DougI have a free standing 2 pole generator that I put a hydraulic motor on for a test years ago on my schooner. I took it out because it was just silly running an 85hp John Deere diesel just to make AC which I now don't use aboard since the ill fated micro wave oven joke ran its course. I completed the voyage using the indispensable microwave oven as a food storage cupboard, tearing out the whole mess when I got back to Canada.
Of course, being a classic hoarder, I never threw it away, just chucked it in the basement. The movers moved everything, even that generator, still complete with hydraulic motor.It worked great except for the noise in a quiet anchorage in paradise.Antisocial!Cheers Warren

Hi Warren
Actually the bomb Hector dropped (long time ago but it didn't go off haha) is the idea of converting one of those very common gas powered gensets to a MOTOR....and inside it are the slip rings, the rotor of 2 poles with nice curved shaped pole pieces holding in the rotor windings too.....
And then the stators (armature) also have the nice laminate cores and the nice inward curved shape for the rotor poles and windings to spin past too....
the genset I have and what many people have "going cheap": (650W with 2 cycle gas motor running it at 3600rpm for 60hz AC) will have a 2 pole rotor - in other words windings around two curved pole pieces at 180 degrees...
So simply pulse those coils like a DC pulse motor at appropriate time and polarity to make it spin, i
f you want to "pulse" in alternating-DC (AC) then you can figure out how to do that too pretty easy.
