SINUSOIDALLY DISTRIBUTED WINDINGS

^{The stator of a 3-phase (2-pole) AC machine may be represented by 3 sinusoidally distributed windings [RGB] whose axes are displaced by 120o. When the windings are excited with balanced 3-phase sinusoidal currents, the combined effect is equivalent to having a single sinusoidally distributed  winding excited with a constant current and rotating at the stator frequency.The pulsating space vectors associated with the ABC windings and the resulting rotating space vector R are shown in motion.}
