Horizontal axis windmills have the rotor shaft and electric generator at the top of the tower, and it is pointed in or out of the wind. Smaller turbines are indicated by a simple wind vane, while larger turbines use wind sensors coupled with an auxiliary motor.

The world's tallest vertical-axis wind turbine, in Cap-Chat, Quebec. It is 110 m tall and produces 4 MW of power. A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind while the main components are located at the.

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.

This measurementmay be performed manually by technicians, who have to crawl into the inside of the stator and use calliper gauges that are applied through radial airducts in the stator segments to measure the airgap.
