Siemens attacks Enercon's monopoly

The somewhat complicated type designation of the prototype specifies its most important characteristics: a capacity of 3 MW, a rotor diameter of 101 m and the most important feature, the gearless direct drive (DD).

In July 2008, it became obvious that Siemens would soon venture down this road after the company started testing two conventional 3.6 MW turbines in Denmark from which the gearbox had been removed. Both were equipped with new generators that achieved a high output despite the low rotation speed.

The test results were obviously so good that Siemens soon designed a new turbine type, which will go into series production in 2010. The generator comes from the company itself. It will be produced by the Business Unit Large Drives of the Siemens Industry Sector.
Enercon still has one kind of monopoly because the company is the only manufacturer worldwide that is capable of producing large numbers of direct drive turbines in the 2 to 3 MW range. This monopoly will now be attacked by Siemens.
