work as a generator, how to hook it up, and what size capacitors I would
need to get it to self excite. The closest image of it I coluld find was

They have much lower efficiency than excited units, around 70%, and the
output actually goes down as the load goes up. The primary use of this type
of generator is in applications that must withstand a dead short, ie.,
welders. When shorted, the excitation goes away, and the unit shuts down
reliably and safely. But for any other application, it's a bad choice.

| Thanks! The first link I had already been to but the second seems to be very
helpful.
