Siemens Energy has developed the new gearless wind turbine for low to moderate wind speeds. The core feature of the SWT-2.3-113 wind turbine is an innovative drive concept with a compact permanent magnet generator. This type of generator is charcterized by its simple, robust design, requiring no power for excitation and control systems and don’t need sliprings. This results in high efficiency even at low loads. With a capacity of 2.3 megawatts (MW) and a rotor diameter of 113 meters the new wind turbine is especially suitable for deployment at locations with low to moderate wind speeds.
