Wind turbines with direct drive generators today have a 15% market share worldwide, although the cost level is higher than for conventional solutions with gear-box and high-speed generator. The new direct drive generator - the NewGen - has the potential to reduce the weight and thus the cost of the generator installation by 70%. This is mainly achieved by applying a novel mechanical solution, which drastically reduces the stiffness requirements and therefore permits a larger diameter of the generator. In this way both the amount of electrically active material and the amount of construction material are reduced. Thus the total wind turbine cost will decrease by roughly 20%. The reduced cost level will increase the potential for and use of wind power, which is highly relevant for the European and world supply of energy and for the environment.
