MylowHJ Replication - Discussion

[carbonc_cc]

Based on my own testing, I noticed that as you add more magnet groups, the stator works less and less.

I have attached a drawing which I believe should overcome the "closing the loop" problem.  Going 3D instead of just 2D should remove the distorting effect of adding magnets on a single platter.

One might even try a double heliux pattern like that of DNA...  Sprial down

Copy that ..
every mag array or smot i ever played with did same.

i finished building the 16.3 disk array today after the promising look it showed yesterday.
i posted two vids of the tests i did today . . but the news is not encourageing..

This array 16 = (4*4)  * 3  acts like every other so far . . as you continue the build around the disk ..
i tried it in symmetry and not  4.4.4.4 + 4.4.4.4 + 4.4.4.3
there is less and less movement up until you close the loop .. once you do
there is not enough momentum to  break through the wall of repulsion sitting at the beginning of the next segment.

Every array i ever built to date has done this . .so far this one is no different.

Later this weekend i may build 16(4*4) in some other config.
If i understood one of Sterling's earlier posts he is sending Mylow some rotors that are same as mine

.. if this is the case and Mylow can get them to work then he can share the config with me so i can replicate it.

Early next week I will also have one of the same stators as Mylow if my shipping ETA holds up.

Yesterday i asked Mylow ( projectMagma )  to  look and comment on my videos .. big silence ..

Until there is a replication .. nothing here ..
move along

"Based on my own testing, I noticed that as you add more magnet groups, the stator works less and less."

This is because each magnet group you add just builds a larger and wider composite B field.  The
stator will try and seek the point of maximum attraction or minimum repulsion, or the summation of both
using both poles of the rotor magnets in our case but will usually be in the middle of the array.  As you close the loop, the array goes dead as there is no point of maximum attraction or minimum repulsion.  There is still plenty of B field but you just poured molasses over the whole mess.  Isn't symmetry wonderful?

Last night I stubled upon flux measurments that can be done quite easy by a using hall sensor.

Would it be an idea to put two hall sensors on the stator magnet, one at each end.
Voltage of these sensors could be measured by a sound card input (two channels) of a PC.
In this way one could easily get more insight in the field alteration of such setup.

p.s. I will do a bit more research later on to show how this can be done easiest.
