Design Aspects on Winding of an MgB2 Superconducting Generator Coil
Magnusson, N.; Eliassen, J.C.; Abrahamsen, A.B.; Nysveen, A.; Bjerkli, Jarle; Runde, Magne; King, Patrick (Journal article; Peer reviewed, 2015) -
Hysteresis losses in MgB2 superconductors exposed to combinations of low AC and high DC magnetic fields and transport currents
Magnusson, Niklas; Abrahamsen, A.B.; Liu, D; Runde, Magne; Polinder, Henk (Peer reviewed; Journal article, 2014)MgB2 superconductors are considered for generator field coils for direct drive wind turbine generators. In such coils, the losses generated by AC magnetic fields may generate excessive local heating and add to the thermal ... -
Testing of an MgB2 coil for a wind turbine generator pole
Magnusson, Niklas; Hellesø, Svein Magne; Mikkonen, R.; Abrahamsen, A.B.; Runde, Magne; Berg, Gunnar; Nysveen, Arne (Peer reviewed; Journal article, 2021)We report on the testing of a 1 m long and 0.5 m wide racetrack coil wound from 4.5 km of MgB2 tape-shaped superconductors with a copper strip soldered to the nickel matrix. The cross-section of the coil corresponds to ...
