All of these features are primarily
found within the body of the turbine. The new
microprocessor based speed control results in
increased performance, improved battery charging
capability and the reduction of “flutter” noise from
the machine. The controller allows for peak-power
tracking of the wind by optimizing the alternator's
output on all points of the cubic curve and then
efficiently delivers the energy to the battery. The
turbine’s smart controller allows it to actually
control blade rotation speed thus eliminating the
buzzing noise commonly found with the AIR 403 a
nd
303 in high winds. Furthermore, a new series of
carbon-reinforced blades with a modified pitch angle
further increases power production.
The new electronics are a considerable improvement
over the AIR 403 controller that consists of
diode-rectification and a simple off/off voltage
switch.
Much Lower Noise: Previous AIR wind modules relied on
their aero-elastic blade design for protection in
high winds, causing loud flutter noise in winds
above 35 mph (16 m/s). AIR-X’s circuit monitors the
wind speed and electronically slows the blades as it
reaches its rated output preventing it from going
into flutter. This results in a much quieter wind
turbine. In high winds, the AIR-X will continue to
produce power at a reduced level until the wind
decreases, at which point maximum output will
resume. The Benefit: Quieter and neighbor friendly
operation.
Improved battery charging: Previous AIR designs
required 300-400 amp hour battery banks so the
trickle charge of the wind turbine could be
adequately absorbed. The AIR-X’s charge controller
periodically stops charging, reads the battery
voltage, compares it to the voltage setting and if
the battery is charged, it completely shuts off all
current going to the battery. This function is
performed within a few milliseconds. The closer the
battery is to reaching its full state of charge, the
more often the AIR-X’s circuit repeats this action.
This means any size battery bank from 25 to 25,000
amp hours or higher can be charged safely. When the
battery has reached its charged state, the AIR-X
will slow to an almost complete stop. Only when the
battery has dropped below its voltage set point will
it startup and resume charging. The Benefit:
Extended battery life, no overcharging.
Lower stress design: AIR-X limits power on the input
side of the electronics by controlling the torque
from the blades. The power no longer has to be
dissipated by the electronics resulting in lower
stress on the circuit, bearings and other materials.
Furthermore, stress on wind turbines occurs
primarily in high winds. Under these conditions, the
electronic stall design reduces the speed to 600
rpm, thereby significantly reducing turbine and
tower loading. The Benefit: Greater confidence in
turbine operation in high wind conditions without
manually operating the stop switch. Note: A manual
stop switch control is an available option for the
AIR-X.
Improved resistance to the effects of the sun, wind
and water: AIR-X marine has vastly improved body
preparation and applications of the marine paint
during manufacture, ensuring durable powdercoat
protection of the body and internal components, even
when subjected tot he most extreme sun, wind and
water conditions.
Design changes are primarily found within the body of
the turbine:
New microprocessor-based controller.
New
"wave washer" combined with looser bearing-to-body
tolerances are incorporated into the face bearing
set. This results in lower compression on the
bearing/race, with quieter running and lower startup
speed. It also lowers stress on the bearings and
shaft when subject to twisting forces during normal
operation.
New series of carbon reinforced blades.
More robust tower clamp and yaw assembly for stronger
and more secure tower mounting.
Improved powdercoating protection, as the body is acid
etched and treated with alodine before powdercoating
with a UV resistant marine paint.
All hardware is a marine grade stainless steel.
Assembly includes "Tef-gel" compound to resist
corrosive activity between dissimilar metals like
stainless steel and aluminum.
Body and electronics are completely sealed for
prevention of water ingress, even under brief
immersion conditions.
