You might mention that the huge rotor in the hydroelectric generation plant shown in the right frame of the final photographs has a very large number of poles because it rotates much slower than 3,600 RPM or 1,800 RPM. Large hydroelectric generators have significant amounts of synchronous grid inertia.
