Metal Windmill Blade

First, the major components of a windmill. It won’t take much time to familiarise yourself with these key components and some of them may be already known to you.

Anemometer. Is basically a speedometer for the windmill. It is a gauge to read how fast the blades are rotating. The most sophisticated systems have a feedback route to a control computer regulating the blades’ speed so that damage won’t occur at high speed winds.

Blades. Most turbines have a minimum of two blades, very similar to that of airplane propeller. Standard windmills have more than two blades. When wind impacts the blades, it causes a ‘lift’ which will make the windmill rotate.

Brake. Most commercial or industrial windmills have a brake. The brake is used to stop the windmill in an emergency.

Controller. Again. Most commercial and industrial wind turbines are computer program controlled. One function of the control program is to start and stop the wind turbine. Wind speeds of less than 3mph per hour usually don’t generate any electricity, and winds greater that 50mph can cause damage to the windmill. The computer program will regulate the windmill operating between these wind speed ranges.

Gear Box. Larger windmills or wind turbine systems have gearboxes, usually to increase the shaft speed from 55 rpm to a maximum of approx. 1800 rpm (revolutions per minute). There are also ‘gearless’ wind turbines which have a lower failure rate and which are known as ‘direct drive’ systems.

Generator. This is the part that actually generates the electricity. Similar to an alternator (or generator) in your car, the generator makes the electricity.

Nacelle. This is the definition for the cover or caging that protects the generator and gearbox if any.

Pitch. Pitch is the ‘tilt’ of the windmill blades also explained as the angle that the blades are at to “capture” the wind so the generator will rotate. Too much pitch can make the generator turn too fast and damage the windmill and too little pitch will disable the generator to rotate.

Rotor. The rotor is attached to the generator shaft and holds the blades and hub.

Tower. The tower can be made of wood or strong PVC pipes on smaller windmills and is usually made of steel or aluminium on larger units. This is what holds the windmill up into the airflow.

Wind Vane. This is the tail that helps keep the windmill pointed into the wind.

The Vane is very important for maximum power generation.

While this list shows only the basic parts and is far from everything you’ll find on an electricity-producing windmill, at least you will now have an idea you’re your windmill repair service or parts supplier is talking about.

  1. Just wanted to say HI. I found your blog a few days ago on Technorati and have been reading it over the past few days.

  2. Wind power calculator
    Here’s a link to a calculator that shows you how many kilowatt hours of electricity per month any size wind turbine will generate based on wind speed and the length of the propeller.

  3. more than two years ago, I wrote this article to propose my idea of the Wind Energy Skyscrapers:

    http://www.gaetanomarano.it/articles/028energy.html

    then in the days/months/years later, I proposed my idea on dozens websites, forums and blogs

    now, a New York Times article, reports an interesting study of the Harvard University

    http://greeninc.blogs.nytimes.com/2009/07/16/study-suggests-wind-power-potential-is-much-higher-than-current-estimates/

    http://www.pnas.org/content/106/27/10933.full.pdf%22

    the study shows that, the power of the wind, is SIX TIMES greater than known before!

    this because, the new calculations, are based on the energy produced by wind turbines 100 meters tall or more

    so my idea of Wind Energy Skyscrapers was and is extremely valuable and innovative!

    therefore, I decided to propose again my idea, to several websites, forums and blogs, in case they want to talk about it

  4. How much a 1 megawatt windmill will cost?

  5. We are looking for replacement props for a Nordtank 653, and a nacelle cover with the linkage bars to hold the cover up when open for service, also possibly any other source for miss. parts such as high and low speed couplers, brake parts etc. contact us by email or phone at (605)867-1544 / (605)441-9200 / (605)407-7127 or (605)407-9174. If you reach Henry give him the message and have him relay it to Bret

  6. needing props and miss. parts, Nordtank 653, late version design
