My first Neman motor

[detrix42]

UPDATE:

I now have 24-9V batteries. With all in series I get about 208v (due to the first 12 being used batteries). 4th video up on youtube:   http://www.youtube.com/watch?v=L4QF5LqqlA0

WOW.  Still a bit buggy, but getting there.

Ok wow. video #5 done and up on youtube.  A full 10 minute run with 2 sets of 12 9V batteries. And I have some torque. Wow.  Now to get another spool of wire for the top coil.

Thanks for all the help

Hello.  Today I ran my Newman motor for an hour. With 2 sets of 12 9V batteries in parallel. It ran for the entire hour, though a few times it seemed to slow down, but pick back up.

one issue I have now, is that the coil warmed up.  Nothing to hot, just warm.  Definitely to much current. So this is not a Newman setup.  I ordered a spool of 26awg wire today. I think I need to redesign the commutator.  hmmm.

Just a friendly warning, centripetal force may cause your magnets to fly off - you may want to secure them, unless you have and I just haven't seen the screw heads on the ends.

You may be able to use something other than a circular coil, ..you could bring the sides in and crate a square one - though this would mean rewinding that wire, it may increase the number of turns by maybe a dozen or so and the clearance may go down, if you do this, it would be easy to separate the coils over the top, you could just hinge one side and sandwich them over the axis.

The magnets are very strong neodimium, with 96 lbs of attraction on their surfaces.  It will take a few hundred more RPMs to get them to fly off.  I love these magnets.  I like to put one on the back and front of one of my hands and feel the squeeze. Thanks for you concern though.

A square coil is being considered.  But will be after a couple of other round type. I ordered more wire, for going on top, but my current set-up needs to much current.  Need to re-think somethings.
