Bedini Ferris Wheel Regauging Motor

[Rl2003]

Redrichie,
It sounds like you made a sort of PMH with your coil. I have been playing with that idea as well,
and also with a normal PMH. I get a small spark when charging it. (shorting it to 9v dc)
Once you break the conection it should revert back to it's orig. state.

John,
or any of the guys here for that matter,
I posted this question to peter Lindemann but as I suspected it was in the wrong thread. I dont feel it belongs here either, But Peter said it was a good question and I should post it here.
To save some typing here is the post from the previous thread:

"I was not sure where to post this so i havent yet. And it may have been discussed in another thread I am not sure. But I have been retrofitting my Bedini Monopole to attempt the Large Wheel. I have a quadfilar coil with core that sticks out the bottom like John has. I remembered another thread some time ago where a user had done something similar to this and put a "piggy-back" induction coil on the extended core end. My induction coil is a small spool single filar coil of prob no more than 150ft of 23ga wire. After reading in the Ferris wheel thread about shorting one of the coil windings to itself to lower the inductance I decided to give it a go.
Upon shorting it on the running system there were semi-large blue sparks that popped at connection. Then the current draw went down over 50mA. and the wheel sped up as well. charging actually seemed to be faster. If I put my scope lead to this coil it has almost identical wave form as the rest of the Bedini circuit, but the spikes are noticeably higher. (edit here, when superimposed upon the regular H wave the spikes start and stop point are the same and peak is slightly higher than the source spike).
Or I can put this piggy-back through a bridge into a cap and run a small load with no losses to the original system. If you arent too busy could you explain the sparking of this coil.
Im sorry if this is a little long winded. But in a current thread by member Zooty titled SSG modification anomaly, I put one winding of a small Bifilar coil in series to the charge battery. The other winding of the bifilar i can generate over 200V AC. Put through a bridge I can run a small load from this mod. With it, current draw decreases slightly again, and there is not any decrease in speed or charging to the system. I know this is not directly related to this thread, and I apologize BOBO. The only reason I put it here was Peter mentioned shorting the coil. If I need to post this elsewhere like in the SSG mod thread I will."
I am not trying to take any credit for discovering anything. Part of this is Zooty's experiment, part is another users from a couple years back. I was just wondering about the sparks that are present when shorting the coil, and the fact that you can run a load with no apparent ill effect to the source.

Possible EDL/Meyers Absorber

JB mentioned Meyers in relation to EDL's magnet free energy producing device. I had this thought about it and after seeing Lasersaber's YT video showing a small current at the bloch wall on a PMH, I thought that this set up might work.

"Junior" 3GT

Hello All!!

Brent and I have finally finished construction on our "Junior" 3GT. We have all the magnets in place and are ready to start concentrating on the coils. The only parts of the construction that are lacking are the shelves for the two side coils and the platform for the center coil. We haven't picked a size for those and will place them once the coils are ready. We also need our timing wheel and re-gauging motor, although the re-gauging motor will be done well after everything else. We want to focus on one aspect of this machine at a time! As you can see from the pictures, it barely fits in our office. The construction went extremely smoothly and it is very well balanced and spins like a champ.

Thanks,
Scott

Scott,
That is a very nice construct--nice job, good looking work.

Hi Jeremy,

Is there any chance you have sorted out the coil interconnections in a schematic form to share with us? I sorta follow the textual description but am not sure how one would wire the slave coils with the master coil to be able to take advantage of this new method of switching.

Thanks for the post, it did make some sense to me.

Hi Jeremy
Looking at the magnet moving over the main coil where does the trigger pulse occur and do all three coils repel the magnets?

If I am following this correctly, I believe that the coils are offset in spacing from each other a bit. In other words, when a magnet is at TDC of the master coil, the magnets above the slave coils have already reached TDC of the slave coil cores are on their way out.

John Bedini states that all of the coils are in parallel. Since the magnets would be saturating the iron cores of the slave coils first, they would be creating a pulse of electricity through the master coil. To my understanding, this pulse would cause the core of the master coil to become somewhat saturated and the inductance(L) would drop. This might be what John Bedini was talking about when he referred to the use of a mag amp.

Once the mag amp effect is at its peak (inductance becomes lowest), the coils would fire from the half bipolar switch. The mag amp effect would cause the coil to charge in a low inductance state (Charging would happen quickly) and discharge in a high inductance state (High voltage spikes should occur) after the mag amp effect has diminished.

Eric Dollard has always spoke of the importance of changing inductance or capacitance with respect to time to cause the "synthesis of energy".

However, I am a bit unclear on the directions that the coils are to face. Since there has been so much speculation as to what is really going on, I've gotten lost in all of the non-Bedini produced diagrams.

Since all of the magnets on the rotor are north facing out, the only way that the two slave coils could create this "pre-pulse" of energy is if they were being repelled from coil being energized since they would have to have already passed TDC of the core. This means that the slave coils would have to be pulsing a north pole towards the magnets, and the master coil would have to be attracting the magnets with a south pole.

If somebody that was at the conference or that has a better understanding of what is being said here on the forum, please fill me in as I am just trying to understand what is actually being said.

Gene,

It's very simple, the slave coils are 1/2 the impedance of the main coil, as John has mentioned. This is his 18 AWG winding that he calls control windings. All three coils are in parallel. If you don't have the impedance right for the slaves, then you don't pre-bais the main coil with potential only.

Hope this helps,
Jeremy

Hi Jeremy
Looking at the magnet moving over the main coil where does the trigger pulse occur

The timing of the pulse is exactly at every 22.5˚ around the wheel. This is the timing everyone is looking for!!!

Look at the Red Dot at the back of the center timing axle. This is TDC for the magnet on the center coil

The (base three coil) hall timing magnets are evenly space 1 width apart. This is important!

Don't forget that there is first an overlapping pulse from the slaves! Again the slaves are creating the overlapped field of the first 90˚ in a purely inductive circuit. This will require shifting of the slave coils to get this just right.

and do all three coils repel the magnets?

As John K has said, there is minimal cogging! I believe that the asymmetrical alignment aids in preventing eddy current from the slave coil and slowing down the rotor. John B. also mentions using large cores to prevent eddy currents as well. If the noes are to strong, you will have problems and the core will be saturated and cause the switch to draw more current!

Hope this helps,
Jeremy Burnum

Thank you Jeremy
I found on my small replication that I get better results to adjust the timing a bit before TDC once the machine is up to speed. Then it slows down a bit and gives much better output. If I stop it with this timing adjustment and restart,it will spin in the other direction.
I also adjust the cap values to 6900uf as that give me the best performance on this setup. They discharge in less than a second at 24V.

I can also see now that all 3 coils repell the magnets and thus are all wired in the same way and polarity.

Don't you need to lengthen your cores on your slave coils? What kind of charging results are you getting now?

Jeremy,

Question - Are you suggesting that the 4 wires that are mentioned by JB are divided between the 3 coils? 2- 15 awg wires on the center coil and 1 - 18 awg wire on each slave (outer) coil? You seem to have a pretty good grasp on how all this works. Still trying to wrap my head around all of this.

The base coils are where Scott and I are now looking to focus our attention on our 6' "Junior" BFW. We are trying to gather as much knowledge as we can, as this is going to be the most expensive piece of the whole build. We realize that there is going to be several adjustments, but are trying to limit any costly mistakes. Have gone back and reread and reread lots of the posts here. It's funny how everyone's interpretation of all this information is all different. Scott and I read into a lot of the stuff very differently! HELP!

Also, how did you determine/confirm the hall timing to be 1 magnet width apart spacing? The pictures are very deceiving...even the picture with the strip of tape with all the markings!

Thanks for all your contributions to this thread! You have been a huge help with all your drawings. I am definitely a visual learner!


Thanks, Brent

Scope shots

Here are some scope shots of my small setup.
Once the rotor is up to speed and I switch it off, you see the generated sine wave.
On the 2nd photo you will see the on trigger pulse to the bottom, the reactive pulse that goes up to 26V before the cap gets dump and then during off time half the generated sine wave. This was timing on TDC of the main coil.
Now as I advance the timing till the trigger happens when a magnet reach the middle of the right slave coil , I only get half the positive going sine wave during off time before the next trigger pulse. Like Jeremy explained. Only voltage. The current is lagging by 90 deg and the next trigger pulse occurs before any current flows.
This gives me much better output and the rotor also slows down a lot.
Towards the end of the video you can see clearly how the sine wave change as I adjust the timing.
