This wind turbine has a 40 cm (15.75 inch) diameter and is driving a Howard Ind. 1-19-4203 stepper motor. The two coils are wired in series. At about 5m/s (11.2 mph) it loads a 8.8V battery by a current of 4.0mA. Its rotor is made of plastic pipe.

  • 4.5 ma would only be about 39mw. That would light 6-10 LEDs. Are you sure it wasn't 4.5 amps?  That would be 39 watts, which seems more reasonable and pretty good for a turbine of that size.

  • 4.5ma * 8.8v is only 40mw of power, that would light about 6 LEDs. Are you sure it wasn't 4.5 Amps? That would be 39 watts which is more reasonable (and pretty good) for a turbine of that size.

  • ok.
