Wind Power Generation: Calculating Output from 30mm Turbine

[stu1984]

I am looking to design a few ‘wind powered’ gadgets, on a very small scale. I am struggling to calculate the power generated from a turbine of about 30mm diameter. I understand that the number of coils surround the armature has an obvious effect on the generation, but was wondering if there was an equation to unable me to calculate the output under certain wind speeds?

cheers

There should be documentatin available to show output at various rpm's for your alternator of choice. Most have built-in regulators to limit that output if the unit is overdriven. The other factor will be your gearing between the vanes and the alternator. In some cases (probably not yours), the vane pitch can be varied as well to maintain a certain speed.
