Bedini Ferris Wheel Regauging Motor

[Les_K]

Les, thanks for the pictures and video. I would've though you would get the fastest RPM with the way you have it tuned in the video as if I tune the same way with an SG I get the fastest RPM.

Try and tune it to the fastest RPM with 50% duty cycle and show me where the transistor turns on and off.

Ok Check this out..

This is when I have it set to just before the center with the given rotation. It is interesting how narrow the tuning of the hall actually becomes at this point. And what was interesting was that I began to see a slight curvature on the scope shot. But I could also tune very nicely at what point it reversed and began to kick forward. This was really cool as I could easily see at what point I was at and how close to the 23 degree mark I was. the battery went dead in the camera so I lost some of that.

Like I said the scope shot showed a slight curvature, so I added the Neo magnets and it really changed.

I would say that the curvature began to happen as part of the interferometry. since I did not see this until we got into the timing. And if there is a difference between this machine and an SG machine I would say that it would be the interaction of the interferometry.

At this point it is running nicely at about 1.2 amps and is charging quite well. I didn't get a scope shot to see what the rate of cap dump was because the batteries were pretty well depleted so I am charging them. But up to this point I would say the best this machine has done so far is about 50% efficient if that. So we will see what these changes have done.

Also as to the RPM's they are up but I haven't checked the actual speed yet. But I do know from all my experience with these machines the fastest rpm is not the best charging. the slowest is not either. 75% to 90% of the machines maximum rpm is where my best charging has been with my builds. but everyones builds do vary......

Lookin good!

Hey Les,

That's looking great!

It looks like you are pretty darn close right there.

I think it's time to just let it run and see what sort of charging and loading you get out of it.

Les, your timing looks dead on to me, the scope is identical to JB's and your dump happens exactly as JB describes that it should in DVD 28

have you played much with adjusting the mpsa06 to mjl21193 resistance? Maybe after you do a run or two...
thank you for keeping up with this and plugging away with it so we can all see and learn.

John,
I will run a few cycles and see how it does. The comparator circuit is the next weak link I am sure. But hopefully we can begin to look more into the machine itself. Since it plays with the magnetic streams, I would like to find out how to see more about what is happening in terms of the interferometry.

Patrick,
I will be thinking about this as well. Essentially this would be changing the timing between the rails.

Les

Sorry... what are rails?
Patrick

[Les_K]

Sorry about that,
In this case I am talking about the potential difference between the MJL21193 Collectors and the MJL21194 Collectors. Or in other words looking across the coil...

And from post #20
The currents are not important here in the front-end as this current is limited by the isolation of the power supply rails by the BEDINI/COLE switch.

In this latter case John is talking about the power rails themselves. But this is part of what I was thinking.

got it :-)
while the timing can definitely be changed, there is a fairly large window for amplifying the signal without influencing the timing or input.

Patrick,

When you get ready to run your big wheel try this cap dump circuit. It's similar to what John K posted awhile back just different components. It works well on my 5 foot wheel.

Add a small load to the shaft of your wheel and that will make the hall adjust a little less sensitive. The load represents the regauging motor load on JB's wheel and is necessary for final tuning. You can optimize for max torque at the shaft, minimum current draw and maximum charging.\

Ron,
I have some ideas for that, I thought a lot about air core, but that's not going to do it.
I think I have found my answer. But have some testing to do.

Ron,
Thanks for uploading that schematic. That's a nice compilation of the ckt and dump!

Les,
do you have one of these laying around?

might be a nice add on for a load :-)

back to work for me...

Patrick,
Nice, I'll have to look for one of those.

John K,

Ok I had a small problem I was able to fix. It's funny we didn't catch it earlier.
The two outside coils should create a south when the Center creates a north. I reversed the wires on the outside coils and the charging has improved quite a bit. I am probably at about an 80% to 90% efficient machine. So there is still some work to do. I am pretty sure a lot of those losses are in my comparator circuit.

As concerning the what happens when we switch off I ran into this video
Magnetic Monopole - YouTube

As I think about the outer coils being south and the center north, as well as why you wanted to get into what happens when the SSG switches off, I am beginning to see something new about the streams and how they are being separated. I think this relates to the videos at coral castle JB posted as well. What do you think?
