Hi I am trying to understand the operation of a basic alternator of 3phase 25 KVA generator. Can someone explain how self excitation works?

I guess what I am unsure about is how the AC configuration works. Is the magnetic field of the stator constant or is it changing direction?? If it changes direction how does the rotation of the rotor fit in in order to provide the required AC output to the load??
