How do windmills work?

Answer 1

The blades are twisted so they rotate when the wind blows. This rotation can be used to turn millstones to grind corn into flour, or to pump water out of the ground, or to turn a turbine to produce electricity.

The sails of a mill are set at an angle to the wind. As the wind spills off the sails it imparts some of its kinetic energy to the shaft and starts it turning. A tail fan is used to automatically point the mill into the wind. The rotating shaft has a gear wheel which supplies energy to the hursting frame, where the two millstones, one fixed and one rotating, are kept a small distance apart. Grain is fed into a hole in the center of the rotating stone and progressively moves to the edge whereupon flour falls into sacks via a chute.

Wind produces kinetic energy which moves the rotor and, when the rotor moves the gears also move and turn the generator. When the generator turns, it will change the kinetic energy turn to electrical energy.

A:A windmill works on the principle of wind energy. when the wind blows its force make the blades of the windmill to move. they move in circular motion . thus, the energy of wind can be made to electricity or to grind grains into flour. it is a much better way as it is Eco friendly.
Windmills have large blades or propellors which catch the wind. When the wind blows the blades turn. This turning motion can be used to grind corn, pump water or generate electricity.
Wind blows into the large fan, fan has a shaft through the centre that extends to the rear. Flange fitted to the rear of the shaft has a connection point like a stud or such. A long shaft is then attached to the connection (must be a flexible connection & shaft usually runs down vertically to well/bore), As the flange spins with the fan shaft, the attachment point prescribes a vertical circular motion, the shaft attached to the connection point will be raised up and down as the fan completes each circle. The shaft can then be attached to any other mechanical device that can use such energy.
