Magnet Motor from Argentina, part2

[hartiberlin]

I was too tired this night to comment the
simulation from:
http://www.overunity.com/index.php/topic,933.msg6699.html#msg6699

There I tried to see, how big the forces are that are occuring,
when the stator magnet at 5 o?clock is moving towards the
stator line and when the stator magnet at 9 o?clock is moving away and
is widening the gap there.
The curious result is, that you get a supporting force of about 31 Newton
to move the 9 o?clock magnet away, which I would not have expected.
But otherwise you have to  the push the 5 o?clock real hard
with the vectorsum from 52 and 117 Newton into the line again.
Now the energy it takes is Force times distance, so I would
have to make several small step movements of these stator
magnets to see, how the forces are changing via the distance.
This would be a perfect application for the LUA scripting,
but I have not yet learned this and in this moment I also
have no time to learn it..
So maybe somebody with LUA knowledge can do this.

Here is another simulation picture.
If you put the stator magnet back to the line
again after the rotor magnet has passed, it needs
less force to pull back the stator magnet into the stator line.

Hi Tao,
thanks for your last simulation pics.
Why is the torque so much bigger, when the
rotor magnet goes a bit into the gap  ?
It jumps from around 2 Newtonmeters to around 20 Newtonmeters,
but why ?

Hi Tao and ALL,
I guess we can get a lot more torque, if we
use several moving gaps !
Like the difference between a 2 pole or 4 pole
motor, we will have more torque, if we have 2 moving gaps
instead of one moving gap.
Maybe we can use 2 gaps at 180 degrees apart or 4 gaps at 90
degrees apart.
Then of course we would also need more stator magnets, but as the rotor
seems to produce more torque, when it comes into the gap, more gaps
can have a positive effect onto the torque.
I will try it in a simulation now.

Regards, Stefan.

Hi Tao,
maybe you get such a strong 20 Nm torque, cause you used
these many Neodym vectors on the rotor part ?
Maybe they add up in the field strength ?

Tao,
maybe use a few less neodym vectors and see, if the
torque will also go down at the same position.
Thanks.
