Magnet motor in Argentina

[Jdo300]

There is always more than one stator magnet down in the gap,
so it is easy to lift the old one up.
If you want to lift the old stator magnet the next
one is already half way down, so it requires less force to lift
the old up.
So all in all the lifting back into the stator circle requires
less energy than you get from the rotor magnet torque.

I will show this in a few FEMM simulations soon.

So all the skeptics have not yet understood the motor concept.

Regards, Stefan.

If I may add to what Stefan is saying, if you can imagine a stator ring with 10 magnets in it, if they all have the north poles facing in, then naturally if you rotate one of them up out of the ring, the repulsive force from all the other magnets will want to force it out; and naturally, it would be hard to reset the single magnet back into the ring. It's like releasing a compressed spring and then trying to push it back again. But if we go with the idea Stefan is presenting, then imagine not one but maybe three stator magnets lifting at a time in a sort of wave fashion, where the middle magnet of the three would be lifted the highest (crest of the wave) while the two on either side of it would be half-lifted up, that way the total repulsive force is divided between the three magnets instead of just one.

Could someone who has tested the design tell me how far the magnet needs to be lifted to create the imbalance? Do the magnets have to be lifted one magnet length above/below the ring, or is just a slight deviation enough to cause rotation?

God Bless,

Tao, in my simple tests, I?d always found a resistance to push down a stator even with the next stators (3 or more) lifted if rotor is close to it. And more, the resistance is not a relevant function of close stators (almost irrelevant) but there is a strong dependence of rotor position. (it?s different for lifting). The rotor position is the first and more important resistance for pushing down the stator (it is what I observed). Then, consider the MAX-POINT when the rotor is just in front of the stator that is lowering. At MAX-POINT if stator is lowering (forcing it by hand in a "static" analysis), torque is very strong (even "violent", capable to do a completed turn alone if you released it with stators lifted). This is the max of torque that you have to get in simulations too. At this point, resistance has a maximum too, and the friction (in my model, a rough model without wheels in stators so far) brakes the stator. Then consider a little change from this point:
- Stator before this point, the resistance decreases but torque decreases too much because you are putting a stator lowered "before" the rotor. (Check your sims)
- Stator after this point, the resistance decreases, torque is a little bit lower (both are better conditions) but rotor almost "escapes" to gap, then the cap ramp have to be built with a very accurate way and tuning it (my model is too rough to it).
In any case, I agree with you it is better to have 2 or even more stators lifted.
I think we have to take a special care for building some parts (that is I learnt working with the first model): reduce friction between cap and stators, cap ramp shape (if variable, better for tunning), stators length and, in any case, variable point for lifting and lowering. Even can be good to use a few stators for a more comfortable work until the device works in this area properly.

in short for everyone else tuning in.... keep your "weel arm" (the arm that lifts you stator magnets up to create the gap)...... keep it adjustable so you can move it to the best location for fine tuning. a good starting point is v degrees (tao please fill in the *v*) from the center of the rotor magnets.

Hi.

Allthough this is my first message in the thread, I read ALL postings so I did do my homework.

I did think about the 3 lifted magnets: One going up, one up and one going down.
Does did not just bend the repelling ring, and not break it? If it only bends the ring, it is still a loop.

Actually, you can simulate the whole thing in femm, forces on stator magnets and rotor by arranging the displaced stator magnets as in Torbays patent drawing, instead of lifting the stator magnet.
