Product Information

The D400 is a new direct-drive wind generator, designed for a variety of marine, rooftop or terrestrial applications. It is exceptionally quiet and vibration-free in operation, qualities that are of paramount importance for any wind generator operating in close proximity to people. The D400 is available in white, or low visibility black as the StealthGen.

The D400 features a powerful 3-phase alternator, and computer-designed rotor blades optimised for low speed, user-friendly operation.

This innovative machine is extremely efficient in low wind speeds, yet is capable of sustained high power outputs of up to 500 watts in higher winds.

Distinctive and elegant in design, the D400 is superbly engineered for long, trouble-free service, and is available in either 12 or 24 volt variant.

Features:

  • Specifically designed for installation on boats, and on or near buildings
  • Almost silent in operation
  • Smooth running with optional integral anti-vibration mount
  • Unparalleled low wind speed performance
  • Low tip speed ratio, 1.1 metre diameter rotor
  • Advanced variable camber airfoil blades
  • Robustly engineered for long trouble-free service
  • Highly efficient, low-speed, 3-phase axial field permanent magnet alternator
  • Excellent heat dissipation with heavy duty encapsulated windings for sustained high output operation
  • Aesthetically attractive design • Corrosion-resistant materials used throughout
  • Available in 12 or 24 volt DC
  • Turning circle - 585 mm
  • Mounting tower 2’’ O/D tubing
  • Weight 15 kilograms


  • 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 computer designed 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-inductive 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.
