Moventas and The Switch provide offshore output in onshore size - FUSIONDRIVE™ COMBINES WIND TURBINE GEAR AND GENERATOR

VANTAA, FINLAND--(Marketwire - September 21, 2010) - Moventas, one of the biggest wind gear manufacturers in the world, and The Switch, the leading supplier of megawatt class permanent magnet generators and converter packages, both Finlandbased, have collaborated to develop a revolutionary power train solution for wind turbines.

FusionDrive™ integrates a highquality gear, traditionally the largest component in a turbine, manufactured by Moventas and a reliable permanent magnet generator by The Switch in an innovative way - together smaller in size and lighter in weight than any other solution in the market.

"The lower the nacelle weight, the more cost competitive the turbine. Nacelle weight relates directly to both foundation and construction costs of the turbine as well as manufacturing, transport and assembly costs in the whole supply chain," says Jukka Jäämaa, Moventas CEO & President.

The FusionDrive™ integrated solution with perfect alignment between gear stages and generator and an integrated lubrication system simplifies the nacelle structural design. The low number of bearings, low cogging torque and the construction with no current passage through bearings, sliprings or rotor windings also contribute to the proven reliability of medium speed technology. FusionDrive™ is designed on a scalable platform that extends from 3 MW to offshore class.

"For wind park owners, reliability in practice means high availability and lower operation and maintenance costs. In addition, FusionDrive™ guarantees optimized efficiency, even at partial loads," says JukkaPekka Mäkinen, CEO of The Switch.
