i have an additional question.
there seems to be a convention when relating formulas on a computor .
you guys use this ^ symbol, what does this mean?

I must say that I haven't read all of the formulas yet.

However, in general the ^ symbol means to the power of....

^ 3 would be Four Cubed = 64
^ (1/2) would be four to the half power which is the square root of four = 2

I would assume that is the same convention that is being used here. Does it make any sense?

Hi electrondady1.

What is these size of your ceramic magnets. I made a dual rotor alt with 24 of the Lowes $1 ceramic blocks.

It is the standard 24 mags (12 per rotor) and 9 coil 3 phase. Saw over 225 watts at 30 mph and cut in befor 10 mph. 10" rotors.

You might concider that and if you have enough magnets make 2 gennys?

hello jerry, thanks for responding , as a matter of fact it was your experiment with the 120 volt delco alternator that got me thinking along these lines .
like your self i found i had collected quite a few hefty ceramic mags from loudspeakers(i play bass guitar)over the years.
i just cut them into segments with a wet tile saw. these mags have been used in about a half a dozen different configurations exploreing different shapes , spacing, etc.
the last experiment was a three phase tripple rotor, dual stator, it used 12 coils(on each stator) over 16 poles(four mags each ) on 10" disks . i beleave i got 8 volts dc from this configuration using a total of 24 coils of 19 gauge using 32 turns.
a vawt is the most practical for my situation so i want the genni to cutin at around 60 rpm.
so using about the same magnetic mass ive dubbled the no. of poles and opened up the dia. to 14" for more linear velosity.
these poles are formed from three seperate mags. 1/2" thick. they form a wedge shaped pole that is 2 5/8" long 7/8" wide at it's widest and taper down to only 1/4".
it would probably be possible to use the twenty four coils from the tripple rotor unit on this one . and go 3 phase. the poles are about the same size.

it would also be possible to place all the ceramic mags in green garbage bag and toss them into the river! but, i grew up so poor i have a very hard time throwing anything away.
