2021.3.4 Introduction. A windmill is a structure that converts wind power into rotational energy by means of vanes called sails or blades, specifically to mill grain (gristmills), but the term is also extended to windpumps, wind turbines and other applications. The term wind engine is sometimes used to describe such devices. [1]

The wind energy is converted into rotational energy. The working of the windmill is explained in the figure below. When the high-speed wind blows over the windmill, the blades or sails are turned. The blades move such that the shaft starts to spin, resulting in the production of electricity. Blades control the functioning of rotor speed.
