Hello been a long time visitor of this site and decided I should share my recent successful hydro project.
I'm using a 2Hp 230V motor 2 speed, Using a hot tub wet end (4Hp impeller) in revers and the high speed winding with 200 Uf of ballast capacitor with 200' of 2" polyethylene pipe. At current I'm not sure of the current drop of elevation but I'll try and get that for you all.
At current I have about 15' of head with a high volume of flow, With no load I am getting 102V @ 30Hz Ac, under load I am getting 89V 30-29Hz.
The goal is eventually to get a solid 120V @ 60Hz but for now the system is driving a 25w compact fluorescent with out issue and soon a 12V 15A battery charger.
Addition:
I'm using a method of modifying a standard Induction start capacitor run motor. To do this you bridge the centrifugal switch to lock in the run winding, then you add run capacitors to the phase you intend to pull power from. So in my case I have my capacitor bank on the high speed winding, I have yet to ascertain what my max power draw will be from the generator, Tomorow I hope to have some more info for you along with the pictures.
Pictures to follow soon
