Delivering 3.3 MW, SWT-3.3-130 has 130 m dia rotor and optimizes energy extraction in low- to moderate-wind velocities. Direct-drive PMG generator operates with permanent magnets to enhance output, servo motors ensure precise rotation of nacelle, and hydraulic cylinders in rotor hub enable exact adjustment of rotor blade angle. Under turbulent wind conditions, ends of B63 aeroelastically tailored blades cushion and absorb wind pressure to limit static loading of nacelle and tower.
