The efficient HybridDrive by receives Frost & Sullivan’s Global  Product  Differentiation Excellence Award 2013

The modular design of the HybridDrive is lauded for minimizing complexity and cost of service for wind energy producers.

Based on its recent analysis of gearboxes for the wind energy market, the global research organization Frost & Sullivan conferred the 2013 Global Product Differentiation Excellence Award to Winergy’s HybridDrive due to its higher torque–to-weight ratio, shorter length, and lower mass leading to reduced overall costs for the wind turbine installation.

Winergy’s HybridDrive combines a two-stage-planetary gearbox with a permanent-magnet generator into an integrated drivetrain resulting in length reduction of 35 to 50 percent for the entire drivetrain. The system has a power transmission efficiency of more than 96.5%.

“Thus, Winergy manages to decrease the weight of the drivetrain up to 10 percent for larger turbines” says Krishna Raman, a Frost & Sullivan Research Analyst.

Customers of the HybridDrive can choose between journal bearings and standard antifriction bearings, whereas the former results in less abrasion and an increase of the wind turbine’s availability.

Naturally, the design of the HybridDrive complies with the 2010 “GL Guideline for the Certification of Wind Turbines.”

“By decreasing the mass and increasing the torque-to-weight ratio of the drivetrain, HybridDrive has resolved the issue of the inverse correlation between ROIs and power capacities of a wind turbine,” noted Raman.

Winergy sets a milestone in the development of wind turbine drive trains with the Hybrid Drive, and since October 2013 the 3MW HybridDrive has been installed in a Wind-to-Energy (W2E) turbine in northern Germany and has produced more than 4 Mio. kWh.
