Oddly enough I didn't receive my original question either, though clearly some people did.

It was a bit of a long winded post on reflection so I'll shorten it:

Single phase alternator with no direct electrical connection to rotor.  Rotor has a coil, the ends of which are joined by a rectifier.  Stator has two coils, one for the output, one to provide field.  In this application (240v 50Hz 850W gas powered generator) the field was connected to the output coil via a simple current limiting capacitor.

It simply not a configuration I have seen before, and I was curious if it had a name.
