What servo motor to use??? | 11 comments (11 topical, editorial)

Well I bought 2 of those motors. The heavy cast iron flywheel ended up being a blessing in disguise.. NO matter where I went (hardware stores, bolt supply stores you name it) I could not find a nut to screw onto the shaft. In desperation I took my hacksaw to one of the flywheels and cut off the pulley that had the threading in it. I machined the sides into a hexagon. I have one of the motors hooked up to a drill press, slowest speed about 500 rpm, and it puts out about 160 watts.

Since the threading is left handed, I am making my turbine blades run counter clock wise.. Or if you plan on running purchased blades, you could probably run a downwind setup.

One worry is that the motors have brushes that will eventually wear out. Since this is my first generator and I still want to experiment, I see this motor as a temporary solution.
