thats not much help at all.
try reading:
Analysis of electrical machinery, Krause et al
matrix and space-phasor theory of electrical machine, G.J. Retter (this is a GREAT book).
OR google Parke and Clarke tranformations
OR figure it out with high-school trigonometry. the idea is this: with 3 rotating phases, separated by a fixed angle, the system is over-determined (more equations than variables). This is even more so when all three vectors are balanced. you can thus represent a balanced 3-phase set of vectors with a SINGLE vector, rotating at the same angular frequency
