shortout the ampmeter , when you are done with measureing
and it might help to use thicker and shorter cables.

Your motor seems to run only on less than 5 milliAmps..
Maybe you have a better scale ampmeter, so we can really see the input power ?

Yes, try now to get a 1 to 3 Watts bulb and put it into series with the battery and shortout
the ampmeter.
Probably at this low input current you also have a very low RF output, so it maybe needs to go to
higher input voltages to see the bulb getting light up.
But it seems you have quite some nice torque already at the rotor axis, right ?


Many thanks.

Well it has now been running for 15 hours with the Amp Meter in place and the voltage has drop to 12.76-12.77 over that time.
I have now stopped it and removed the Amp Meter and shortened the wires, so we will see

I placed my other Amp Meter on it that goes from 0-1ma but the needle was hitting the end scale hard LOL, so like you say maybe around the 5 ma mark

I will try the 39ohm coil later and see how she goes also with the new Axle.

One thing to Note is by using BRASS as the new Axle I have got hardly any carbon build up at all, it just seems to self clean and drop away, But the sparks are very small.

There is better torque on the Axle than before but still easy to stop it with not alot of pressure.

Will have a play and update later

Here?s a motor I put together in the last few days. I originally put in on a lead acid battery and the voltage didn?t change a bit. Then I stuck a 9V on it and it has been running for over 8 hours now. The voltage is down about a volt but not bad for a motor of this size.

Nice work Eddy

By straightning your Axle and balancing it a bit more will help loads.

Good Stuff

Have now rigged up the 39ohm Coil wth the new Axle and it spins at around 1700 RPM and gives a nice spark.

While altering the tape I was pulling 100MA and the battery dropped to 12.69 Volts. After fine tuning it I got the current pull down to 30MA as shown on attached video. The voltage has now creeped upto 12.72 volts as shown on Video.

Have disconnected Amp Meter now and will leave it run for a while.

Gonna pop in the Car and see if I have a 12V spare bulb, but will probably be around 5 watts.

Cheers

Sean, you can also use a lower voltage flaslight bulb, as you always have the coil as a pre-resistor in series.
You have to use such a Wattage bulb, that it will not light up yet, when the rotor is standing still and makes contact.

Thanks Sean! I watched your video and was impressed by the speed you are getting. Obviously, careful and meticulous workmanship has paid off. Very nice work.
