Here is the nominal power curve for the 3.6 machine. Power curves vary between different voltages, and there have not been sufficient funds to produce a complete set of data, but we are working on it.
Notice that the diameter of the machine is large compared to it's
power output, and this gives it the torque to deliver good power in
windspeeds, when other machines are unable to catch as much wind.
We believe it is more important to have a steady, day to day supply of
amphours into the battery, than to have a high peak-power rating.
are parts of the alternator. The magnet rotor (top left) is
from iron. It runs on the main shaft. The blades are bolted
to the face this rotor. Inside the rotor are ferrite permanent
The magnets move past the laminated core of the stator which contains
coils of copper wire. On the right you can
see the stator being wound.
The alternator is heavy because it has many magnets and coils in it. Lighter alternators generally run at higher speed. These lighter wind turbines are noisier and wear themselves out sooner.

enlarged picture. The
wind turbine is protected against high winds by a simple, passive
which has been tested in winds exceeding 100mph, without incident.
As wind grows stronger, and maximum power is reached, the turbine is 'yawed' sideways from the wind. This prevents the blades from overspeeding. There a minimum of moving parts involved.. no springs.. no highly stressed components.(click)

This is a very simple machine that does what it is supposed to do. It is quite heavy duty and build to last a long time. The turbine is easy to install, with simple tools. I am most impressed with the turbine’s slow speed and quiet operation. It is refreshing to see that a modern wind generator can be manufactures that is absolutely quiet in its operation.
This is a very nice machine. I only wish someone in
could build something as good as the AWP. We could use the competition, to
say the least. And the low speed reliability. This is heavy metal, which
is right in line with my ideas on wind turbine design. Nice job!!!
