Magnet Motor from Argentina, part2

[georgemay]

I already explained exactly how to implement a 0 force situation, meaning 0 force needed to lower and lift the stators. My COMPLETE explaination is on the last thread and it outlines exactly how this is done. It has to do with having 2-3 stators ALWAYS lifted.

How much of a distance magnets in your design should go up? In the femm simulations they are not even there.   If they have to move a little then I agree about the Zero Force.  but then simulations are not so true.  If more apart, then 0 force may not be there at all. 

Here is the explanation:
while magnet is going up it is leaving field of lower magnet next to it.  This field becomes weaker as the magnet moves up.  Next our moving magnet is trying to enter the field of the magnet which was lifted before.  That field is starting to be more and more stronger while magnet is moving up.  So where is that zero force?  Somwhere in between, but not at the high point.

I have an improvement aready tested.  and it works, but I've been told to shut up because you are trying to replicate original design

Hi Tao,
if you do a simulation of the forces onto the already inline stators,
you see, that they have a very different forces around the stator circle !
For instance do a FEMM simulation of the last sequence you posted and
mark one stator magnet after the other and see, what forces pull on them,
although 2 or 3 stator magnets are lifted !
The last one at the right side at around 5 o clock feels
a very big force from the rotor magnet, although there is a gap
right beside it, so I don?t know.... The same force you would
have to apply, when you want to press this stator part back into the circle !
Hmm.... let me know what you thing,...when I remember correctly
it had over 320 Newton in one direction ! That is a lot of force on it !

Tao.
'I already explained exactly how to implement a 0 force situation.
- There is not '0 force situation'. I made the simulation model (see attached) and it clearly shows that 'ALWAYS lifted stator' is under forces from both sides of lifting arms and it always requires power to lower any lifted arms.

'So, you see that the lowering and lifting stator DON'T INTERACT WITH EACH OTHER..
- No, but they do with already lowered ones, and it requires power to do it.

This concept of commutation of field well known and still not solved practically (see attached - one of my models to operate this concept with a solenoid, not a selfrunner).
Hope you can solve it.

@Light
Please tell us , how your

reacte and behaves !

Maybe you can post a short video playing
with it and speaking with it, what you just do and
why it does not work yet ?
Many thanks.

I think the femm sims are all going to be off. the magnetic forces in this device are 3 demensional. (i know already been said) on top of that there are hundreds of things not thought of in all these sims. though this device is mechanically simple it is magnetically complicated. an actual replica and physical simulations are the only present way to show the forces on this motor.

a sample of some un figured problems in torque.

mechanical drag and friction - bearings, pins, shock, vibrations, air (i recomend enclosing device in a vacuum tight case after

completing and including stabalizers to final product)

temerature differances/ problems - friction of bearings and cap on rotor creates heat... heat transfer to rotor magnets, high friction area around stator arm pins create heat, environmental temperatures. (all these depend on heatsinc and precautions taken)

size and distance - the magnets feild reaches a peak stregnth at the center of its feilds (inside the curve) and placing the magnets closer or farther from the rotor is going to effect things as well as the size and quality of the magnets you use.

effects of different materials used in the building of the device - any material that reacts with magnets is going to effect the device

i believe this to be a high yield device, and femm helps to create a higher yeild through different setups, but any sim provided in this case is not going to be acurate without some aditional calculation. these femm sims are theoretical in nature, but are still very usefull in finding better setups. (exp. you say that bar magnets will create more torque/reaction than the curve/half moon magnet torbay used.... ) this is good info.

thanks for your ideas....... this is just my oppinion.... so dont bite my head off.... i know i am wrong on somethings.... just let me know where and how.....

thanks,
danny

p.s. i say this only becuase everyone is so obsessed with the femm sims that i think it is taking away from the rest of the project...
