Mini 12-coiler

[nilrehob]

I got my 12-coiler ready a few weeks ago,
unfortunately the time i can spare for testing is limited,
but i thought I'd start a thread for it already anyway



All coils are in attraction mode, dragging the magnet towards itself,
as repulsion punches a magnetic hole in the magnet it seems,
they all have welding rods as core

the rotor has got 13 magnets,
each coil has its own trigger-winding,
they also have two power-windings in series,
6 of them has a NPN and 6 has a PNP as in the schema,
with a zero, a -12 and a +12 rail



The second transistor on each coil is for shorting the coil when the magnet is leaving and the coil would otherwise be unused,
i have tried various trigger-sources from neighboring coils,
all with different results,
but i haven't found a proper one for them yet,
the best so far seems to be at the collector of the coil in opposite position.



(forgot to draw a resistor on the base of the shorting transistor)

Very interesting,
would you mind explaining it's basic operation and expected results?
seems to be the SSG/bedini cole modification and you have added a shorting technique to boost the charging effect? as well as give faster rotation? very nice. is it working well for you? can you add another rotor/fly wheel to take advantage of the torque?

The idea with the first circuit is to bounce the energy between the two batteries, this works, i think,
but not by reducing the draw but by increasing the speed without increasing the draw.

The addition with the extra transistors in the second circuit is to get extra energy back in a generator phase for each coil,
this one is tricky, lots of tuning is needed even without the shorting as each coil has its own trigger.

So far the speed is the best result
5000 rpm which is a lot compared to my previous builds

switching off the 6 PNP circuits and skippping the shorting it works like an ordinary multicoiler,
its still running fast but the efficiency is better at lower speeds
as the charging seems to drop on high speeds

It's a classy looking machine and one of those that many would dream of building

I'm perhaps thinking similarly to minoly...a second rotor attached to the first could power a generator. The main question would be about the power handling of the transistors. If they could handle the non free running of the rotor, then rotation speed would lessen and you'd have torque conversion to run a generator motor from it all. It might fix that excess of speed and also build on the output power.
It need not be a generator motor of industrial size, just something that brings down the rotation speed and yet also delivers power.
I do realise though that your tuning would probably be messed up.

Anyway, a video of this running would be cool

Hi there Nilrehob ,
Nice build looks like heaps of fun to play and test things with - you got skill . Thought id say batteries charged in one method and swapped to different methods dont usally last that long , they liked to be formatted to one type of charge so the chemical reactions in the battery aren't messed up . Be careful not to charge batteries from batteries that have been charged from a negative domain , say your charge battery reads above 0v on your oscilloscope anything that is created below that 0v to charge that battery is coming from a negative domain compaired to the batteries polarity - i just didnt want to see you wreck your batteries if you weren't aware of this . Cheers Jason

Thanks for the comments!

I'm not so sure about the battery charging problem being about negative energy as potentials are all relative,
if there is a problem it would in my opinion be switching between current charging and voltage charging
where current charging is the std way of charging and voltage charging is the "Bedini way" of charging.

Hi there Hob ,
Yes you are right with what your saying - with the tests ive done before with various circuits and motors ive found its the input batteries electrical output to the circuit and coil that is important to try and keep things recycling this is why John Bedini uses a cap to pulse charge for a recycle circuit - the cap converts the pulse. Ive done the tests on a Bedini sg and other circuits just to see by swaping the batteries and even charged them same batteries with another Bedini sg to top them up and all i found is that the batteries died after a week of testing them . This is another problem i ran into is topping up test batteries , once theyve been run down on a motor/gen after testing how do you charge them without damage to them and to run them on the motor again without long term problems . This is just some of my experience with charging batteries thats all - your motor might do something different - just trying to help Cheers Jason

looks great! Question, what did you use to build your rotor? Bearings, etc? Thanks in advance!

[Slider2732]

That is the fastest thing i've ever seen that didn't have an afterburner glow at the back
Great work, very enjoyable video demonstration.

The rotor is from a computer hard disk
the magnets are 13 small neos: height 4mm diameter 8mm

Nice work Hob,

It is ideal to do the tests we are doing with the Romero Muller generator.
See if you can achieve acceleration when shorting your coils, to make it selfrun.

I doubt that Bedini charging will show you any overunity.

Keep up the good work!

Thanks for the encouragement,
this is a test-bench for all kinds of crazy ideas
including shorting of coils
i haven't checked out your thread yet
lots to read to catch up
each thread should have an "executive briefing" kind of catch up area
