Bedini replication in Germany

Hey Shan,

If you haven't already, check out Tesla's one-wire "System of Electric Lightning". US patent 454,622.

And just to stay on topic - Albert, are your coils wired up as master/slave arrangement or are they three separate circuits? Master/slave works better IMO, it's also easier to tune and will charge your batteries better.

Cheers,

John

Hello friends,

thanks for the tips- I would like to use the bigger transistors, but have not found them so far here in Germany.

I have worked out the vibration problem - needed 2 grams of extra weight on one side of the rotor. And a wooden cross bar to stabilize the whole thing. There are resonance problems at certain speeds. I also used some rubber dampeners from an old cd rom drive to get rid of the droning noises, this way I can run the thing without hearing it all over the house.
Right now I run a slow test - changed the gap setting between rotors and coils- so this way the thing will run at 700-900 mA at 350 rpm. I charged both battery banks at 12 volts -put in 15 AH into both of them. Lets see how long the running time will be until both bats are down to 12 volts again.
The cap bank/ back popper system also continues to intrigue me. I will rework my first bike wheel machine to have the axle rotate and then make another coil for it. it should run on very little current. The bigger machines are probably not too good for this anyway.

Shan, my coils are all running from the same trigger. I would like to try a separate coil for the trigger - it can deliver more current. I also would like to try having a four coil arrangement with two coils between magnets and two coils facing magnets. Bedinis "double decker" machine has that but they are all firing from the same trigger. He says this way you can get torque out of the rotor.
gandalf, thanks for the tip on the batteries. I think - like you- that the gel cells might not be the optimum- mine are old anyway and I would like to try new ones. but they are too expensive for me at the moment. I  have not tried wet cells at all so far because I do not want to have that mess in my shop. When summer comes, I will try to move one machine to my garden shed, there it can make all the mess it wants to make!
I thought about doubling the pulse rate by having the above setup and running it off two different triggers. So there is a lot to try still..all these setups are prototypes anyway.

Please keep me informed! ren, what do you use for coil cores? we are talking about laminated cores - rectangular in shape to be the width of the magnets. what do you think?

Hey Albert.

I think youd find the square cores would perform very similar to the round ones. I could be wrong though. My core is circular and is the same width of the magnets I use. I had good results when the magnets were smaller too. I brought 5 kilos of R60 (Comweld high test, equivalent of R60) and it seems to work well for coil core. I'd be happy to part with some if anyone is willing to cover cost and pay for postage. I can cut it up to the length you need to make postage easier too. It was $60 bucks for five kilos, and theres no way Im gonna use it all this century.

Albert I think it would be interesting to try a pick up coil as your trigger coil. You could wind very fine wire and try to get the quickest switching time possible. Alternate firing will give you a little more torque but not as good charging IMO.

Thanks ren - I read the post and I see that every day some more information seeps out.

RESULTS:

I ran the 3 coil machine for 4 days continuously, switching batteries about every 10 hours or so. I tried to make the switching over as quickly as possible without stopping the machine.
Before doing this, I charged both battery banks with a normal charger, I put in 15 AH into each one, makes 30 all together. Both banks were at 12 Volts before charging em.Voltage at rest was 12.580 before the test and about 12. 126 Volts after the test.
I have then set the machine not to its normal sweet spot but to a much lower speed. It draws -- here it gets difficult!! My analog needle meter shows 1.5 A - the true RMS digital ammeter also. the clamp ammeter shows about 800 mA. I tend to think more along 1 to 1.5 A.
Ok now- lets say we ran for 96 hours at 1.5 A. Makes 144 AH Output. At 800 mA this makes 76 AH output. both are way over the combined capacities of the batteries. Anyway over the 30 AH I put in at the beginning.
the lowest voltage on one of them was 11.885 volts. At rest both banks were still above 12 volts at the end of the run. All the while the rotor turned at 450 rpm.
If that is not O'U, I don't know. If I had pulled the cells down to 11 Volts, I would still be running today....
I notice that the radiant charge has a tendency to dissipate quickly on the cells I use. I had to keep at it nonstop.
I think the problem with the battery switching is that people tend to force too much current into them while draining the drive batts too quickly. I ran a test with the machine at full blast drawing about 5 A on the batts. The charge battery would go up very rapidly, then collapse to the voltage I had before I started charging when I switched it to the input. By running the machine slowly I seem to be in "nature"s curve" as JB would say. Also, the type of battery seems to respond better to several short pulses in a row. At my setting, the machine gave 4 pulses, then a pause, and then 4 pulses again. Looks like the signal of a RC transmitter before modulation.
I really think that another problem may be that the batteries seem to respond well to a pulsed charge but not to a pulsed DISCHARGE. If one of you has a really big capacitor bank, try hooking it up in parallel to the energizers input to see if the battery lasts longer when the pulses are smoothed by the caps.

Please tell me if you find faults with my measurements - and my reasoning!

 Thanks for posting some measurements  . this will give me some more comparison  numbers to  use against my own numbers.  I have ran   measurements on  the setup I have built and have measured  the amp cost to turn the rotor and  amp outflow to  the charge batts, I get better numbers early in the morning  on the first couple of spin ups.  the cost in amps on one good test was  2.1 to 2.2 amps at 23.21 vdc ( I went up to 24 volts to drive the rotor to get more speed while using more adjustable resistance on the trigger line ) to turn the rotor.  Then out of the  return charge line to the charging battery  I read 1.43 amps at 12.75-12.8 volts  this was not good enough so I took 1 line from each coil  that did not have  the trigger line in them and I built a bridge rect. out of 1n007 diodes  and ran it  through a spring switch then into a  set of 6- 30 vdc , 160,000 mfd computer grade capacitors  and spun  the rotor up again . this time I also pulled  2.0 amps at 22.6 vdc out of the 2 coils while I held the  spring switch closed which I loaded into the capacitor bank . If I left the spring switch open the line buildup would  get to 23 volts and when I closed the switch to let the buildup into the capacitors I would get up to 8 amps for a couple seconds until it bled off into the capacitor and then it would charge at a 1.4 to 2 amp  continous rate. I figured this was great because these 2 lines that were feeding the caps had no voltage input other than what they picked up   through the coil ( induction transferrance?)  while it was running the rotor . almost something for nothing , but I do not thinng so  yet?   So now  the system has 1 battery that is giving energy 2.1 amps @23.21 vdc,to turn the rotor and 2  charge circuits  that give  1.43 amps ( through the transistors) and 1 that gives  up to 2 amps continous through the coil;s using inductance. . A lot more work to do and I really want to try the cap at the drive battery you spoke of. thanks again....fr.. rick,.( I hope this is understandable  description  I was rushed to get ready for another 12 hour night shift.)
