Flux density altering/No lentz/Low cog generator

[SkyWatcher123]

Hi Peter, thanks for replies and compliments. I have some ideas on how to improve the design and hopefully get more output. Though thus far I am able to light up 12 leds and could probably light more, with the 2 coils in series spun by hand, these are the smaller christmas leds.

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

Hi Sky
Good going,pleased to see you are still at it,it will be nice to have some numbers, that will tell us what it's doing,maybe soon?
Good luck,happy hunting.

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
