Hi Gotoluc and EMatrix

I wouldnt say its OU since what I left out is high up the motor goes in amp draw when the coils load (lenz law lugging)
also when the motor lugs RPMS go down, so the generator coils dont put out as much either at lower rpms....romeor got his to SPEED UP under load - thats nice thing to happen eh...

those numbers are how I like to measure how powerful genrtor coils are, or can be, very quickly - that is to measure amperage with direct short with ammeter, and measure voltage maximum with no resistance at all so you have idea of most voltage possible.,,,then general rule of thumb is that when you put resistive load on the coil too, its going to be half the amps and half the voltage with the resistance...

the way (one way) to "make it" OU is switch-short the coils at the peaks, put this into DC capacitor with no resistance on it, then dump cap to load when cap is disconnected from coils...now there is no lenz lugging of coils, and voltage in cap goes way way up very quickly, and the amperage coming from cap to load will be greatly dependent on how high the votlage is in the cap (also the resitance of load, pulse width frequency etc etc)

- for example 100V in 1000uf cap into 10 ohm load will have lots more amperage as compared to 20V in 1000uf cap into 10ohm load with same pulse width and frequency.....

I'm pretty sure now that it doesn't matter wether it's a Muller or Romag or Adams or Romero's replication, to me the speeding up under load is happening because the rotational speed of the magnet ensures that, at a critical RPM, the magnet is out-of-the-way quickly enough to beat the rise time of the EMF in the gen coil, there is a certain window of opportunity where the Lenz effect would actually assist the rotation.

My magnetite powder has arrived, tomorrow i'll get the epoxy to make the cores plus the wire for the coils and i'll look into it.

Hi DeepCut,

can you tell me where we can obtain magnetite powder ?

Thanks
