Interesting, have any more information for us? Did you actually connect it to a load or was it just free spinning, what pressure did you test it at? Did you actually turn on into an engine.
Gerotors are cool. They are another form of positive displacement pump/motor but I haven't seen them in larger applications vary often, I'm not sure what the advantages/disadvantages are over other pumps. I think the reason you usually see them in smaller applications is because the ring gear part spins with the rotor which adds a lot of spinning weight, otherwise the
rotor must orbit around the ring gear thing (think its called a scroll?). Actually a rotary engine is basically a 3 lobe gerotor with a fixed "scroll" and a orbiting rotor. Anyways I think a gerotor pump/motor could work if you can find a complete unit that's large enough for this application.
