The Siemens-subsidiary's medium-speed "hybrid" transmission was chosen for F&S' Product Differentiation Excellence award for its cost-cutting "higher torque-to-weight ratio, shorter length, and lower mass" design.

"By decreasing the mass and increasing the torque-to-weight ratio of the drive-train, HybridDrive has resolved the issue of the inverse correlation between ROIs and power capacities of a wind turbine,” states F&S research analyst Krishna Raman.
