Is anyone interested in the results if i run this test?
The way to make this comparison completely fair, is to use 40 magnets, 1.875x.875x3/8 thick, ferrite of course, because i already have 50 of them.
5 magnets per pole for the 8 pole machine and 4 magnets per pole for the 10 pole machine. i was going to have the 40 magnets touching at the inner diameter, so we're looking at 11.4" inner diameter and 15" outside diameter.
The coils remain exactly the same, except that the polarity is changed and the phase order is different.
The 10 pole machine has a .966 winding factor and the 8 pole has a .866 factor. As I understand it, most everyone on this forum is using the 4 magnet 3 coil ratio which is a .866 winding factor, which ..i know... doesn't entirely transfer over to non air core machines.
but basically i should expect to see more voltage and power out of the 10 magnet vs 8 magnet machine, from the exact same amount of magnets.
If this is true then it would make sense to do further testing.
I have about 70 pounds of 26 gauge wire, and friends who like 3 d printing so it would be rather easy to change the id to od ratio of the coils, as well as change the thickness, but this can be done rather easily with single layer test coils.
I have a lathe that can swing 14 inches without taking the bed gap out, so i might just shave off the inner edges of the magnets so i can fit them on a 14" disk.
I know a lot of you seem to have neodymium magnets that are spaced rather far apart.
It will be interesting to compare the output from both the 8 and 10 pole count magnet plates.. but with 1 magnet removed from each pole.. which almost works perfectly: it would be 30 magnets for the 10 pole count machine, and 32 magnets for the 8 pole machine. i would say 30 vs 32 is within the limits of normal harry home shop accuracy.
edit: just realized i will need 80 magnets, not 40. for the two magnet disk, single stator, standard design. (32$ on amazon for 50 of those things, so its negligible compared to my time).
