Warrior, the fan that I was using had 32" blades and it was rated at around 100watts. The kind you find in warehouses. The blades have a bend 8" from the tip. This last month the turbine ran almost everyday.
I will add a fourth wire to the second windings, this will separate the phases. I also have two sets of blades for the unit. The one's in the picture are slower but they start in very low winds.
