Greetings:
I've begun the construction of a small A.C. generator with 8 poles and a 3
phase stator. Instead of igniting wound poles with D.C., I've decided to
use permanent magnets. I don't know the field strengths of these magnets
but, they are Magnetron magnets 2 1/4" in diameter by 3/8" thick, not the
best but cost effective.
My problem is determining the number of turns (20 awg magnet wire) per pole
to achieve the 120vrms output. I can do this by trial but, that would mean
assemble - disassemble until I reach the goal. Each phase will be wound
with a continuous strand, not individual coils.
Does someone have a formula for calculating turns that can speed things up?
Is it 15v or is it 30v North and 30v South per set of poles?
