Muller Dynamo

@Scratchrobot .I am sure a lot of people would like to replicate your work . But to achieve this , as always we need more info .Further to Arthurs questions . Please state number of magnets , their size , pole orientation . Are you using the fan motor to drive the rig . Coils . type and size of cores Litz or not , wire size , number of turns .If possible , resistance and inductance . How are the coils interconnected ? Do not underestimate the significance of what you have achieved . Speed up under load is the first massive step to overunity . If you fail to answer all of the above , then duplication becomes impossible .Thanks in advance .

I used 8 magnets on my rotor but that is not important, all magnets same pole orientation. Coils in series with eachother and the 1 ohm resistor. Don't know number of windings. I don't really have speed up under load but speed up when I place the second coil on the rotor. If I place the second coil I get more current and more drag but when I reverse the coil or place it at different spot I get less current and speedup. I don't know if it means something but when I place the coil exactly on the right place I get that Kromrey waveform. If this means something than the coil placement is very precise and then the coils have to be manualy adjusted one by one on a muller gen.

@Scratchrobot . Many thanks for sharing those details .Please confirm that the fan motor drives the rig and there are no drive coils .The bit about putting the second coil in the right spot is interesting . I assume that you are leaving the first coil in a fixed position , and moving the second coil along a circular path centred on the centre of the rotor ,Yes ,? If this is true , can you give rough estimate how far you need to move the second coil from its alignment with the first coil . to find the sweet spot please ?

Hi All,

My imperfect video of the bucking coils and effect on the rotor.

Lordy, I said 10 Farad, I meant 10uF for that yellow resonating Cap.
Schematic attached.

Hi K4ZEP,

Thank for for posting that video, your results are very encouraging. Tomorrow, I will connect my motor's coils in the bucking configuration and try the same test on it to see if I can get a speedup effect. If it is possible for it to work for air-cored coils, I will see it.

Also as a note to those who are making coils, if you want to get some off the shelf precision-wound ones, check out the inductors section of Parts Express. This is where I got my air-cored windings.
