they are exactly the same thing, structural wise.

the only difference is that, in motors, electrical energy is input to create kinetic energy. and conversely, kinetic energy is input to create electrical energy in a generator.

Umm you still need a current for the electromagnets (or you could use permament magnets). So you need two circuits (whereas in a DC motor you can run both off the one circuit).

An AC motor can't necessairly function as an AC generator depending on if you are using a Universal motor or not (which is basically a DC motor that uses electromagnets) they usually run on AC but would generate DC. Where as the ones with slip rings would generate AC.
