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?

This is the sister engine, one serial # apart. We set this one up
about 10 years ago.

Thanks Scott. I haven't seen any like that, looks like the slide valve
is built into the bearing housing. What's all that stuff in the middle
of the flywheel do?

That is not the slide valve, it is a Skinner (ego Poppet Valve) engine.
The stuff in the middle of the flywheel are weights and links for the
governor. The ring right near the chain moves on the shaft to control
the admission valve cam.


Sure looks heavy!

As a freind used to say - those things are made out of heavy.

Amen!


The flywheel is the giant ring with square holes (it is painted). teh
square holes are for the guys like me to lock a jack in so the engine
can be turned slowly and controlably for any of a number of maintenance
procedures.

Per a resounse above - the unpainted thing is a ring of field poles. It
is called a salient pole mancine as opposed to round rotor. You could
could them and devide by 3600 to figure out what speed it ran (sllooww).

Matt, thanks for the explanation. This machinery is a bit
outside my experience and I appreciate the chance to learn a
little about it. Is there a particular type of plant that
uses these generators?

Doug King

Thanks, the owner is good looking too.

This is the smallest steam engine I've handled. The bigger ones
are around 50 ton. Those 3 pieces were 20 ton. The whole engine
weighs 35 ton. I hauled a complete engine once because I didn't
want to go back to Long Island a second time.

Scotty

Nope. that's the flywheel. See all those square indents around
the outside, middle? that's to hand crank the engine. Put a big
bar in those holes.

Right. It's the rotor. The stator isn't there. It's being
rewound at the moment.

No belts or anything touches the outside of the flywheel. The
exciter motor belts run off the shaft. I don't know why it isn't
painted.

It makes sense when you already have the steam available, and the
cost of electric is high. The one in place powers part of a
mental health care facility. With both engines up and running,
they will power the whole place.
they already had 2 big coal fired boilers and I brought them an
oil fired boiler last year.
Most of the engines are from the 30s - 40s. The oldest I've
transferred was a 1912. Lots of exposed , whirling parts.
Most of the engines are running wood mills where they burn the
free sawdust in the boiler.

SBV

Oops, I think maybe it's a Uni-flow. Big difference, huh?

I don't think is is a multi flow because all that I even ran
