Smart drive motors as generators are good stuff, they do tend to take a fair bit of energy to overcome the cogging effect from the permanent magnet rotors. This can be reduced by spacing the rotor out a bit to limit the amount of magnet under the stator pole pieces. I had a small creek with a 10 metre head, 50mm pipe but it was not capable of turning a smartdrive. I used a car alternator, then adjusted the rotor current with a resistor to get maximuim output. That worked well, as I only had a short run from the creek to my batteries. Good luck with the project, I hope it works well Pete |
