New positive proof of a working Newman fan motor charging a battery

[hartiberlin]

here's my attempt although smaller, need to findout how much current im drawing
Commutator might need to be made smaller, i.e the contact

the wire is .25mm diam @ 58 ohms

I might also get away from using brass commutator and just use the actual shaft.
also wind much more coil around it.

Well done DOM,
maybe if you have lying around a graphite brush from
an old motor commutator try this one as the one contact point at the commutator.
With this the sparks will get better.

Hi Stefan,

Thanks Mate, It's good to see replication from Oz.....LOL

It would be great to findout how many ohms and wire size chuck2na has used, Are you able to contact him to findout? 
That one took me 6 hours to make, just had to figure way to do it. At the moment the sparks can be seen, I'm using a 12volt 1.3A hour battery to drive it, ill check to see where its at , but i think its running down slowly.

I'll keep at it, because it would indeed make an interesting self runner.

I'll be looking at building a larger version as he has done it.

Kind Rgds,

Dom

Dom,
you can also put in series with the battery a small incandescent bulb and
see it light up from the RF bursts.
The DC input current won?t light it.
The Wattage rating of the bulb must depend on the current input amps
and voltage, for instance, if you use 12 Volts battery and have now
in running idle about  50 to 100 milliAmps input current, then try to use
a 3 to 6 Volts 3 to 5 Watts bulbs.
The RF bursts from the sparking should be able to light it up.

Regards, Stefan.

Just watching his vid again, I reckon wire size is .5mm diam, and im going to shoot for 200ohms if i can, or very close to it.

Just an observation to help others here with replication. So i'll be making another one.

Hi Dom,
try to get under 20 milliamps of avarage DC input current and
use more wire at 12 Volts.
You will need then bigger diameter
wire, so that with more turns you get the same DC ohmic resistance
as before, or if you now still have too low DC ohmic resistance of your coils,
just add more wire to the coil, so it gets a higher DC resistance.

But what avarage input current do you use now ?
Do you have an analog amp meter ?
Digital meters won?t display correctly with all these RF pulses...
