The blades, the hub, and the main shaft of a wind turbine harness the kinetic energy of the wind and convert it into rotational mechanical energy. The speed of this rotation is too slow to drive the generator efficiently, so a gearbox converts the high-torque and low-speed mechanical energy of the main shaft into the…
Video : Wind Turbine Yaw Movements and Gyroscopic Forces Under normal operational conditions, yaw movement may occur when the rotor is stopped or when it is turning. When the rotor is stopped, the force applied by the yaw drive needs to overcome only the inertia of the nacelle and the frictional forces at the yaw…
