WebThe wind turbine converts wind kinetic energy into mechanical energy and the latter into electrical energy by means of an electrical generator [68]. A typical wind turbine design is made up of rotor blades, a drive shaft, a gear box, a speed shaft, a generator, and support cables and casing [65,71]. Wind turbines can be horizontal-axis or ... WebA gear box connects the low-speed shaft to the high-speed shaft and increases the rotational speeds from about 30-60 rpm to about 1,000-1,800 rpm. Why do wind turbines turn slowly? If there is too little wind and the blades are moving too slowly, the wind turbine no longer produces electricity.
