Siemens Energy launched a direct-drive gearless wind turbine for low to moderate wind speeds. The core feature of the new SWT-2.3-113, says Siemens, is a drive concept with a compact permanent magnet generator, which is characterized by its simple design, requiring no excitation power, slip rings or excitation control systems. This results in high efficiency even at low loads, boasts the company. With a capacity of 2.3MW and a rotor diameter of 113 m, the turbine is fitted with the new Siemens B55 Quantum Blades, which aim to boost efficiency and optimize performance.
