The D400 has been developed specifically to operate in close proximity to people.
The noise and vibration usually associated with small wind turbines has been
designed out of the D400. This has been achieved by making the turbine run
relatively slowly for a given electrical output. In a given wind speed and a given
electrical output, the D400 rotates at less than one quarter the speed of some
competitor units. Combined with its rugged engineering and advanced computerdesigned
air blades, this makes the D400 the most reliable and benign turbine of
its class currently available.
The air blades are precision injection-moulded from glass reinforced nylon and as
well as featuring taper and twist incorporate a special low-Reynolds airfoil section
which varies continually in camber from tip to root. Because of the production
method used, the blades are extremely consistent in terms of mass and can be
replaced singly should damage occur without losing turbine balance. The
alternator and yaw shafts are precision-ground from 316 grade stainless steel,
and the D400’s body is a robust aluminium alloy casting.
The bearings are high quality and generously sized, and are protected by
twin-lipped radial shaft seals.
The tail is formed from aluminium sheet into a shallow ‘S’ section in order to
impart stiffness and prevent resonance. All aluminium parts are etched,
alachromed and finished in a tough polyester powder coat.
The D400 utilises a 12-pole, 3-phase axial field alternator of very high efficiency. It
comprises two large annular magnet rotors with stator coils positioned in between.
The stator coils themselves are wound from heavy gauge copper and are
encapsulated in a heat-conductive resin. This in turn is bolted to a machined shelf
within the aluminium housing, so ensuring excellent heat dissipation from the
machine. A combination of the advanced air blade and alternator design delivers
unparalleled efficiency in low wind speeds together with the ability to produce
sustained high outputs in high winds.
Eclectic Energy Ltd’s attention to
design and quality should ensure
your D400 gives years of
trouble-free service.
