Thanks a lot again! The thing is The university is going to buy the stuff I need, so why not pick a proper generator? Instead of having to spend hours converting the motor The output must be AC, because we are simulating a hydropower plant Thanks a lot!

Thanks a lot, you're so right about the connection. Yes, I've read I can use a 3 phase motor inverted as generator... Thing is... The university is going to buy it for us, so why not pick a proper generator?

Thanks a lot. Yes, probably pulleys and belts so I can work with smaller rotations on the turbine, right? 1:4 Well, I'll be using a water pump to pull water from a water tank. I can work with the pressure. Btw, the pelton turbine I have is small (check attached pic). Yes, what I said about...

Ok, So I'm bulding a prototype of a hydropower plant, that will be used to teach kids. I have NO CLUE about what generator to use. So here's how it works (check the attached pic): - We have a water tank - A pump pulls the water from the tank - the water is used in a pelton wheel - a generator...

Thanks everyone, I figured out what's wrong. I swaped the 0.6's with the 0.8's Now I'm getting the right results! Thanks again, see ya
