How would I choose the most efficient electric motor to use as a generator for a small wind turbine?
I have a school project to build a small wind turbine (approx. 8" propeller diameter) to produce the maximum out DC voltage possible. We are still deciding between a horizontal & vertical orientation (leaning towards vertical) but we need some help on understanding what we should look for in the motor/gear setup in order to produce the maximum possible voltage at relatively low wind speeds. What should I look for and where would be a good place to buy/scavenge these parts?
