# How big is a wind turbine motor?

## How big is a wind turbine motor?

Generally, a wind turbine with a 600-kW generator will have a rotor diameter of around 144 feet. If you double the diameter, you will get four times as much power. Manufacturers often change their machines to account for local wind conditions.

What motor is used in windmill?

There are two main types of DC motor to consider, when choosing a motor for your wind turbine, but both work in essentially the same fashion. Both are constructed of wound copper wire and magnets.

### How big is the fan of a modern windmill?

Industrial wind turbines are a lot bigger than ones you might see in a schoolyard or behind someone’s house. The widely used GE 1.5-megawatt model, for example, consists of 116-ft blades atop a 212-ft tower for a total height of 328 feet. The blades sweep a vertical airspace of just under an acre.

How big is the generator on a wind turbine?

The picture gives you an idea of the normal rotor sizes of wind turbines: A typical turbine with a 600 kW electrical generator will typically have a rotor diameter of some 44 metres (144 ft.). If you double the rotor diameter, you get an area which is four times larger (two squared).

#### Can I use an AC motor for a wind turbine?

RE: Ac Motor used as a generator on wind turbine Any induction motor can run as an induction generator. You need to rotate it faster than the motor’s synchronous speed. Speed control of the wind turbine will be fairly critical.

How many acres do you need for a wind turbine?

In the United States, the direct land use for wind turbines comes in at three-quarters of an acre per megawatt of rated capacity. That is, a 2-megawatt wind turbine would require 1.5 acres of land.

## Can a car alternator be used for a wind turbine?

Turn a car alternator into alternative energy by building this cheap and easy homemade wind generator. If you can turn a wrench and operate an electric drill, you can build this simple generator in two days. You can use any vehicle alternator with a built-in voltage regulator.

How deep is the concrete base of a wind turbine?

A typical slab foundation for a 1 MW turbine would be approximately 15 m diameter and 1.5 – 3.5 m deep.

### Can a motor be converted into a generator?

You can use just about any motor to generate electric current, if it is wired correctly and you follow specific rules for its use. Modern AC induction motors are quite simple to wire as alternating current generators, and most will begin generating electricity the first time you use them.

Can I put wind turbines on my land?

Wind developers buy the turbines from the manufacturers, lease the land to place the turbines, construct and operate the development, and sell the electricity to a utility or distribution company. As a landowner, your business role will be to negotiate a contract for the lease of your land to a wind developer.

#### How much do landowners get paid for windmills?

On average, rental payments for the placement of a single wind turbine lease can pay landowners up to \$8,000 per year.

How big are the different sizes of windmills?

Windmills come in 6, 8, 10, 12, 14 and 16 foot sizes. (20 foot diameters windmill can be special ordered) Each size windmill has its own special motor and tower. Parts are not interchangeable between sizes. Remember that as the diameter of a circle doubles, the area of the circle is four times larger. Therefore, the 12 foot windmill has an area

## How many kilowatts does a wind turbine produce?

Large wind turbines, most often used by utilities to provide power to a grid, range from 100 kilowatts to several megawatts. These utility-scale turbines are often grouped together in wind farms to produce large amounts of electricity. Wind farms can consist of a few or hundreds of turbines, providing enough power for tens of thousands of homes.

How big is a typical Siemens wind turbine?

Its 3.6 MW SWT turbines of 107 m diameter (Figure 3.14) are now figuring prominently in offshore projects. Senior management in Siemens have indicated the end of a trend of exponential growth in turbine size (considering, year by year, the turbine design at the centre of their commercial supply).

### What kind of motor do you need for wind power?

Do-it-yourselfers build wind power generators almost exclusively with Permanent Magnet Motors, because they are widely available, reliable because of the nature of their construction, and start generating electricity at almost any RPM. The same cannot be said of some of other types of motors.
