Elementary 3-phase round rotor synchronous generator

ALTERNATOR

The elementary 3-phase 2-pole round rotor synchronous generator has a stator equipped with 3 coils displaced 120o from each other; although shown as concentrated, they actually are distributed. When the rotor is excited with dc and rotated, the resultant field will also rotate so that sinusoidal voltages are generated in the 3 stator phases.
