    Science of Wind Generation. So if the rotational speed of the turbine is increased then torque is decreased and the optimal power is extracted from the wind. The optimal speed is determined by the ratio of the wind speed to the tipspeed of the blades ideally around 5 to 7 for utility scale turbines.

    Windmills are classified into two main types based on the axis about which they rotate. Horizontal axis have the main rotor shaft running horizontally and if the rotor must be oriented in the direction of the wind, a wind vane is coupled with a servomotor. Vertical axis have the main rotor shaft running vertically.

    Wind turbine windmills generate electricity. The wind turbine windmill is characterized by its giant threerotor design. This type of windmill is used to generate mechanical power and electricity, by converting kinetic energy (energy of motion) into mechanical power. The mechanical power connects to a generator, which is converted into electricity.
