The Ossie motor

[Magluvin]

hey Jim

Well if the lil coils affect it that much, of which I am surprised, then I wonder if the could block a magnet as a stator as well.
The thing is, if the fine wire pu coil is enough to stop the motor, then it should use very little current to block a stator magnet to get motor effect. And the regen developed in the coil after the pulse should be a lot.

Other than that, Ossies setup seems to be the one to work on.

Sorry for the no go on that.

@mags It's just toooo damn tempting tho. I'm seeing all that energy not being used. Current config of 3 pu coils (seems to wrk better than 4) running on 6 x d cells at 5.5v .02A at 2000rpm gets 4V. Haven't measured current yet but it seems a shame to just throw it away. I will pursue Ossie's new motor but keep the pu coils from these torches. A weird thing tho. If I angle the neg side of one coil close to the rotor it doubles the rpm and the amps drop.

Hey Jim
Try the pu coils btween the drive coils. It looks like you can squeeze them in

I'll try again. Hard to keep them stable tho. Have to try a diff mounting. Lost a couple of good coils that way :-)

Oh  you already tried?  oops.
If you get some plexi strips like 1/4 in. , it bends nice with the heat of a torch or hot air gun. It makes brackets easy.
I have an idea I will draw up later, I have to go to work.  But if you use a small u bolt and wind a coil on the u and have a bracket or bridge and have the open ends of the u bolt aiming down, 1 bolt end just above the S pole and 1 just over the N pole. The bolt will attract the field of the mag upward and it will generate voltage.
Or you can do it from the top and bottom so there wont be a wobble induced in the rotor.
So you have it doing 4000 rpm?  This is good. I would work on more speed as you go, but if the gen brings it down to to even 1000 rpm to get some decent output, retune the motor at that point. Loads change things so it has to be re tuned .
