The Siemens D3 Platform Siemens direct drive wind turbines of the D3 platform offer innovation through the consistent implementation of a common, highly efficient generator concept. With less than half the moving parts of a conventional geared wind turbine, the direct drive wind turbines improve performance, reliability and maintainability. In addition, the compacted design allows for cost-effective transportation and installation. SWT-3.0-101 Utilizing proven components such as the rotor of its geared counterpart, this wind turbine performs solidly even under the most extreme wind conditions. SWT-3.0-108 Innovative aeroelastic blades and a robust design allow for a larger rotor diameter. For lower cost of energy in high wind conditions. SWT-3.0-113 High energy output: With innovative blade design and the largest rotor of the G3 platform, this wind turbine gets the most out of moderate conditions while reducing noise emissions due to a lower rotor speed. This wind turbine is the ideal choice for most inland sites across the globe.
