Bedini Ferris Wheel Regauging Motor

and a wisker under 700grams of wire per drive coil, so 1.4kg of driver per coil

Greetings All,

ive made almost 20 ssg type machines too play with the geometry, the more exciting potential ideas i try, the closer i realize JohnB is on the vacuum series with seemingly somewhat arbitrary figures...

but after 2 years tinkering, i came across something ive never seen before, and i have no idea whats happening or why, dont get too excited though because sadly its a problem,

the motor is running, but producing no backemf, w-t-f.. im running on the usual 12.4v +\- input , and draining 400ma over a trifilar coil (2 drive, one trigger)

usually when this happens it means the neon died, but i stuck my finger over the transistors and they are no longer making me involuntarily jump

17 gauge wire and 22 for the trigger,

the ideal coil geometry ive experimentally found too be is 9-10cms long, 7.5cm wide, with interior core diameter too small for my thumb too squeeze into, yet big enough for my middle finger with some wigglin space

1am now, il pickup some new trannys tomorrow and post how it goes

John B,

Were you able to determine what is going on with the neon lights?

Also, I think we are close on the circuits. Can you recommend a good op-amp device!


Many thanks, Brent

Comparator Circuit

John B,

Have a question about the comparator circuit...

Can you tell us what the comparator circuit is comparing? Since it appears as if the only input is the capacitor voltage, is it comparing the negative potential against the positive potential? At what point does the circuit determine that those are at a point to release the cap across the battery. Can you shed some light on what we are comparing?


Thanks, Brent

Neon light

John B,

It's on the standard Bedini/Cole circuit...

Let me clarify. When we first got the wheel spinning we were getting lots of heat on the transistors. It was recommended by someone to put the neon lights on to help save the transistors and what we noticed was they would only illuminate on the 93s. (I think I said 94s earlier). Just watched the video again for a refresher on...Post 1403...that Scott had posted.

Not much experience with the Bedini/Cole circuit, let alone coils of this size! Any input would be greatly appreciated!


Thanks, Brent

Brent,
What Neon light, are you using the bedini /cole circuit? hope your not running the SG circuit.

John B,

Yes, our coils are exactly the same size as your 13 ft. BFW...

What would cause the neon light on the MJL21194 transistors to flash?


Thanks, Brent

Brent,
If I remember your coils are just almost like mine, if not you can tune it this way if need be. You will know as the capacitor will be slow to charge. The current in the bi-polar switch is important. Eric's machine was charging at about 300 Ma when it was running. For that machine I needed 1 and 1/2 amps on the analog meter to the charging batteries. The extra coil allowed me to tune it. I wish Eric had more time as I was going to try something else with that machine. Eric also had a very small bi-polar switch which did not help, but worked well for the show. If you looked in my box at the show my switch was much bigger with all matched devices. Again when the tuning is right the machine will increase speed. I need to buy a battery for my camera as it is had it and cant be charged, the world of lithium computer controlled batteries.

Hi All,

Just wanted to add that when I was talking to Erik after the conference about the 13' wheel we spoke a lot about tuning.

I wasn't with John and Erik when they were tuning Erik's machine, but I do remember Erik saying that on the 13' GT3 the 2 slave coils were mainly there as tuning coils. I believe that John wanted them to tune the main coil, but rather than have them sitting on the base he decided to mount them around the rotor to use them to generate more torque.

Now we see that on John's GT1 that he showed at the conference he still has the 2 slave coils and also the air cored tuning coil. All of the coils are wired in parallel. I really think that John B has further advanced the original setup by adding the air cored tuning coil. This will make it a lot easier for the guys that are building to get the results they're looking for. I imagnine you could to a similar trick with an SSG circuit, but that's just a hunch.

@John B, feel free to correct me if I've got it wrong. It's hard to remember every detail of what I heard and saw.

Les K,

You are correct...

We are diligently working on the circuits and the other items that we picked up on at the conference...one step at a time! Still lots to test, lots to learn with lots of questions. Glad to see the thread activity again!

Maybe we will have a video (post conference) to share soon.


Thanks, Brent

I am about 100% certain Brent and the others are deep in their shop right now no doubt we will hear from those Texan's pretty soon.

Tuning Coil

John B,

Are you saying that we will not have to add an additional coil for tuning?

And if not, how do we determine the right impedance for our machine?

Scott and I are still working on our circuits that you showed at the conference, but the circuit that we are using now (standard Bedini/Cole) still flashes the neon lights that are attached to the transistors. It is only on the 94s. Is this an indication of not being tuned? Any suggestions?


Thanks, Brent

To All,
Some things you can do to test if the coil has the right impedance.
and checking to see the cap is getting the most charge.

For those that have gone to the conference. I explained that the machine needed an extra coil to balance the impedance out so this is an easy check. It should work with the original Bedini/ Cole motor switch. Brent, your machine from what you said should almost be right on.

Sorry this Forum is very quiet at this time when it should be hopping. I hope this little spat between digital and analog has not discourage you from your work as I just ignore it all, it's not important who is right or wrong. It is important to finish your machine and get it working.
Hope this gets more active soon. Another thing almost left out,
use a low impedance coil to check around 3.3 Ohms, you can clip lead it in the circuit, you will know if the machine speeds up.

Thanks John,
Look forward to your reviews. I am about 100% certain Brent and the others are deep in their shop right now no doubt we will hear from those Texan's pretty soon.

I have been reading Tom beardens work for some time I should be finished soon in about twenty years or so... You are both heroes in my book.
Any way thanks john for all this help. Things will really start popping when we get those pulser circuits...

Les

Argh... That's a pun on popping nothing more...

Les

[Les_K]

Les K,
Yes I go along with you so I ended the subject because we both know and the others are just finding out.

Les, Tom Bearden has been at this for as long as I have known him.
Yes you must tune the circuit I did this for the show model John K had some good insight on all of this as I showed him and Eric how to do this when they could not get the machine to run.

You need to be at about 1 ampere or more with this circuit. so it is important that all the devices are matched at about the same current. For you guys here I will see about running some you-tubes on the demonstration that I gave at the conference. I think we all need a refresher here.

Les that coil can be an air coil away from the machine as the current oscillates between the two. Let me see how much time I have tomorrow to do this for the group. I will try to do the switch also.
John B

this is the pancake generator right?
10 kW, 15Phase Axial flux pancake generator for 2-blade Wind Turbine

I have used an air coil inline w/ the power coil using the bipolar ckt in a window motor. here is an example of what I did:

‪Window Motor - adding coils in series‬‏ - YouTube

it both speeds up the rotor and lowers the amp draw.
I will see what it does to have it in parallel - I was not at the conference so I have no idea what I am looking for. any enlightenment will be much appreciated.

This is starting to get very interesting and I will test all this ideas even though I did not even see this machines, coils or circuits.
John mentioned:
"THIS IS ESSENTIALLY, A CIRCUIT OF VERY HIGH SELF-INDUCTION AND SMALL RESISTANCE"
Adding an air core cole of low resistance in parallel with the main coil will certainly lower the resistance.
But coils in parallel will also lower the inductance. I did not measure yet but could it be that the air core coil has a much lower inductance so that putting it in parallel with the big coil the resistance goes lower a lot more and the inductance only a little?

John you also mentioned the air core , neo generator. I guess it must be much like a wind generator. Or did you mean that we must turn Tesla pancake bifilar coils and use that with the neos.
Now that I read it again it looks like you mean a pancake shaped generator with air cores.
