TURBINE PERFORMANCE
TURBINE TECHNOLOGY Power Generation: The Lakota turbine uses an 8 pole, 36 slot, 3 phase alternator with 10
winding leads. This allows 4 separate field adjustable settings to be made that
will optimize it's output and match it's performance to low, medium, high or
severe wind regimes. Consult your authorized Lakota dealer for details. Blades: Lakota's aerospace grade uni-directional carbon fiber blades are not to be
confused with carbon matrix or carbon reinforced plastic blades. Unlike plastic
with powdered carbon blades that bend and flutter, the carbon fibers in the
Lakota blades are 7 times stiffer than common steel, and carry the loads from
tip to root. This allows the Lakota to harness far more energy annually than
comparable similar wind turbine generators. In addition, the increased output
substantially lowers the overall cost of energy despite a slightly higher
initial purchase price. Coatings:
Power Output:
Sea Level: 900 Watt nominal at 28.8 mph
500 Watt nominal at 21.5 mph
Peak Power maintained (up to 1200-1500Watts) in all wind above 30mph
Users have reported over 1500Watts at 100Amps

Cautionary Note: Comparison of test curves and power data
is highly dependent on location, tower height, turbulence, obstacles, humidity
and other factors. Please consult an expert before drawing conclusions or
accepting manufacturer claims. A good independent reference is Mike
Klemen's Test Site in North Dakota.
These charts shows the superior performance of the Lakota blade technology. (see
also Blades technology below) With a smaller diameter, light weight and very
stiff blade technology and much lighter system Lakota out performs higher rated
competitors in medium to high wind conditions. That's because Lakota does not
hide from the wind but maintains its full performance throughout its entire
flight envelop. Competitor systems tend to turn off or turn away from the wind
and reduce their output. Above 30mph LAKOTA continues to produce peak power in
excess of 1500W and some users report up to 1800W at 100amps without damage to
either electrical or mechanical components. Rain, snow, sleet or storms the
Lakota SC turbine is made to take it all and continue to put out the power.
In addition, since the blades are very light they can take advantage of wind
gusts that heavier blades can't because their inertia is too high to react
before the gust is over. Over time this amounts to considerable extra energy
extracted from the same column of air.
The Lakota generator has a high power to weight ratio. It uses a single stator,
rare-earth neodymium iron boron permanent magnet in a cast aluminum casing with
stainless steel fittings. The upward furling mechanism ensures the Lakota will
not "Hide" from high winds but continue to put out up to two times
it's rated power without damage to its electrical or mechanical components. It's
precision components are designed for long life. We recommend at least a 60-100
amp DC circuit breaker be used with all installations.
Lakota turbines are sealed units and require only annual inspection. No
lubrication or overhaul maintenance schedule is required during the life of the
generator. (approx. 15-20 years). Marine or desert installations may need more
attention to surface corrosion and leading-edge tape on the blades. Helicopter
grade leading-edge tape is replaceable if abraded by fine debris or sand. Lakota
field units have survived 120mph storms while other units nearby have self-destructed.
Vehicle mounted test units continue to output maximum power at over 70mph with
no damaging effects.
