Wind energy

[mosfet123]

Hi;

İ will make simple lighting fixture that working solar + wind turbine. I want to work about 30 or 50W le module . Actually i dont known about wind turbines . Does anyone have information or documentation on how to do it?

To experiment, drive a DC motor via propeller mounted on the shaft. You'll measure voltage at the terminals. Voltage increases as speed goes up.

As soon as you attach a load it makes it harder to turn the motor. A small motor (cassette motor, shaver motor) can power a flashlight bulb. However to extract greater power you need more wind speed, or bigger propeller, or gearing, pulleys, etc.

A useful type of motor is a windshield washer motor. Say 12 volts at 1 Ampere.
To obtain 30W it's better to have a generator. A motor is designed to be a load and to appear as a load to the power supply, rather than be a power supply itself driving a load.
