Experiments with a new HV coil
.................................................. ...............
I decided to go up in HV coil's turns so as to achieve accelaration from lower rpm. Oddly enough, in my setup it turned out that not to be the case.
I made a similar dimensions, same core, magnet gap etc HV coil wound with the same manner 0.3mm enameled wire at 113ohm this time.
I decided to mount it on the rotor next to the other working HV coil. (see previous posts for specs)
Findings
.................................................. ......
With this one even though of greater impedance and higher generating voltage (120 vAC vs 100 vAC) the accelaration effect failed to manifest in the >1100 region.
From rough estimations and assuming that it has a similar behaviour to the other one, it should go above 1500rpm to do the trick, (my estimation). I was surpised to see that.
First conclusions
.................................................. .....
The HV effect (accelaration effect) it seems to be an superficial one (as electricity production on a coil is) that happens on the surface of the iron that gets-magnetized/demagnetized constantly and NOT be totally dependent of the coil's impedance.
I now firmly believe (and i plan to prove it) that above a critical layer thickness over the iron core (that transfers the magnetic flux from magnet to windings) the surplus layers are just a burden (ohm resistance), contributing at "loading the HV coil and diminishing the effect.
On the other hand, for that critical layer height that there is an active magnetization/demagnetization action zone you must have an "sufficient" number of turns to easily initiate the event. The more, the easier.(more = lower rpm initiation, higher voltage generation,but lower oscillating current and vice versa)
You can now understand what i suggest by observations only.
But, i need you people to verify or invalidate my findings that so as all to be on the same side.
