  • 7. • Number of blades (commonly two or three) • Rotor orientation (upwind or downwind of tower) • Blade material, construction method, and profile • Hub design: rigid, teetering or hinged • Power control via aerodynamic control (stall control) or variable-pitch blades (pitch control); • Fixed or variable rotor speed • Orientation by self-aligning action (free yaw) or direct control (active yaw) • Synchronous or asynchronous generator (with squirrel-cage rotor or wound rotor - Doubly Fed Induction Generator (DFIG) with gearbox or direct drive generator. DESIGN CONSIDERATIONS
