Hi Sky
Sounds good,but remember you are drawing very little amps with leds,what is it like when the coils are shorted?

Hi folks, thanks for the replies and interest.
Hi Peter, Of course yes thats not much of a load but I had already tested with shorted coils and still no input increase just failed to mention it yet until someone was interested enough.
Hi Harmonic, right now I'm testing only with the 2 coils as shown in the cad pic posted with 16 rotor bolts. the coil cores have the same size steel bolts as rotor and the 2 stator coils use 24 awg wire, each coil is about 6 ohms, and there is a stack of neo's at the back of each coil-core of 1" dia. X 1/2", when coils are wired in parallel max shorted amps are 100 milliamps, open circuit voltage in parallel spinning by hand is 2.5volts, when using a drive motor at 12v at about 800 rpm with about 1.8 amp input, keep in mind freewheeling without magnets attached is only 10-20 millamps below that input which means it has low drag, the volts are just over 5 volts at around 800 rpm. What is really interesting to me so far beside the no lentz drag is that the max amps ramp up at very very low rpms compared to any generator I've ever built or know of and I think it is because there is not a second source of moving magnetic field on the rotor to interfere with the coils generation, akin to no counter emf reluctance motors.
hope that helps some, any more comments or questions are welcome. Understand also right now I'm trying different things to maximize output then later it can be scaled with many more coil-cores for more output.

Hi Sky
Nice simple,straight forward setup,been trying to compute your numbers,not my strong point,to say the least,but I don't think there are enough yet,but I'm sure you will give them in the fullness of time.Look forward to the next episode.

Hi folks, just thought I'd show the 2 coils so far powering 12 leds spinning by hand at about 500 rpm.

Hi Sky,

If I can continue on with your thread? I have changed the design somewhat but with the magnets on the back of the core still.

Results:

1) two cores and coils, single magnet on each core, no back block...

   Coils in parallel... 9 volts DC @ .1 amp for .9 watt output

2) Same as above but with the back block installed
   
    20 volts Dc @ .2 amp for 4 watts output - approx 3.6 watt draw on PM

3) As above except two magnets each core (magnets are 1 inch dia by           
    1/8th inch thick)

     25.34 volts DC @ .25 amps for 6,3 watts output - 4.8 watts on PM

4)  as above except three magnets each core, an added brace to the riser,    and a slight reduction to the gap...

 33,4 volts DC @ .34 amps for 11.3 watts output  - 7.2 watts additional draw on PM (input)

Construction: the cores are up off the aluminum plate on 1/4 inch phenolic pads with a phenolic joining strip across the tops of the cores. The cores are just MOT laminations.

Conclusion:

Lenz is still apparent but possibly reduced?

However, there are 14 watts core drag I must add in here which defeats the purpose rather quickly. 20 watts cost to make 11.3 watts
