ANTARIS small wind turbines

Technical data ANTARIS 7.5 kW

Start of feed-in at 2.5 m/s wind speed after start-up, depending on the repeller. Wind turbine especially for inland locations with weak to moderate wind conditions. From an average wind speed of more than 6.5 m/sec., a repeller with a diameter of 4.40 m is used.

Generator

Permanent magnet rotor, brushless, gearless, maintenance-free
High efficiency due to extremely strong permanent magnets (NdFeBo permanent magnets, temperature resistant up to 150°)
Special ball bearings for safe absorption of radial and axial forces
3-phase three-phase current
Separate rectifier
Direction of rotation arbitrary
Voltage 0-1000 VDC
Start of feed-in at approx. 75 rpm
Power: 7,500 watts at 330 rpm & 400 VDC
Evenly increasing power curve
Weight: 87 kg
