- High system efficiency, 96-97%
- 6MW to 16MW
- Dual Rotor Single Stator Radial Flux Configuration
Business Benefits
- Reduced upfront cost due to elimination of Rare Earth Magnets
- Reduced maintenance cost due to elimination of gearbox
- High energy production due to higher efficiency
- Smaller generator cooling system requirement due to reduced losses
Rare Earth Eliminated
- Save around 1000 Carbon Credits per MW by replacing Rare Earth Magnets
- A Direct Drive Wind Generator uses 650kg of Rare Earth Magnet per MW
- Mining of Nd and Dy produces pollution equivalent to 1.56 tons of CO2 for manufacturing one kg of Rare Earth Magnet
