14:30 - 16:00 Innovation in wind turbine drive trains
Turbine technology  
Onshore      Offshore    

Room: Montmartre

This session will share new concepts to reduce failures/improve behavior cost-effectively:

  • New configuration of bearingless permanent magnet machine with multiple modules for direct drive to reduce bearing failure
  • Coupled magnetoelastic model of a multipole permanent magnet generator in no-load conditions to reduce weight
  • Potential of MgB2 superconductors on direct drive generators
  • Alternative Wind Turbine Drive Train with Power Split and High-speed Generators 

Learning objectives

  • Delegates will be able to list problems associated to generator systems in direct-drive WTG and identify a new bearingless concept
  • Delegates will be able to list design problems inherent to scaleability and identify a model to capture dynamic phenomena and derive design criteria
  • Delegates will be able to explain cost considerations limiting superconducting direct drive technology and identify potential optimization

Presenter's biography

Biographies are supplied directly by presenters at EWEA 2015 and are published here unedited

Asger B. Abrahamsen holds a master degree in Applied Physics (1999) and a PhD degree (2003) from the Technical University of Denmark (DTU). In 2012 he joined the Department of Wind Energy of DTU with focus on advanced materials such as superconductors and permanent magnets for wind turbine generators. He is working on utilizing SC wires in coils targeted for future 10-20 MW direct drive generators (INNWIND.EU). ABA is involved in the processing of NdFeB magnets in order to understand the relations between the rare earth elements in the magnets and the obtained magnetic properties (
