In the constant pursuit of reducing the overall weight of the wind turbine mass, Moventas' R&D engineers have discovered an innovative power / density concept based on proven designs. By designing it compact and extremely lightweight, our state-of-the-art gear unit and electrical machine provides the opportunity to significantly reduce tower head mass. The need for power train 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.
