This animation shows the motion of space vectors for the case of an unbalanced three-phase sinusoidal signal:
fA = cos(ωt), fB = 0.4*cos(ωt-α), fC = .7* cos(ωt+α) where α = 2π/3.
The corresponding resultant space vector is obtained from fR = (fA + γ fB + γ2 fC) where γ = ejα.
Positive-, negative-, and zero- sequence components are also plotted.
