Gearbox - Not present in every wind turbine

The majority of wind turbine manufacturers use gearboxes that can change the speed and torque between the rotor and the generator. The rotor shaft rotates at low speed with high torque, while the generator rotates quickly with low torque. Systems with gearboxes are still manufactured, but numerous models are also available second-hand on the secondary market. However, some companies also rely on gearless concepts for the manufacture of their systems. Which technology is used, when and where depends entirely on the conditions under which a wind turbine is to operate. The price also plays a role, because a wind turbine with gearbox - whether used or new - is available at a lower price than its gearless counterpart. Although geared turbines require more maintenance, they are just as suitable for offshore use as wind turbines without gearboxes.
