I have a 35KW gasoline egine powered generator that came off of a Naval Ship. It was built by Hobart and I can only guess its age to be somewhere in the 1930's or 1940's because of the fact that engine is a 6 cyl flathead and it just looks like it came form that era. The funny thing is that the engine has no identifying marks on it anywhere as to who made it. Is anyone familiar with any of these gensets? The generator is a 120V Delta 3 Phase, but I am not sure of the frequency whether it is 60Hz or 400Hz. I am told that you can count the number poles (just the same as in any AC motor) in the generator to determine the frequency. The generator runs at 1200rpm. What am I physically looking for inisde the generator so that I can count the number of poles? Does anyone know where there is a picture that shows me what the poles look like?
