Product Details

500kW to DIRECTWIND

The DW61 – 500kW builds on the advantages of s market leading DW54. The DW61 significantly increases kWh output through a larger rotor diameter, which is the result of the latest aero dynamical blade design and advanced control technologies. The DW61 is designed for wind class IEC IIIA conditions and retains the tip heights of 77 and 100 meters, which have proven favorable to planning authorities.

Offers a highly efficient product range based on direct drive technology with a high yield and low cost of energy. The combination of proven direct drive technology and advanced control features makes’s DIRECTWIND a

First-class choice with regard to energy yield and reliability.

Individual pitch control : Reducing the loads on the main turbine components. 

Direct drive:
Fewer rotating parts reduce mechanical stress, leading to a lower maintenance need and therefore superior availability levels.
 Redesign nacelle:
Improved spacious nacelle design for easier servicing at maximum health and safety standards

New tower design:
In accordance with the latest IEC standards.
 New rotor blades:
Latest aero dynamical design, resulting in high efficiency and low noise levels.

In the DIRECTWIND turbines, the rotor directly drives

the synchronous generator without the use of a gearbox. Eliminating the gearbox means that the number of rotating components is reduced and therefore, the wear

and tear on the parts, leading to a lower maintenance need

Energy generated from the turbine is fed into the grid via

a modern back-to-back full-power converter, which controls the power output
