The Siemens Drive Technologies’ Direct Drive Wind gearless wind generator is comprised of individual, preassembled generator segments. It is able to offer a high degree of flexibility in the implementation of a wide range of turbine solutions and system concepts. The generator, designed as a multi-pole, permanent magnet synchronous machine, is characterized by a high level of reliability and is thus particularly suitable for operation under rough conditions and in isolated locations. The modular platform concept features standardized components and a high level of mechanical integration, resulting in simplified logistics and installation and enabling greater levels of efficiency to be achieved. Based on a modular technology platform, the generator is not manufactured as a single unit, but is instead put together from preassembled segments. This enables extremely versatile realization of the most varied plant designs with a selection of different bearing concepts, voltage levels and cooling methods from a modular component range. Both internal and external rotor concepts are possible, and outputs of up to 10 MW can be attained. With the Norwegian wind turbine manufacturer Blaaster Wind Technologies, Siemens has both a pilot customer and a development partner able to look back on numerous years of experience in the wind energy market at its side. The first joint prototype of the Direct Drive Wind turbine from Blaaster including the integrated fully segmented wind generator from Siemens Industry, was installed in summer 2012 in Valsneset, Norway.
