Magnet Motor from Argentina, part2

[hartiberlin]

It is already a bit late and my brain is not working anymore....
How can we calculate the needed force (or torque) onto the rotor
to be a bit higher than the energy needed to press the stator magnets
back into the stator line ?

Okay, Power is = torque x 2 x pi x frequency= Force x radiusdistance x omega

So energy is Power devided by time,
so how can we calculate the energy needed for the rotor to press down
the stator magnet back into the line ?

Tao, I tried to remove a few vectors from your FEMM files and
it stays at 20 Nm, so that is pretty good !
It is probably this big, due to the bigger diameter in your setup !
This will automatically generate more torque !

You know that is an insanely huge amount of torque you are getting there! (almost 15 ft-lbs for us non SI people) What size magnets are used in the simulation?? It may be a good idea to use realistic dimensions for the magnets so we can get more realistic data.

The biggest question now is, if the torque times omega divided by time= energy from the
rotor is enough to move all the stator magnets up and down again and how much
energy is then left to drive a generator....

How can we calculate that from the simulation torque and forces output ?

I still think the torques in each direction will cancel exactly, and the thing is a closed conservative system- just as it appears to be.
(I don't want you to fail, I'd like to be proven wrong...)

Anyway, I have still been thinking about this idea and I came up with a simple and novel improvement to it. At least I think it would be an improvement.
I would call this the zipper variant. Instead of all the magnets going up, half of them go up, and half of them go down, alternating.

Normally the magnets oppose each other 'en passant' as the previous one lowers and the next one rises. In this version, you have one magnet going
down toward the base and the next magnet going up toward the base- then that magnet going up toward the base, and the next one going
up away from the base. The field basically looks the same to the rotor, but the stators are doing a better job of staying out of each other's way.

If that's not clear, I can draw an animation of this...
