Moventas said the 2-3MW Exceed gearbox provides 20% more torque density, with a 10% reduction in size compared with its previous 3MW gearbox, which features in Acciona turbines.

The Exceed uses new gearbox technology that provides a high 135 Newton metres per kilogramme (Nm/kg) torque-to-mass density, compared with the roughly 60Nm/kg as supplied by Moventas in 2006.

Torque density is a key focus for research and development for Moventas and its main gearbox competitors, as it is a key performance indicator in the industry.
