Technical Specifications ANTARIS 7.5 kW
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 6.5 m/sec. we use a repeller with 4.40 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
- Special blade design to minimise noise
- Approx. 5.30 m diamater (optionally 4.40 m > 6.5 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
