Have you ever wanted to know how a windmill works, the basic parts, and how the function? Are self-built windmill designs or kits practical, and how about using a wind turbine for electricity?

Windmills are one of the ways that people generate power, pump water, reclaim land and harness the ever-flowing power of the wind to their advantage to accomplish any number of tasks. How a windmill works is important to how it generates the power needed to accomplish the task it was designed for.

In basic terms, the benefit of a windmill is the fact that a free source of energy is used. The wind blows, it turns the blades of the windmill, which causes the mechanics inside to move. Depending on the specific purpose of the windmill, a windy day could provide a significant amount of energy.

The parts of a windmill

There are a number of parts within a windmill which work together in order to make a windmill work. You can even build windmill parts for home use from a variety of sources.

A windmill consists of some basic parts whether it is a traditional windmill or a wind turbine. The applications, however, of the various parts may be different. A windmill consists of motor, blades, shafts, and gears all of which work together to provide power, pump water, work a saw or grind grain. The more wind in an area the greater the amount of power which can be generated. There are a number of places from which a windmill system or wind turbine system may be purchased. It is also possible to build your own, however, this is probably the least cost effective unless you are already in possession of an alternator, generator or motor.

Inside of a windmill are a number of parts, the first is a wheel which as it turns moves a set of gears, this in turn is attached to a stroke mechanism which causes a motor to operate.

On a windmill used for pumping water you would find a rod down to the top of the well, a pipe, and an additional rod which would drop down into the well. The movement of the gears, the stroke mechanism and motor would cause water to be drawn from the well by the windmill.

This is slightly different from how a wind turbine works. A wind turbine extracts energy by slowing moving air down and transferring the energy into a crankshaft, which is attached to an alternator or generator to produce electricity. Available power to the wind turbine is determined by wind speed and the blade coverage area.

Build a windmill

It is possible to build a windmill from scratch. It is important to consider safety factors when considering this type of project. In higher winds and storms the blades of windmill can actually prove to be a danger as they may separate from the windmil. Be sure to thoroughly secure the blades and make sure all safety precautions are taken. While it is possible to build a windmill it is not necessarily practical, because windmills can be expensive. It is not the blades or even the tower that are the most expensive, the cost comes from the batteries, alternator or generator, and motor. However, it is possible to recycle parts in order to cut the expense of these parts, which can make building a windmill from scratch more feasible. A little research can also lead you to places which can provide you with the parts for a windmill ready made and simply requiring assembly.
