AICROD 6.5 kW Turbine

Technical Specifications

Working grid feed in at 2.5 m/sec wind speed after start up, depending on the repeller. Purpose built for inland areas with low untill moderate wind speed. From an average wind speed with 7.5 m/sec. we use a repeller with 4.0 m diameter!

Generator

  • Permanent-magnet rotor, brushless, gearless, maintenance-free
  • Extremely strong permanent magnets for a high level of efficiency (NdFeBo permanent magnets, resistent to temperatures up to 150° C)
  • Special ball bearings for reliably taking up radial and axial forces
  • 3-phase current
  • Separate rectifier
  • Either direction of rotation
  • Voltage 0-1000 VDC
  • Start of feed-in at approx. 75 rpm
  • Power: 7.500 watts at 330 rpm and 400 VDC
  • Evenly rising power curve
  • Weight: 87 kg
  • Aluminium housing, surface cooling, base anchoring
  • Protection class IP56

Rotor

  • Hub connection with aluminium flange and pressure-relief plate
  • Stainless-steel screw connections with locknuts
  • Three rotor blades in glass-fibre / carbon-fibre laminate
  • Computer-designed aerodynamic profile
  • Winglets on blade tips to minimise noise
  • Approx. 5.30 m diamater (optionally 4.0 m > 7.5 m/s average wind speed)
  • Weight of each blade: approx. 9.2 kg
  • Dynamically and statically balanced
  • Direction of rotation anticlockwise viewed from front
  • Max. rotational speed 300 rpm
  • GRP spinner cap
  • Rotor colour to client specification

Support element comprising

  • Wind vane (weatherproof HDPE, off-white, slightly transparent)
  • Square stainless-steel tube as support element
  • All screw connections in stainless steel and fitted with locknuts
  • Steel bracket as support for generator, configured for plug-in connection with azimuth bearing, fully galvanised
  • Protected by patented rotor-blade positioning system
  • Mast adapter with flange connector (tube 139 mm)

Storm protection

  • Rotor-blade positioning (“helicopter position”)
  • Voltage monitoring with 12.0 kW braking resistance
  • Generator short-circuit

Control cabinet

  • Control system with Turbine Power Curve
  • 3-phased grid-feed in with Smart!wind Inverter 7.5 kW
  • Control electronics with 3-phased turbine controller
  • Connections / plug connectors protected against polarity reversal
  • Controlling of the 3 alternator phases during turbinemode
  • Reset switch with key (removable)
  • Emergency-OFF switch
  • 6.5 kW braking resistance
  • Rectifier, display etc.
