    Hi guys Im creating another wind turbine generator do you have sample projects that you made yourselves? because Im having a hard time finding a schematic diagram for a wind turbine generator.

    I just Googled "home built wind generator" and came up with enough reading to last a lifetime.

    You will probably need a motor that operates from greater than 12V. Also, since wind turbines are generally low RPM, you will either need a gearbox or to rewind the motor to generate higher power at low RPM.

    Or you could use a boost converter if you get less than 12V from the turbine.

    MPPT can also be used with wind turbines

    What voltage and amperage are you aiming to ? For what purpose ? Charging an automotive battery ?

    Find a discarded thread mill and use its permanent magnet DC motor as generator. Run it at the highest rpm you can.
