Theory #4


Array Theory #4

This is a theory of the potential arrangement of the magnets within the resin array on the pacman. 

This theory is invalid from the point of view of momentum.  There is no momentum.


The diagram below represents the configuration of the system before the small rotor rotates a NOT fully saturated FM across the Array to stop 'inside' the field of Neo #5.

The array is composed of 5 NEO's.  The top 4 are set so that they will be in attractive mode with respect to the FM.   The 5th NEO at the bottom has its poles reversed with respect to the other 4, so it would be in repulsive mode with respect to the FM.  In addition, it is 'staggered' to one side, so when the FM arrives at the hardstop point it will be better positioned to cause the pacman to rotate to the left (of the screen).

Now we see that the FM has started to drop at speed towards the hardstop point.  Because we are traveling at speed, there will be little to no magnetic interaction due to lag, so the amount of force required will be relatively cheap.

The FM has traveled part of the way to the bottom.  During this travel it has been affected by this concept of flux momentum.  As it passes each NEO in turn, flux is induced, but due to lag, this is not immediate and as it passes the influence of each NEO the flux built up accumulates due to flux momentum.

Now the FM has reached the hardstop at the bottom where it has stopped inside the field of the last NEO.  This NEO is in repulsive mode and is staggered slightly to the left.  The FM has accumulated additional flux as it traveled past NEO's 1 through 4 and now at the hardstop point it has more flux than when it entered the array.  The FM pauses here while the flux (potentially) continues to build due to momentum.  The array must leave before the lag of NEO #5 catches up (probably imediately).



Finnaly, the array kicks to the left.



Potentially there are two principles occuring with this theory...

Lag... this allows the FM to pass all the NEO's cheaply and finally get inside the repulsive NEO at the bottom, cheaply.

Momentum... this allows the FM to have more flux then it started with when it reaches the hardstop inside the repulsive NEO.




There were some points made about the construction of the array regarding interference and longevity of coercivity.  A suggestion was made that perhaps the NEO's be spaced further apart and or a shield be placed between each Neo, isolating it from its neighbor.

There would be many timing issues with any arrangement such as this, consequently latches and ratchets etc would be required to orchestrate the movement.
