I'm really wondering why you are messing with this relic from the early
1960's, at best. I'm pretty sure the field is 2-pole, so that means the
thing has to run at 3600 RPM to make 60 Hz power. It is going to sound
like a shop-vac when running.

There has to be a regulator to keep the dynamotor at 3600 RPM, and they
can't use the field to do that, as that is what regulates the AC output.
I can't figure from the armature photo how the speed regulator functions.
They might have an AC frequency detector that cuts a series resistor in
and out of the armature circuit, or even just switch the armature current
on and off to regulate speed. Almost certainly it varies field strength
to regulate AC voltage. Probably with all the regulation jumpered out it
will run a bit above 60 Hz and 120 VAC output, which might be fine for
running a small power tool at a remote site.

hey jon,
i didn't know it was a relic. (i always figure like, a bow and arrow or a
cannon can still kill someone just as well as a (what's a new high tech
weapon?)) yeah it'll be loud, but i thought it would be neat if i could get
a 1600 watt inverter that produced a sine wave for $185. the sine wave
solid state inverters cost a lot more than that, and i figured it was
mechanical so if there WAS something wrong with it i could fix it, i'd be
leery of buying a solid state device used off eBay. (but i think i did end
up getting screwed on this deal anyhow though, but wouldn't have known that
going into it.) huh, thanks for the info about regulating it's speed. i
assume that must be what the MISSING circuit board must've done. :-( the
guy's auction said "as is" but also said "works good", which sucks. yeah,
small power tool at a remote site. that was kinda what i was hoping to get
out of it, and maybe also, i hoped, running the blower/burner on the boiler
in my basement during a power outage in the winter. hoping that maybe i
could charge up a "bank" (two deep cycle car batteries) and shut off the
(noisy) generator and run the boiler (etc.) off the inverter for a while.
it seemed from what i read this inverter was versatile, can run electric
motors but also computers, etc.. noisier than a solid state inverter, but
the trade off was that it didn't cost thousands of dollars. well, not yet
at least.

b.w.
