greencarcongress - Siemens Energy launched its new 6-megawatt (MW) ...features the Siemens direct drive design with 50% fewer parts than comparable geared wind turbines. With a towerhead mass of roughly 350 tons, the SWT-6.0 is the lightest machine in its class. This combination of robustness and low weight significantly reduces infrastructure, installation and service costs, and boosts lifetime energy output and profitability, Siemens claims.
...The direct-drive wind turbine is offered with two different rotor blades. The SWT-6.0-154 features the largest rotor blade in the 6-MW class, using the new 75m B75 Quantum Blade. The SWT-6.0-120 is equipped with the proven 58m B58 rotor blade.
The entire electrical system of the new 6-MW machine—including the medium voltage system and the full converter—is now enclosed in the nacelle, which also features an integrated helicopter-hoisting platform in the rear.... Read on at: greencarcongress
