25 kW demonstrator and scale model designed and constructed in 1994 and became the basic for the later activities.
Prior to that Professor Ulrik Krabbe designed the first permanent magnet generator at DTU in 1980. Dr. Krabbe contributed also to this design.
The generator was tested by Risø National Laboratorium now DTU. See the test paper published at an AWEA conference:
Direct drive generators have been manufactured in more
than 100 years. This generator at Tange hydro
power station is from 1921 manufactured by Thrige in Odense.
