A 200amp alternator should be about 30mm thick, the one you have looks around a 40amp unit. Dunno if someone has pulled a swifty on you.
The rotor windings are fairly interchangeable up to a point and don't effect output much, but the size of the stator is where the power comes from.
Rafa you are no doubt correct as I could never get it to perform yet the manufacturer swore black and blue it did what it claimed. Anyway it's probably going in the bin as its no use to me now.
