I think you should realy try again your Newman motor recharge your batteries, but use like Stefan say cooper commutator and graphite brushes.

Good luck whit your projects.

Hi Michael

I do not have copper rods, only brass. But see the post above now trying some graphite brushes.

Cheers

Okay dragged out one of the coils and manged to get some brushes out of a old 240V motor to try.

Much better sparks now .

Here is a video to show.

I messed around for ages with tape on the axle trying to get the timing right then had a brain wave about bending the axle a little so as it rotates it touches the brush and fires.

Interesting thing was the Battery was 12.08 Volts when I started and I have left it running for the last 15 minutes and the battery reads 12:09 volts. I have seen this before but it has ended going down more than up, so will leave it running and check again later.

I also have some flat AA batteries here and will tape them together later and see if they charge or degrade even more.

Yeah! Good news! Back in business!

AA-batteries will maybe don't work. They can't catch all of those hight volts and hight negative back-spices. But it could be worth of try.

Hi Sean,
well done,
but your coil is much too small.

How many Kg wire do you have ?

You need at least 10 times as much
and thus several times bigger wire diameter to have
about the same ohmical resistance as you now have.

That will give you also 10 times higher BackEMF
and thus more back current spikes.

Or just test  something I still also want to do soon.

Take e.g. 5 high voltage caps with  100 nF and make
another coil with maybe 1000 windings
and make taps after 200 windings each and
put one cap there.
So finally you will have a multiple LC coil
with 5 x 200 windings in series and  1 cap bridges each
200 windings.
So basically you have 5 x LC circuits inin series
from each tank having a L with 200 windings and  cap with 100 nF.

Then use this as the Newman coil.

This enhanced capacitance of this new coil
will give you much more energy storage and
the back spikes will be much bigger again
and much more power will come out and
this will be a way to reduce the amount of copper
wire needed for a Newman motor.

It really depends on the parasitric capacitance of the
Newman coil, how much back spike energy you will be able to draw
out of it too.

Hope this helps.

What? Should there be much of THICK wire? Not TINY wire? Damn it! I did buy 0,2mm wire, and it is tiny! Now I will be not able to capture back-spices=no OU?

Hi Stefan

The wire is 0.25
The Coil I used here was the 39ohms one.

I still have the 200 ohm one that I have not tried with the brushes yet. This one is 2000 winds of 0.25 wire around a 80mm tube and is exactly 200 ohms.

I like the idea of winding the caps in series but that is gonna take some time

Cheers
