Description
Introducing the latest evolution in small wind turbines. The AIR-X builds upon
what made AIR the world's #1 selling small wind turbine with new technology
previously found only in today's state-of-the-art mega-watt-class wind turbines.
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 ?lutter?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? smart controller allows it to actually
control blade rotation speed thus eliminating the buzzing noise commonly found
with the AIR 403 and 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? 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?
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? 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 blade speed
to 600 rpm, thereby significantly reducing turbine and tower loading while still
producing power. 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.
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.
