New comer needs any and all help

[WilbyInebriated]

OK.... well, I just wound a coil "sort of" according to the Bedini diagram above and my wire. I have a big spool, over nine pounds, of #27 magnet wire, so I'm trying to use it up. I took two smaller spools and wound them up so now I have three spools of #27 AWG enameled magnet wire. I made a bobbin using my hole saw to cut out some disks and I used a steel bolt for the core, it's a number 10 bolt and I put a piece of heatshrink on the bolt to space the end disks at 1 1/2 inch apart. Then I chucked the whole thing in the drill and took the three strands of #27 from the three spools and wound 800 turns onto the bobbin. Before I started I twisted the two ends from the smaller spools together so I could tell which were going to be the "thick" wire. I made some little holes in the end pieces for the wire ends to come out.

The 800 x 3 turns of #27 wire, the bolt, the end pieces and the feed wires altogether weigh about 9 1/4 ounces. So you can figure up or down from there for your wire, whatever's available. There are online calculators that will tell you exactly how much weight, length, number of turns, etc for coils of all types, just google "coil wire calculator" and have at it.

I also made a video showing testing this coil with a 2n3055 transistor and some magnets spun by the drill. I'm uploading it to YT now and I'll post a link when it's done.

why are you totally deviating from any of the posted schematics and calling it a "bedini coil"?

Just to piss you off.

Do you really think that using two strands of #27 is significantly different from using a single strand of #23? If you do, then I suggest that you demonstrate the validity of your contention by winding some coils and showing how they materially differ. If not..... then just go back to being helpful.
And if you examine the diagram I posted, that is in BEDINI'S OWN HAND, you will see that he specifies up to 800 turns, he does not use a 2n3055 like the diagram YOU posted, and he does not use a neon.

So why are you posting diagrams and calling them "Bedini" schematics, since they don't look anything like what BEDINI HIMSELF drew? I'll tell you why: it's because you know enough about what you are doing that you can make reasonable substitutions and variations and still expect the thing to work just as Bedini himself intended. Not only that, but also Bedini himself published many variations on the same basic circuit.

Haha. Nice!!!
I don't care if its the way bendini drew it or not as long as I can get this rotor to spin like it should..

you failed... all you did was demonstrate your usual lack of attention to detail...

if you examine the diagram YOU posted, that is in BEDINI'S OWN HAND, you will see it specifies BIFILAR...    and what gauge does it specify?

but enough of your asinine red herrings... i'll ask you again:

edit: we are trying to help this guy get a working pulse motor based off the simplified bedini circuit. a guy who is an admitted beginner. stop adding confusion with your trifilar...  

[TinselKoala]

Wilby, you are the one adding confusion. In no sense is my coil "trifilar" electrically. I simply used two strands of #27, tied together at both ends, instead of a single strand of #23.  You will note that Bedini says "450-800 turns." My two strands of #27 have a cross sectional area of 0.204 mm2 and one strand of #23 has area 0.258 mm2. This means that my 800 turns of doubled #27 will have slightly more resistance than 800 turns of #23. The variation in the allowed length of Bedini's windings results in a far greater range of resistance and inductance than the difference between a doubled #27 and a single #23 strand at the same length. And do you really think that the difference between #26 and #27 is going to be significant, if the allowed turn range is from 450 to 800? You are really making yourself look sillier than usual.

Do you really want to help him get a motor working? Then make a video of your own, showing how the coil functions and what it's supposed to do. I will wager that mine performs electrically just as any other Bedini North Pole Motor coil of the same physical dimensions. I am a little uncertain about using the bolt for the core. We shall see how it works out, and if it doesn't work according to plan... .guess what, I'll wind another coil using my same #27 wire, unless you can PROVE ME WRONG by a demonstration of your own that illustrates a significant difference in performance due to my choice of wire gauge.
