Are generators built like an alternator of a generator

(OP)
Are power generators such used for home emergency power and the generation of power by a nuclear power plant built such as an alternator or like a generator where the armature revolves??

Most all modern machines use this format.

RE: Are generators built like an alternator of a generator
Historically, a small rotating field machine would have a small DC generator on the end of the shaft to produce exciting current. You had one set of brushes on the commutator taking the DC current off and another set of brushes supplying the DC to the rotating field. Compared to that, some manufacturers opted for a stationary field and used slip rings to extract the output energy from the rotating main windings.
With the perfection of silicon diodes brushless exciters became more common. There are many larger machines (20 KW and up) with rotating magnetic fields that have been converted from brush excitation to brushless excitation and are still in service.
The stationary field machines have not, to my knowledge, been built for many years, and very few remain in service.
