Hi everyone!

I just want to share this information to you. In the picture below there are some of my coils that i've been playing with. The coils 2,3,4,5 are giving me around the same power output when i tested them as gen coils.
I just put one driving coil and then tested the coils one by one. They all are giving me around 3W output but the driving coil sucks in 7W.
The coil nr.1 is giving me a little more than 4W with the same 7W input. It is the only coil that i have that gives me a little more power out regard the other coils. I can not understand why couse i did nothing special to that coil

Hi Marius,

i think coil number one works best because :

1. The coil's width is roughly the same as it's height, square cross-section is best for power generation.
2. The wire is fairly thick (0.5 mm ?), so good for current.


All the best,

DC.

Hi Gary!

You may be right! But i tried to replicate  coil 1 with no succes. More current means more lens and this means more drag. For now is a little mistery why is working better

Hi Mairusivic

The video of the speed up from the aircores I havent seen yet - thanks for reposting this it is great to watch..

a few questions:

How many magnets in the rotor of that?

Are the magnets arranged N-S or all-N??

It is very interesting the way it doesnt work unless the motor-circuit spins the rotor clockwise
and at same time if you use the gernator-coil pulse circuit as motor-circuit,
it would be spinning the rotor counter-clockwise - and this relation in spin directions if both circuits happened to be used as motor coiol circuit is how it must be to get the speed up with the aircores. (thats how I understand it in  what you said in video)

Did you just swtich the polarity of the motor coil circuit to reverse direction??
and same for the gernator coil circuit "if" it was to work as motor coill circuit?

Or to change the rotation direciton, did you actually adjsut the timing itself??

If you change the polarity of the motor coil is all you did, with no timing-adjsutment to reverse direction;
then that means alot as to why it works as it does - since lets say the motor coil is attractive-pulse.....then the genrator coil circuit "if" working as motor coil circuit in the mode where it gets speed up - would be in "repulsive" mode of the coil to the rotor magnet...

In repulsive-mode to motor coils, and with aircores, having the magnet directly acrss the coil lined up "square" to it, is the most speed and power with least draw for the pulse-timing to be at...but for attracive pulse with aircores, having the rotor magnet OFFSET with center of rotor magnet near edge of coil gives the best speed and power and least draw so ther eis some time to pull the rotor magnet to the coil......

so knowing this, you could estimate the timing of that generator coil circuit pulsed into load that gives the speed up - in relation to the timing of the motor coil circuit......

(this means the time to pulse the gernator coil circuit is when a rotor magnet is directly across the coil with no offset at all...this makes sense, since that is when the coil could b pulsed "either way" and the rotor magnet wouldnt care which way to move if is perfectly squared up...so no lenz since lenz doesnt know which way to lug it)

In the mystery-5W coil, that works better than the others - is that and aircore or does it have a core when you test it?
Is that 5W in a "pulsed test" into a load, or is is a "lump resistive load" across it??

Hi konehead!

In the speed up video i think i just switch the polarity of the coil but i'm not sure( i have to do that test again). What i think is happening is that the cap is beeing
charged and this creates lenz. By apllying a load , the cap eliminates some energy alowing the rotor to speed up until it hits another equilibrium point. I also remembered
that when i took out the cap, the rotor speeded up normaly and the LED was even brighter. So, the cap is doing the trick and there is nothing extra here. Is just fun to see it accelerate under load.

My mistery coil has  10mm/20mm ferite core and is giving power with just a load across it. I'll make a video and show the differences between different coils.
I have another coil that produces even more power ''unloaded'' and when i short it , lenz is not so powerfull
