After eight months of testing and verification, FusionDrive, the gear and generator combination is now a validated drivetrain. The small and lightweight combo has proven to reach 96.6% efficiency.
The gear and generator combination is a joint effort of Moventas and permanent magnet generator supplier The Switch. FusionDrive with 3000kNm shaft torque carrying capacity has recently completed comprehensive factory verification process at the Moventas R&D center in Jyväskylä, Finland. FusionDrive’s overall efficiency reached a 96.6% already in 65% of the operation nominal. The full load tests of the FusionDrive showed good dynamic behavior and an overall sound power level of < 96 dB(A) in all operation phases. The combo’s vibration tests also exceeded expectations. In addition to normal testing the verification process was modified to verify also FusionDrive’s serviceability. A complete FusionDrive service without an external crane is now proven to be possible. This reduces maintenance and repair lifecycle cost – according to Moventas’ calculations; by as much as 15%.
