Which of the following statements is true concerning all rotating-field three-phase alternators?
Official USCG Answer & Rule Citation
Correct Answer: Option C — Each has three separate but identical, interconnected stator windings (one for each phase) acted on by one system of rotating magnets.
Rotating-field three-phase alternators feature a stationary stator housing three spatially separated, interconnected windings displaced by 120 electrical degrees, which are swept by a single unified magnetic field generated by the rotating rotor.
