On average, close to 11.3 GW of direct-drive wind turbine capacity were added year-on-year between 2011 and 2016. However, an average of around 15.7 GW of direct-drive wind turbine capacity is estimated to be added year-on-year between 2017 and 2021. The market is witnessing an uptake in the direct-drive technology due to higher failure rates in some of the wind gearbox components.

Some 67% of wind gearbox failures are due to bearings. The axial cracks formed during high- or intermediate-speed stages are the leading cause of bearing failures. The other most common failure is due to gears. This component fails because of poor lubrication, heavy load, tooth interface, breakage in gear teeth, misalignment, lack of gearbox housing compliances, and surface factures.
The other general reasons for failure are inappropriate design in gearbox unit, extreme weather situations, underestimated design load, torque load, manufacturing errors, misalignment of component in shaft, damage during transportation and assembling or installation, etc.

Gearbox is the equipment that connects blades to the turbine, and it is this which, combined with a generator, generates electricity from wind energy. The main types of gearbox used in the wind industry are planetary gearboxes and helical gearboxes.The value of the global gearbox market increased from $3.42 billion in 2011 at a Compound Annual Growth Rate (CAGR) of 3.2% till 2016. The main reason for the growth was due to the increase in annual wind capacity additions primarily in the Asia-Pacific region.
During the forecast period, the average cost of a gearbox unit is expected to decline due to economies of scale and maturity of wind gearbox technology. As a result, the value of the global wind gearbox market is expected to decline at a negative CAGR of 2.5% between 2016 and 2021. The market is dominated by independent wind gearbox suppliers, namely China High Speed Transmission Equipment, ZF Wind, and Winergy.
