I am talking about old type ignition coils from cars with distribution caps. See the picture.
I did not think about your approach, to use the low voltage winding for moving the rotor and high voltage winding to collect the high voltage. I do not know if it works. Please take a look at the circuit in the attached picture. It is based on the pictures uploaded by mr. Marius.
My english sucks but I will try to explain as simple as possible. I also advice you to take a pen, a paper, to read this at least three times and to write down everything in your way, or else you will not understand everything 100%. You have to understand that this is not a child play. If you think like a child and you do not take this serious, there will be no success and we will all keep spinning around our tails for years, like cats and dogs often do.
Now let's push the science. Here's what you have to do:
-> You move your rotor in your usual way - the same system you are using now. Hall sensors or bedini styles, whatever you use. One or two coils, does not matter. What is important - to make that rotor spin as fast as you can. Please draw your rotor on paper with your system for spinning it. Do not add anything yet.
-> to collect the output voltage, you use two additional coils from automobiles. Or only one coil. Experiments will reveal the mistery. Anyway, you will get A LOT OF HIGH VOLTS so watch your hands, it really hurts. Those high voltages are of no use because it's low amps, but we must remember the formula: P = U x I. P = power in watts, U = the voltage, I = intensity (amps). You get some watts but the voltage is high. So we have to reduce this high voltage.
-> Also, in all your experiment you noticed that when connecting a load, the RPM goes low. That is because of the Lenz force, which is B x I x L. B is the magnetic flux between the magnets and the ferrite cores. I is the intensity in the coils (how much energy is sucked by the load). L is the induction value of the coil (in Henry). I understand this sounds like "chinese language" but this is needed in order to get the things done. Romero found something he called "sweet spot". He added some magnets on top of his coils, to reduce that force. And he managed to influence the "B" (magnetic flux) in the coils, in such a way that the value of the formula (B x I x L) got closer to zero. Hard work to do that. I had a lot of talks with him and he agreed that mathematics is not his close friend.
So we need to play smart. Modifying the flux in the coil is hard stuff. We need that "L" (induction value of the coil) because this is how the coil is made. What we can EASY modify is the "I" (intensity).
We have big flux (B) - because of strong magnets, and we need that. Weak magnets sucks, no help here. We have big "L" (a lot of copper wire turns in the automobile induction coil - to get high voltage) and we don't want to change that. We have a small intensity (amps) because the copper wire is extremely thin (thicker wire = more amps and bigger coil, thin wire = less amps but smaller coil) - less than 1 amp, let's say 0.000y (we don't know the value of y). We multiply something hign (B x L) with 0.00.... and what do we get? a small result. Which means a small Lenz force for "slowing" the rotor.
How do we calculate the power (watts) the coil provides? P = U x I P(watts) = 10000V x 0.000y(amps). Some of those "zeros" from the kilovolts will go away. More induction coils adds more to the output power in watts.
Please add one (or two) automobile coils on your drawing.
-> If you connect the output dirrectly to a load (bulb lights) you high chances of burning the induction coils. They don't like that. Also you cannot connect any electronics. Bad idea. We have to transform the power - same watts but with low voltage, so we can make good use of it. This is where the microwave transformers come to help.
More mathematics. I know, f**k maths, numbers and formulas, but that's the best friend we have right now, and in schools they do their best efforts to make us hate it, to keep us stupid slaves who fill their bank accounts.
Once upon a time there was a smart man called Nicolae Teslaru (best known as Nikola Tesla) who was born from romanian-origin parents (I'll smash your face if you say it's not correct
) and he invented the transformer. He also said that in ideal conditions, the same watts you put in the transformer in one side, are extracted on the other side. We do this using the microwave transformers like in the picture below.
If you connect the ignition coils dirrectly to the transformers, you will have a high chance of burning the induction coils, so you have to discharge that voltage using a spark gap. At this time I cannot tell how many transformers are needed. One, two, maybe three. You have to expect for the coils to burn so be careful. At the output you will get the same watts, but they are made from a different I (amps) and different volts (V), but the output P (watts) is almost the same as the input power (you have some losses in the transformers and some influence from the distance in the spark gap).
Please add the spark gap and the transformers to your drawing.
Please take a look at the picture.
You connect the high voltage sides of the transformers in series, that's because you need to collect as much voltage as possible. Intensity (amps) in series circuit stays the same, and we need to keep it low or the coils will burn - that is because the heating is U (voltage) x square I (amps) x t (time).
You connect the low voltage (220V) sides of the transformers in parallel, that's because you need to collect as much amps as possible. And here is where you connect your load. The induction coils will do their job, low lenz force, maybe acceleration under load, high voltage so watch your hands. The transformers will transfer the precious watts to your load. As soon as you get acceleration under load, you can start thinking romero style: measure the output volage, reduce it again ( let's say a modern PC AT/ATX power supply which supports input voltages between 100 and 230V) and use this to power the system.
Also, in the picture I draw the magnets like crap. You use your own magnets setup (please draw it on your paper). Test with same poles or different poles orientation. Be careful how you connect the coils. If you have the same orientation, the beginning of one coil goes to the end of the other. Also be careful how you connect the microwave oven (MwOwTraf) transformers. The beginning of each coil is marked with a thick dot in the schematic.
Question: have you ever play, or seen someone playing with a gasoline electric generator? if you connect load, the RPM of the gasoline engine goes lower. That's because the generator inside has low voltage and high amps (after reading this carefully, you will understand there's a high lenz force). I wonder what happens if the generator inside has high voltage, low amps, and the output energy is reduced with transformers? First thing I am thinking is a very expansive generator (extremely dangerous if it comes from a chinese manufacturer), which... does not go low in RPM if a lot of energy is sucked out of it.
My project consists of 14 car induction coils (for collecting voltage) and 4 car induction coils for moving the rotor. The entire electronics consists of vacuum tubes, to work with very high voltages (and low amps, so low lenz forces on the rotor moving circuit, and also low heat losses). The project is divided between papers and some boxes with parts, ignition coils, vacuum tubes, microwave transformers... and school sucks. Don't try this idea (yet), please use your own rotor-moving-system. Pictures after the weekend.
Warning: high voltages. Use some thick rubber gloves if you want to touch the monster while powered, and be extremely careful. Nobody you love have a wish for the priest to come to your home.
If you guys need more details please let me know. I will do my best for help.
