How To Create Wind Turbines For Home Use
Author: temp_44206
Utilizing wind energy is an attractive alternative to traditional energy for many homeowners today. A wind turbine can be used to generate a great deal of energy depending on a few different variables. The height you are able to reach with a suitable tower for a wind turbine is probably the most crucial to the amount of power it will generate. The general rule of thumb is to have the turbine at least 30 feet above anything within 500 feet of the tower to ensure the least turbulent wind. Wind becomes more turbulent the more objects it travels around, across, or into.
A tilt-up tower is constructed using metal tubing, is typically stabilized using 4 down guy cables and functions just as its name suggests. The tilt-up feature of these towers is more convenient for maintenance purposes but a bit more expensive then the previous tower above. The four-guyed cables are used to safely tilt the tower up from or down to the ground without the need for the tower to be climbed. Monopoles are the most expensive towers used for wind turbines and usually seen on large wind farms, they consist of a single structured tube, which tapers in from the ground up. Monopoles are the most aesthetically pleasing option for wind turbines but require the most amounts of steel, concrete and funds.
A small wind turbine for home use can be purchased or constructed. The cost of a pre-made wind turbine can be a substantial investment and it is recommended to spend a period of time taking wind measurements using an anemometer before deciding to buy. However, if you wish to construct your own wind turbine the cost can be reduced to only a few hundred dollars. A wind turbine is a device which converts wind energy to electricity using a low-RPM generator, therefore the most important aspect of constructing your own hinges on finding a suitable generator which is capable of producing 30 volts at 300-350 RPMs or better.
The potential savings with wind turbines for home use can be particularly substantial. With optimal conditions homeowners could see an 80% to 90% decrease in energy costs, but this is dependent upon consistent wind on the property. Utilizing a wind turbine is a green option that many homeowners can greatly benefit from making it an attractive decision not only for energy conservation but for substantial potential savings on energy costs.

What happens to the voltage of a generator (dynamo) when its rated rpm is exceeded? Will the voltage increase?
SCENARIO:
A 50/60Hz 1800 rpm 50k watt synchronous generator is coupled to a suitably powered driver. The driver spins the generator at twice its rated speed (3600rpm)…
FOLLOW-UP QUESTIONS:
(a) If you do not wish to lower down the driver’s rpm and leave it running as it is, can you then use a so-called step-down transformer to bring the generator’s voltage down to a usable rating (220-240v)?
(b) Will the “frequency” of the generator change as a result of increased rpm?
(c) Assuming that the driver will not breakdown and that the rated load of the generator is never exceeded, will there be a possibility that the generator will overheat if used continuously (24/7) say for a month or two or even longer? If NO, why? If YES, how do you explain so-called “baseload” generators?

Where can you buy a low RPM windmill generator?
I’m looking for the best, low-mid RPM cheap generator/alternator.?
In order to build a wind turbine for my home. What ever information would be helpful.
Also might anyone know how to convert a car alternator to work at lower RPM?
Thanks in advance.
Where could i order or buy a low rpm alternator for me to assemble a windmill generator?
Im setting up a windmill to save energy. i need a low rpm alternator, please help where could i buy it in US or Canada.
what is the correct working rpm for my app6000 portable generator?
I have a APP 6000 portable generator. Someone changed the engine rpm. Will I damage the unit if I run the engine at lower rpm. What is the correct/recommended setting?
You can increase RPM with belts or gearing! Cog belts are cheap.
You can use any GM alternator. The older the better because the new alternators have all the voltage regulation in them for the vehicle computers. You can probably get one at a junk yard for less than $40.
3600 rpm
A. The generator should have a built in voltage regulator which will adjust the field current and keep the voltage where it should be.
B. Frequency would double if the engine speed doubled. If the engine normally operates at 1800RPM for 60Hz output, doubling the speed to 3600RPM would create a 120Hz AC output.
C. I’d be concerned about the engine breaking down while operating at twice normal speed. If the voltage output remains the same, current supplied should not go higher. Check the ratings on the generator to see what its load capacity is. Some generators have a prime rating and a standby rating. Prime rating is for continuous permanent operation, standby operation is for short periods, several hours, perhaps a day or two at most.
