Take a look

John B,

Ok, it looks like we can match your coils if my math is right…

Slave____________Center__________Slave
10.2 ohms_______4.0 ohms________10.2 ohms___=___2.2 ohms

Slave coils…
31.92 lbs. or 3200 ft.


Center coil…(based on all windings in parallel)

Power___________Power__________Control_________Control
12 ohms_________12 ohms________24 ohms_________24 ohms___=___4.0 ohms


Power winding
12 ohms or 37.55 lbs. or 3775 ft.

Control windings
24 ohms or 18.69 lbs. or 3760 ft.


Let me know if this looks right. Attached is our updated drawings…


Thanks, Brent

Brent,
This is what I'm measuring with my analog meter. I asked Rick and he said the same thing as I got charged for 4 buckets of wire. My LCR meter will be done tomorrow as it is way off for some reason. Please when you do this add a little extra wire just incase I have mad an error also. I want to see your machine running and everything will change after that for the better.

Excellent work with the drawings this is the way it looks on mine. I will make all the measurements over again just to be on the safe side. make the side coils adjustable so you can move them if need be as that is what I had to do, you will see that the magnetic fields are big. try not to exceed when it is running over 20 RMP's
Now back for now to my other work on Stubblefield.

John B,

Thank you SO much for your patience with me through all of this!!!

I can't take any credit for the drawings...Scott (txaggie00) has done all of our drawings and CAD work. He has done an amazing job!

Looking forward to the next phase!


Thanks again, Brent

Txaggie00,
Thanks for the great drawings excellent work.
Thank you.

Thanks

Thanks John!
We needed to replicate your wheel as close as possible. Getting this machine right was extremely important to us. We have so much to learn from it and are eager to learn it. As you said, we have been bitten by this bug too.

Thanks for your willingness to help us and everyone else!

Thanks,
Scott

Txaggie00,
Thanks for the great drawings excellent work.
Thank you.

Bedini 3GT Schematic

Hi All,

A few people asked for a schematic of my current 3GT schematic, so here it is...

Wire Measurments

Hi, John B, Brent and all,

Based on my Mathcad AWG Magnet Wire Calculator,

and based on JB's posted DCR measurements and my understanding of the 4 15Ga strands hooked up as the drive coil circuit......
and the 2 18ga control strands are not apart of the drive circuit

Main Coil
for 15 Ga wire, 767 meters = 2516.4 Ft = 8ohms at 25.229 Lb

2 in parallel on the main coil = 4 ohms at 50.458 LB

Slave Coils

15Ga 978 meters = 3208.661 Ft = 10.2ohms at 32.165 Lb

2 Slave coils in parallel = 5.1 ohms at 64.33 LB


4 strands of 15ga in parallel, 2 on main coil and 2 Slave coils = 2.242ohm total Drive circuit resistance, total weight = 114.815 Lb 15ga wire

767 meters of 18 Ga on main coil for mag amp control = 16.069ohms at 12.635 Lb
2 strands of 18ga = 25.27 Lb

Main coil Weight = 75.728 Lb

140.058 Lb 3 Coil weight total

JB, if the Resistance measurements change, when you get your meter back, than i will tweek these values to match it......

Thanks as always, for sharing everything with everybody....

John K,
I would put a 1.5K ohm Resistor between the input voltage to the hall and a zener diode to GND to keep the hall at 15 volts. If you use 36 volts you will burn that device out. This machine runs at 36 volts. Just something to note here.
John B

[John_K]

Hi John B,

Thanks for the help.

When I was running the 3GT at 36V I connected pin 2 of the hall to the negative of 12V to prevent the hall from burning out. But I will do as you suggest to keep the hall at 15V. What size zener do you suggest to use?

@RS,

It is my understanding that all 4 windings on the main coil are in parallel (power and control). Looking at the pictures and from what I remember at the conference, there are only two wires that are coming out of the main coil. Someone please correct me if I am wrong.

Thanks,
Scott

[RS_]

Scott,

As I was not at the conference, I do not know for sure...

If all 4 strands are in parallel on the main coil as a Drive Coil, then how do the 2 18ga control wires, control anything as a Mag Amp....?

John K. Ask JB about this in a earlier post......... and I think that these control wires need to be biased in a certain direction, at certain times in the Drive Coil Duty cycle, to function as a Mag Amp......... so that the turn on bias point of the core, is different from the turn off bias point of the core

I could be wrong......

Revised Schematic

Hi All,

Revised 3GT schematic, based on suggestions from John B.

Updated Schematic

Thankyou John K for the updated schematic. Was wondering what size cap you ended up using. I'll add the zener as soon as John lets us know which is best.

I just wish I could get youtube to see some of these great videos. Can't get youtube in China. It will have to wait till I get back home to Usa. But just love reading all the progress everyone as done with John B. helps.

Keep up the great work
Thanks again

John K,

i guess John B suggested to stabilize your Hall this way:



Use a 15 V zener to keep the input of the hall at 15 V
Nevermind the strange type for the hall, my database did not have a hall symbol.

Regards Itsu

See post 666( ) .It shows the hall protection with the zener.
