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.

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.

The lack of change in the amount of amps generated by your homemade electromagnetic generator attached to a windmill at different wind speeds can be explained by understanding the concept of wind power and the functioning of wind turbines.

When wind blows, it possesses kinetic energy, which is the energy associated with an object in motion. Wind turbines use the kinetic energy of the wind to rotate their blades, which are connected to a generator that converts this mechanical motion into electrical energy.

It's important to note that wind speed has a direct impact on the kinetic energy of the wind. The greater the wind speed, the more kinetic energy the wind possesses. So, intuitively, one might expect that increasing the wind speed would result in a higher generation of amps from your windmill.

However, the relationship between wind speed and the power output of a wind turbine is not linear. This means that the power generated by a wind turbine does increase with wind speed, but only up to a certain point. Beyond that point, the power output tends to plateau, regardless of how fast the wind is blowing.

The reason for this leveling off is due to the design and efficiency limitations of the wind turbine itself. Wind turbines are carefully optimized to capture as much energy as possible from the wind, but they also have a maximum power output that they can achieve. Once the wind speed exceeds a certain threshold, the turbine reaches its maximum output capacity, and any further increase in wind speed does not result in a significant increase in power.

In the case of your homemade electromagnetic generator, it's possible that the turbine's design or the generator's limitations have led to this leveling off effect at wind speeds within the range of 3-11 mph. It's also worth mentioning that the size, number, and shape of the turbine blades, as well as the efficiency of the generator, can all impact the overall power output.

To further investigate and verify your results, you could try conducting the experiment with a wider range of wind speeds, or consult resources and guidelines on wind turbine design to ensure that your setup is optimized for power generation.

Remember, renewable energy systems like wind turbines are complex and involve multiple factors, so it's essential to experiment, analyze, and iterate on your design to improve its performance.
