That is cool

Cannot wait to get to the Video where he explains his coil a little bit more.

Are the two round Magnets held in repulsion or attraction?

Cheers

Sean.

Looking good maxc-

Mine is so ugly I wouldn't dare post a picture of  it in it's present incarnation lol! but your is looking very nice indeed.

Stefan- thanks for the information. Yes, I see that now I am drawing too much amperage. My little motor is currently drawing around 4-500 milamps without a load. I need to wrap more wire around it yet.
Other questions I have are - is what strengtht should the magnets be? is stronger better or not neccessarily? and finally how much distance should there be between the coil and the magnets?
I hope too that NerzhDishual will be so kind as to copy and post that latest video.

thanks for your help

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.

Attraction of course,
it is just one big magnet to the coil !
