As to how the size and arrangement of your blades, you ll need to match this
to the type of generator you have, the height of your wind turbine, the target
power output of your wind generator, and most importantly your budget.
Typically, this task is accomplished by a permanent magnet dc motor. As a
general rule of thumb, you want a motor that will produce a large current and
voltage at the lowest speed (rpm) possible. Being aware of any potential issues
before you start your build will save you not only time and money, but more
importantly frustration that could derail your plans. And the best part is that
these kits are very inexpensive.
Building your own home wind turbine can be a great educational experience
that s not only financially rewarding, but a fun DIY project. If you want to
build them yourself, they can be fabricated from PVC or ABS pipe, wood,
aluminum, or even fiberglass or carbon fiber. Also, pay particular attention to
the bearings in the motor. It converts the power of the wind to electrical power
that you can use.
The generator portion is the heart of any wind turbine. And while it s
certainly possible to construct your own blades cheaply, the prefabricated blade
kits are are very inexpensive and can help you start generating power much
sooner without the hassle of building them. Since the motor will be subjected to
high thrust and rotational loads, you ll want one that can handle these types of
loads. Not only that, some of the blade kits that are currently available come
with a nose cone, thus saving you the hassle and expense of fabrication this
very important piece. Look for a motor that generates it s voltage at speeds
that are 300 rpm or less if you can. There are a few reasons for this, but one
of the more important ones is that slower speeds mean less maintenance. Just
remember to have stainless steel
bending manufacturers a good set of plans and sources for the required parts
before you start. Or even worse, have a machine shop do it for you. Or they can
also be inexpensively purchased as prefabricated units. We feel that because of
these benefits, prefabricated blade kits are probably the best choice for most
people, and well worth looking into.
There are a couple of different paths you can take for the blades used on the
wind turbine.If you re going to build a home wind turbine, you ll be much
further ahead if you thoroughly research each of the individual components
involved in a DIY wind turbine system. The generator portion, typically a
permanent magnet dc motor, and the blade system. Doing your homework ahead of
time will help to make your project a huge success. Often, these blades come
with hub mounting hardware too, which eliminates the need to make the hardware
yourself. Here, we ll take a look at a couple of the more important pieces of
the wind generator system
