All motors work on the same premise. There is an electrical coil.


In electrical fans, power is applied to the electrical coil to induce the load. The load creates a magnetical force that turns the shaft on the fan.


To use a fan for generation, a power supply like wind must be first applied to the fan blades to spin the shaft. On the shaft will be an electrical coil. Magnets must then be applied around the coil so that when it spins, it induces current that can be sent somewhere else.

It's already inducing a current, I can wire it to power a light bulb when it spins. How can I make it charge a battery without the battery just powering the fan? Is it as simple as placing a diode to the battery?

Are you generating AC or DC power?

In a DC application, if the power is generated by a fan, then the positive would go to +, the negative line to the -. I would look up some solar generator set ups to see what they used to make sure a battery gets charged correctly. I know in those set ups, the power from solar goes into an inverter before going to the batteries. So that might be something to look into, buying or creating an inverter to charge your battery.
