The result is a solution that offers high availability, compact size and lowest weight: the FusionDrive®.

        FusionDrive reduces CoE of wind power by 6%, offering 20-25% to grid parity thanks to its features, such as up-tower serviceability.
        Minimize total life cycle cost & boost annual energy production

        The FusionDrive has no slip-rings and no rotor windings. It has low cogging torque and no bearing currents. Its medium speed bearings have no smearing risk. Total amount of bearings is low, as no high speed bearings or generator bearings are needed. A common lubricant oil space provides controlled environment for force transferring rolling components. Gear stages and generator are perfectly aligned. No extra bearing forces or induced vibration appear. FusionDrive also has efficient air cooling system inside the generator.

        FusionDrive® requires minimal maintenance. Right from the beginning, FusionDrive® has been designed with easy serviceability in mind — FusionDrive can be completely maintained without an external crane. The gear and generator can be split, and all components are changeable in the nacelle. Small size, simplified turbine and great serviceability together bring down total lifecycle costs.

        Our open and innovative approach to customer needs combined with our pro-active R&D philosophy sets us apart from the competition. Our attention to detail, quality and serviceability is well known throughout industry as is our total lifecycle support services.

        We design custom made tidal gearboxes according to customer needs, representing the Moventas quality and reliability that's well known in the wind industry and emphasizing easy serviceability and lifecycle care.
      • Advantages

      • Lowering the cost of new energy with innovation

        Power Density

        In the constant pursuit of reducing the overall weight of the wind turbine mass, Moventas' engineers have discovered an innovative power / density concept based on proven designs. By designing it compact and extremely lightweight, our state-of-the-art gearbox provides a significant reduction of tower head mass. The need for drivetrain space in the axial direction is equally reduced by the power density concept. All reaction forces can be transmitted to the nacelle structure in an optimal way. The concept also ensures that there is no need for separate support structures for the generator.

        Torque density is used to measure gear performance. It states the level of torque one kilogram of material, used for gear unit, can carry. Lowering the mass influences also to gear dimension, so density correlates with mass. Moventas' expert gear design skills and application know-how with improved materials allow higher gear torque density for new gear unit designs.

        Noise & Vibration

        Moventas has successfully reduced the noise level of its gearboxes by improving tooth accuracy and choosing the optimal geometry and profile. Theoretical evaluation as well as on-site testing is used to eliminate any harmful resonance sounds of the structural elements. To achieve noiseless wind power, the gear unit must not vibrate. Therefore, our gear units are especially designed to prevent vibrations from passing through the gearbox fixing points to the foundation of the wind power plant.


        The Moventas product portfolio is the result of proven technology including modular components for all drivetrain solutions. Moventas planetary gear consists of our special knowhow of e.g. integrated bearings, case hardened ring wheels and Flexspider technology. Our product concepts are based on approved methods of regulatory agencies.

        All the gear units are verified by tests and measurements. Moventas has vast experience from prototype testing and qualification. During the last decade we have performed over one hundred modern wind turbine gear prototype test in MW class alone. Typically prototype gear units go through lifecycle and cold climate chamber tests. We also use virtual prototype environment to define drivetrain dynamics.
