M28 Giromill wind rotor with 3/6 Darrieus/Savonius blades for DOMUS wind generator

100,00€ – 190,00€

Our GIROMILL M28 vertical axis rotor with double DARRIEUS/SAVONIUS profile allows you to maximize efficiency: the Darrieus profile to capture a large volume of air and work at high speeds; the Savonius profile to lower the start-up and increase the torque.

Available with 3 blades (3 + 3: DOMUS Wind Generator Extension Kit) or 6pale (6 + 6).

Description

The wind rotor is, together with the alternator, the heart of a wind system. It is generally made up of a hub on which a certain number of blades are anchored.

Our M28 vertical axis wind rotor with double DARRIEUS/SAVONIUS combined profile allows you to maximize efficiency: the Darrieus profile captures a large volume of air and work at high speeds; the Savonius profile lowers the start-up and increase the torque.

Also available in 6-blade version (6 vertical Darrieus blades / 6 horizontal Savonius  blades), which allows you to capture twice the wind in the same volume unit, doubling the power while the SAVONIUS/DARRIEUS hybrid rotor improves performance even at low revs.

Self-braking: due to its intrinsic aerodynamic nature, the Savonius profile is self-braking. A vertical axis wind turbine does not need a brake in case of turbulence. As the rotational speed increases, in fact, the blade, which is geared against the wind, acts as a brake, limiting and stabilizing the rotation speed.

Package contents:

  • 3/6 Darrieus blades + 3/6 Savonius blades
