The heart of innovation button
The GS WIND generators , synchronous , multipole permanent rare earth magnets increase the energy yield by getting the most out of the wind. The adoption of permanent magnets determines the elimination of electrical excitation of the generator coils and ensures considerable advantages such as :
- Reduction of sliding contacts between rotor and stator , thus less wear .
- Elimination of maintenance operations for the replacement of the brushes of the sliding contacts , thus greater reliability .
- Compactness of the spacecraft due to greater optimization of space .
- Elimination of electrical negative absorption due to ‘ electrical excitation of the coils , so most production absolute terms .
The cooling system is guaranteed by circumferential fins , placed on the entire outer surface of the generator that are lapped by the wind ensuring optimum cooling .
