How can you specifically control the number of frequencies per second (Hertz) of alternating current?

The frequency of the German power grid is 50 Hertz, while in America it is 60 Hertz. Personally, I only know that the number of frequencies can be controlled by the number of rotations of the rotor in the generator, so if the rotor in the generator rotates 50 times per second around its own…
