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
