A gearbox is used in wind turbines to increase the rotation speed given to the generator shaft and involves two or more gears that increase the speed from the rotational input. This increased rotation speed makes the wind turbine produce a higher electrical output power. Gearbox design involves some complexity in choosing gears as rotation speed and torque must both be managed. The interplay between torque and speed is demonstrated in this chapter by building upon the hand-crank generator of Chapter 1.
