Why does the speed of wind have no affect on a homemade electromagnetic generator attatched to a windmill? I did an expiriment using a windmill and altered the wind speed 3-11mph. There was no change in the amount of amps genrerated. Are my results just wrong or is there a reason for this weird occurence? Thank you for your time.

  1. The generated output voltage should increase with the rate that the windmill turns. The current will also rise if the output terminals are hooked up to a fixed-resitance load. If that is not happening, I don't know why.

    Some windmills (and solar panel arrays) are locked into a fixed rotation rate by a power grid and controlling circuitry. The windmills turn at a fixed rotation rate to match the 60 Hz grid. As generated power changes, the phase angle of the output AC changes but the voltage does not.
