The stator contains six coils of copper wire, cast in fibreglass resin. Wires from the coils take electricity to the rectifier, which changes the AC to DC for charging the battery.

Small wind turbines (SWTs) are, however, still visible around the world for a variety of appli-cations, including electric power generation for households, industrial centers, farms, and isolated communities; com-bining with other energy sources and storage in hybrid en-ergy.

A vertical-axis wind turbine (VAWT) is a type of where the main rotor shaft is set transverse to the wind while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair. VAWTs do not need to be pointed into the wind, which removes the need for wind-sensing and orientation mechanisms. Major drawb.
