinder ?

What pictorial evidence or otherwise do you have for suggesting  that an aluminium cable reel is used ? I have seen nothing on the videos or in SM descriptions that would point in this direction.

Giantkiller, in anticipation of your considered reply, many thanks.
