Wind Generator Components - Rotor: Save Ten With Angie's List!

Most wind generators have 4 basic components.

Rotor: This is the component that includes the blades of the unit, which drives rotor shaft.

Options for the rotor include a variable pitch prop, which gives greater efficiency and aerodynamic blade speed limitation.

Also, look for electromagnetic braking in combination with Aerodynamic braking to reduce the rotational speed of the generator in high wind condition and protecting the equipment from damage.

Horizontal Axis Wind Generator

Wind Generator Components - Horizontal Axis Rotor

The rotor can be either a horizontal axis rotor or a vertical axis rotor.

The horizontal shaft rotors are much more common and is the primary rotor configuration that is used in commercial wind farms.

Most residential units are of the horizontal variety, due to higher efficiencies, less maintenance and proven technology. These units often resemble a two or three-blade aircraft propeller.

The vertical axis rotor is more often connected to the roof structure in some manner or is mounted lower on a mast than its horizontal axis counterpart.

The distinct advantage of the vertical axis rotor is wind direction does not affect unit performance.

Vertical Axis Wind Generator

Wind Generator Components - Generator:

The generator can be located either on-board the unit as part of the actual wind generator system or remotely, say on the ground near the unit.

Grade mounted generators are typically easier to service. Grade mounted or remotely mounted generators are more common with vertical axis generators and the on-board generators are more common on the horizontal axis or propeller-type wind generator components.

Some units that are mounted on a high tower or mast feature a hinged mast, allowing the wind generator to be lowered easily to the ground for service.

Wind Generator Components - Support Tower

Wind Generator Components - Support Tower:

This is usually a tall slender mast to extend the blades into clean air or air with less turbulence or air that is not affected by surface friction.

Look for both solid and hinged mast units, depending on the manufacturer.

Also be aware that you will be required to suppy and install a foundation to adequately support and resist structural loads on these generators.

Wind Generator Components - Inverter:

While this is not usually an integral component on some units, it is a very important part of the wind generator system.

Most wind generators produce electricity that is called DC or direct current. This is the type of electricity that is stored in batteries and drive DC motors. It typically cannot power our homes.

To be useful for home power usage, we need to have access to AC or Alternating Current. If you wish to tie into the grid for Net Metering, you also will have to use the inverter to convert your electricity to AC.

Wind Generators - To Complete The System:

In order to complete the wind generator component system, for use in our homes we need a method of storing the electricity that is produced.

We need this storage capacity because during peak electrical production times there is usually more power generated than can be used by the home.

Therefore, in order to modulate the usage factor a storage component needs to be included in the system.

There 2 at least two methods of storing the power that is generated by the Wind Turbine.

1. Storage batteries: These have been the storage method of choice for decades and are still very popular, especially if the next method is not available to the consumer. The negative aspect of batteries is their relatively high cost and maintenance issues.

2. Net Metering: Net metering is a service that is provided by your electric utility company and is not available in every part of the country.

It works simply by tying the output from the inverter through your electrical panel and directly into the power grid. The power from the homeowner direction spins th electrical meter backwards during peak output or anytime there is more power produced by the generator than is needed by the home.
