i'm looking at 16 magnets . 1"x1.5"x.5 "
i could lay them out on a 10" rotor and build a single rotor axial alt
and for comparison purposes, using a stationary return path.
i was thinking two phase, with 32 overlapping coils.
as an alternative,
it would be possible to do a single rotor radial alt.
placing the mags on the inside of a 4"pipe
i have in mind a four pole layout with the poles consisting of 4 magnets each.
sticking with the two phase idea, i would require only 8 overlapping coils.
right away i can see an advantage in reduced resistance. as i am eliminating the ends(non productive copper) from 12 coils while retaining the productive copper.
there would be the same amount of magnetic flux crossing the coils.
but the frequency per rpm would be reduced from 16 to 4.
over all i think there might be an increase in current but a reduction in voltage.
any thoughts?
