I don't think that is a flywheel with all that stuff in the middle. It is
the end of the housing frame for the generator/alternator.

The notched wheel at the outboard end looks like it might be a row of
magnets for some type of generator, but it doesn't make sense to power a
generator with a single-cylinder steam piston... unless these things are
pre-1915 which they don't look.

The notched thing on the end is an armature. Each of the protrusions from
the notch is a pole.


But it's still going to function as a flywheel with all that rotating
mass, no matter what else is going on. And a single cylinder engine needs
a little something too.

The armature does act as a flywheel and as a braking mechanism, depending on
the electrical load..


.... If it was a flywheel, why is the outer circumference unpainted?

Because it's cheaper that way? Because it was also used as a PTO by belt
or friction wheel at some point? Because it used to be painted but wore
off?

I was talking about the big round thing to the right of the armature. It
looks like it goes into the frame of the generator. It also supports the
bearing for the shaft.

Some things man was not meant to know... and some things you just can't
tell from pictures.

Looking at the pictures again, the big thing to the right of the armature is
the stator. The armature has slid out of the stator.


... It looks like some type of variable reluctance mechanism.


Dunno. Could be. Looks like an interesting piece of machinery anyway. And
you're right, Scott does have a nice truck!

That truck costs more than RB's boat!

I wonder if Scotty likes his truck more than his boat?
