Exceed 4MW+ gearbox passed long-time overload test with excellent results

Moventas has been developing a new product to the Exceed technology. Exceed product platform was launched in 2014 with a 3MW+ gearbox with the best weight/nominal torque ration in the market. A new Exceed 4MW+ will now be joining the product family.

The Exceed 4MW+ gearbox 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 excellent 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 3MW+ class and the newcomer is another significant step to provide small size, light weight and high torque density gearboxes to yet another power range of wind turbines.
