The horizontal-axis or vertical windmill (so called due to the plane of the movement of its sails) is a development of the 12th century, first used in northwestern Europe, in the triangle of northern France, eastern England and Flanders. It is unclear whether the vertical windmill was influenced by the introduction of the horizontal windmill to Southern Europe in the preceding century.

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. Used less often than their horizontal counterparts, VAWTs are more practical in residential areas.

VAWTs are typically small wind turbines that are characterized by an axis of rotation that is perpendicular to the ground (see Table 20.6 for a selection of VAWTs). As a result, VAWTs can operate independently of wind direction, which is a major advantage for urban applications where wind direction can change rapidly.

Traditional Vertical Axis Wind Turbines (VAWT) Vertical axis wind turbines, as shortened to VAWTs, have the main rotor shaft arranged vertically. The main advantage of this arrangement is that the wind turbine does not need to be pointed into the wind. This is an advantage on sites where the wind direction is highly variable or has turbulent winds.

Angular speed is the measurement of degrees traveled per unit of time. For example the minute hand on a clock rotates at 360 degrees / hour. It can also be measured in radians / hour. Every point on the wind turbine blade has the same angular speed because each point rotates 360 degrees in the same unit of time.

So vertical axis wind turbine needs an automatic brake system. As a wind turbine starts to brake, it must overcome the rotational inertia and the driving force from the wind. So a good design calculates the torque in the rotor at survival wind speed and chooses a suitable disk brake for that amount of energy.
