Newman machine replica

[Starlite]

Thanks NerzhDishual,

It is basically what I have made, I have made a basic commutator and it works fine without me holding the wire. From the patent as a guess I might try a bifilar coil instead of overlaying the coils which I cannot get to work when loaded. I have not tried the battery, however I have managed to measure the current and as I suspected it is close to 1/2 an amp max, I also measured the voltage across the commutator which was around 12 volts max (nothing astounding). This is still very good as it is only pulses once per rotation. I will try to measure the speed versus voltage. Let me know if you can provide further insight.

Hi Starlite,

I have taken the time to build a simple commutator and, now,  I do not use my hands anymore for that .
You said you drawn 1/2 amps max. Sounds too much to me.
With a mere 18 homs coil and a 12 volt bat I do not draw more than 60 milli amps
(according to an old (Soviet) digital   analog [edited] amp meter 'ranged' between 0 and 60 mili amp).

Now I'm buiding a more  elaborated 'Newman-Type' motor with much more turns, and
bigger magnets. To me it is not yet a genuine Newman machine.
The millboard-whisky-can one was just for the fun...

When I get my camera, I make a footage.
So, more to come soon.

Best

I've just finished rewinding the coil on my replicated newman motor, it now has 2490 turns of wire measuring a total of 150 ohms, I've got a couple of flagging lead acid gel batteries which I will connect it to and leave over night, will take voltage measurements before and after obviously.

btw, the wire was removed from the secondary coil of a microwave power transformer.

Here's my new commutator. It needs alot more work.

Hi I am new here, this is my first post and sorry for bad English :p.

I have One question:
When I take my device under current the magnet will turn for 180? degrees, because then the magnet is there where it wants to be (North to South, South to North...). But how it will beginn rotating? Do I have to pulse the current so that the magnet will use the kick to rotate for over 360?, I tried it but it did not work (too weak magnet?). Or do I have to use a commutator?

I use 2 kg wire of 0,4 cm thickness.

Hope you can understand and help me.
