Technology

The patented DirectDrive technology is at the core of LEITWIND wind turbines. By directly connecting the rotor to the generator, the system operates without a gearbox.

The drivetrain architecture includes fewer high-speed rotating components, resulting in a simplified design and a reduced number of drivetrain elements.

The reduced number of mechanical parts subject to wear means greater efficiency and reliability, as well as reduced maintenance times.

This technology, combined with specific optimised power, makes LEITWIND wind turbines also particularly suited for areas with little wind.

LEITWIND wind turbines are designed using a modular concept, divided into distinct groups of tower heads: the hub, the generator and the main frame.

This approach provides a high level of standardisation among the different wind turbine models.

The Direct Drive generator is integrated centrally into the supporting structure, offering a highly compact, robust design.

The main frame, which is common to all models, is designed to guarantee safety and easy access from the inside to all those parts in need of maintenance.

Modularity also offers significant advantages when it comes to production, maintenance and also logistics, allowing turbine installation even in places that are hard to reach, such as mountain areas.

LEITWIND generators are different from one another due to the size of their external diameter and their axial length. These generators are optimized according to rated power and to the diameter of the LEITWIND wind turbine rotor.

All LEITWIND generators share the same design: multipole alternators with permanent magnets for increased efficiency, and compact thanks to the flux concentration.

The alternators also have segmented active parts, a technology patented by LEITWIND.

This segmentation allows reliable modular production and means that generators can be maintained directly in the tower head.

LEITWIND designs and manufactures the blades for its wind turbines entirely in-house.

The blades consist of a load-bearing structure with prefabricated root components and aerodynamic shells. They are made of glass fiber-reinforced epoxy resin using RIM technology.

The modular design and production approach results in each component having a single specific function and relatively compact dimensions. These two key features facilitate quality inspections during manufacturing and ensure a simpler and safer final assembly process.

As a direct result, LEITWIND blades achieve a high level of reliability throughout the operational life of the wind turbine, as demonstrated by all models currently in production, including the LS39, LS44, LS39 Tifonica, and LS20.

The combination of alternator and IGBT technology used on LeitDrive converters ensure excellent grid compatibility.

LeitDrive frequency converters, developed by LEITWIND, are flexible and adapt to the grid code requirements of operators, and to a wide range of connection parameters.

These frequency converters are able to manage reactive power, in accordance with the power grid, and can also support weak or unstable grids.
