Different machines to meet all needs
Jun 08, 2019 · A wind turbine is a machine which utilizes the kinetic energy of wind to produce rotational mechanical energy in its shaft. The rotational motion of the shaft turns an electrical generator to generate electricity. There are mainly two types of wind turbine available one is the horizontal axis type another is vertical axis type.

When people think of wind turbines, they often visualize the expansive rotors of a horizontal-axis system. A vertical axis wind turbine (VAWT) has blades mounted on the top of the main shaft structure, rather than in the front like an aircraft rotor. The generator is usually placed at the tower base.

A wind turbine, or alternatively referred to as a wind energy converter, is a device that converts the wind's kinetic energy into electrical energy.. Wind turbines are manufactured in a wide range of vertical and horizontal axis. The smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic warning signs.
