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. If it was a
flywheel, why is the outer circumference unpainted? It looks like some type
of variable reluctance mechanism.

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).

These are the 3 big pieces to it. The smaller stuff will come
later.

The crank / flywheel / rotor assy. Weighs 9 ton.

This is the sister engine, one serial # apart. We set this one up
about 10 years ago.
It's very dark in the powerhouse, so most pics came out too dark.

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?

Sure looks heavy!

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?

You've done that too, eh? I was amazed at how easy they turn the
first time I tried it.
