Moventas says the FusionDrive wind turbine drivetrain has proven to work well during testing at the company's research and development center in Finland.
Already in commercial production for DeWind, FusionDrive is a joint effort of Moventas and permanent-magnet generator supplier The Switch. Moventas says the product is an advanced gear and generator combination, and it is small and lightweight; a 3 MW FusionDrive weighs 35 tons and is two meters long and 2.3 meters wide.
After a period of successful cold-climate testing, two FusionDrive units are now driven for some five weeks in various load conditions. At full load, the company says, the FusionDrive has shown "ideal" noise and vibration performance.
The FusionDrive load test run will be followed by an analysis phase, serial drive and a disassembly demonstration in an event for customers, media and other interest groups in June.
