The Exceed 4-MW+ gearbox has successfully completed long-time overload test in January at Moventas Research and Technology center in Finland. The results in this lifecycle simulating test were great, with highest loads being more than double of the nominal power. Vibrational and sound behavior, operational functionality parameters and load sharing on gears were on a high level.

The 4MW+ gearbox has gone through intensive verification process supervised by classification body, turbine manufacturer and Moventas experts. Next, the first gearboxes will be installed to wind turbine for further validation measurements in actual operating conditions.

The new 4MW+ gearbox continues the success of Moventas technology roadmap to implement the proven Moventas technologies with new innovations and design methods in the Exceed series to lower cost of energy in wind power generation. Moventas has already delivered over 1 GW Exceed technology gearboxes in the 3 MW+ class and the newcomer is another significant step to provide a relatively small size, light weight, and high torque density gearboxes to yet another power range of wind turbines.
