Hi guys!
I found an usefull thing (maybe you did too so if you did please ignore this)
Every time i connect i diferent load to the same gen coil, i have to adjust the position of the hall sensor for best output under load

"if the load is increased then all setup must be changed."

This is crazy, you know your getting close when you're starting to play with strange runaway effects.

I seriously wish you had a full battery of decent scopes and measuring equipment, it may be that your voltage isn't dropping, but that your meter is having trouble measuring the VAC in the coil accurately.

hi Mariusivic

I assume your meter is reading voltage in AC setting (DC is not going to work at all) and assume also your 8 rotor magnets are all facing same polarity too....so the meter isnt really reading a "pure sinewave AC"  it is reading the slanted and askew and choppy "AC" wave that the all N rotor magnets make and at certain speeds and rpms it will be sampling this or that volts that happen to "resemble" a standard AC pure sinewave that the meter has the time and possiblility of actually sampling...
thats why when you slowed it way down with a load, the voltage went up  - which you know "isnt right" - the meter now had much more time to make its what-it-thinks-is-AC voltage samples since the rpms slowed so much.
If you had rotor magnets that were N-S-N-S-N-S-N-S then you meter would see a much better AC signal and reading in AC  would be closer to what is real just this as an example - (but I'm not suggesting you change yor rotor magnets at all - it works great as is)
So with all-N magnet in rotor the meter just cant read it correctly and does all sorts of confusing things according to what it can be sampling for those short bits of time it does its sampling.
If you really want to see what the voltage coming out from generator coil really is, during loading and all that, put a FWBR on the output of the genrator coils to rectify to DC, and a DC cap too across the DC out of the FWBR too, now you meter in DC setting should behave in a predictable way and be fairly accurate...

however the diodes in the FWBR might mess up the behavior of the speed-up event you get when shorting and loading - which is the great thing you have done -

so use that meter and FWBR and DC cap just to get an indication of voltage you have coming out of coil for general knowledge, or if you want to do some lump-resistive load tests to figure watts using ohms law, but dont use the bridge if it messes up the speed-up event you got a couple videos back...

I see that a "regauging" magnet behind your motor coil really drops the input amps of the motor-coil input in your first video ( I get same thing too) - Have you got any good results with regauging magnet behind the cores of the generator coils yet?

Hi Konehead!

I've just finished doing the measurements. With my metter on DC i could see exactly what's going on. And guess what? The voltage behavied exactly like in the video , only this time in DC. Also i connected an analog metter and the readings were the same as the digital one.(so my ultra-supa-cheap metter is right  )
From what i observed about the biasing mags; sure there will be a point were i could use the mags behind the gen coils but for now i stoped using them. Yes, they increase the output but in the end , the input power increases too.
