A windmill that generates electricity is called a wind turbine. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed through the speed reducer to promote the generator to generate electricity. Wind power generation converts wind energy into mechanical work, drives the rotor to rotate, and finally outputs alternating current. Wind turbines can be divided into two categories, one is a horizontal axis wind turbine, and the rotation axis of the wind wheel is parallel to the wind direction.

One is a vertical axis wind turbine, and the rotation axis of the wind wheel is vertical to the ground or airflow direction.
