An advantage of the delta-connected AC generator is that if one phase becomes damaged or open, the remaining two phases can still deliver three-phase power. The capacity of the generator is reduced to 57.7% of what it was with all three phases in operation.
A three-phase AC generator is designed to produce threephase AC power by building - more coils in the stator around the rotor. The three coils are equally spaced 120 apart ° around the inside of the stator. The armature coils are wired so that the generator has three separate output voltages that differ in phase by 1200.
