renewable products

We offer a number of products for both on shore and off shore wind generation of energy.

The products range from major components to completly assembled turbines.

The turbines feature:

Single main bearing & generator in one

The turbine is based on the single main bearing concept. The bearing has a large diameter that enables it to bear the enormous force of the rotor: there is no central shaft. The bearing component is integrated into the generator and is possible because the turbine uses direct-drive technology. This innovative design not only creates a compact and lightweight permanent magnet direct-drive generator; it also results in significant savings in logistics, foundation and support structure costs.

External air generator cooling

The exterior shell of the generator is covered with small surface extensions to transfer the heat to the cool air. This avoids using a powerful, potentially unreliable cooling system.

Light weight

Innovative design and new materials have resulted in a easy to instal, large, lightweight turbine with a capacity of 5 MW.

Direct drive principle

The turbines are based on the direct drive principle, thereby dispensing of the need for gearboxes. Gearboxes pose a significant problem for offshore wind turbines because the torque of multi-megawatt wind turbines is enormous. In contrast, gearless turbines require less maintenance, are more reliable and therefore boast higher operating availability.

Permanent magnets in the generator

As no additional electricity is required to magnetise the rotor coils, there is no need for generator `brushes` to transfer this electricity. This increases both efficiency and reliability because the rotating part of the generator contains no electrical systems.
