Savonius Wind Turbine - The Solution To Can We Make Wind Power Electrical Generators Workable


There are a number of wind turbine design types on the market and this article details the specifics of the completely unique Savonius wind turbine. Unlike the more common horizontal home wind turbine designs, the Savonius home wind turbine is based on a perpendicular architecture that relies on scoops to revolve in the wind. This rotation is then transferred through a vertical shaft to the generator for the production of electricity. This home wind turbine is the perfect choice for applications that take minimal power, but ultra dependability The simplicity of the Savonius design makes it a popular choice among applications that require as little maintenance as possible.

In the area of wind generated power there are an assortment of styles of equipment used to capture the power of the wind and transform it to electricity. Most of the designs follow the typical style of a windmill, or airplane style propeller that sits atop a tower and rotates to catch the wind. The Savonius wind turbine style is different in design because it is a vertical axis wind turbine (VAWT). This means that the actual piece of the turbine that rotates looks more like a spinning canister that attach to a vertical shaft joined to the generator also mounted vertically near the ground. The vertical shaft then catches the wind, spins the shaft to the generator to generate the electricity.

The earliest design of this form of turbine was done in 1922 by Sigurd Savonius, a Finnish engineer. This kind of turbine is used quite often because of it's straightforward design and dependability. Additionally, because it spins on a horizontal axis, there is no need to have a directional contraption to keep the unit aligned with the wind like other models. It can catch the wind in any direction and reacts right now to changes in wind direction. This type of turbine is considered a "drag style" turbine from an aerodynamic point of view.

It is designed on the principle that because of the canisters form, it experiences more drag when moving with the wind than against it and it takes advantage from the differential created and converts it to rotation. Considering in general drag type turbines are less efficient, they does not deliver as much power as its more usual horizontal cousin, but can still have a full range of applications. This sort of wind turbine is used in nearly all of the atmospheric monitoring stations around the world since these tend to be located in remote areas and the value of reliability and low power consumption make the Savonius wind turbine a perfect choice.

They are also used on other inaccessible locations like buoys far out in the ocean. They are also sometimes used to entice attention to advertising signs. In this use they are not used to create any power, but have opposite sides painted contrasting colors to grab your attention as they spin. So in general the Savonius wind turbine is a very unusual design that lends itself to many varied applications. Its simplicity and reliability make it the perfect choice for situations that require low power generation, steady performance
