Good question.Without getting into the boring technical stuff. The speed of the engine controls the speed of the rotor. The faster the rotor turns,the faster it breaks stator fields. Which creates voltage.Which also causes the hertz. A four pole rotor will break the fields at 1800 rpm which is 60 hertz. A two pole rotor breaks the fields at 3600 rpm which is 60 hertz. Allot of generators didn't use voltage regulators. The voltage was set by the speed. Which is why it is never a good idea to rev up an engine by hand. Saw a guy do that one time with a Onan CCK. Reved it up and held it open. Until smoke started coming out of his RV. Was a very costly lesson for him
