A versatile testing platform for a High
Temperature Superconductor (HTS) machine has been
constructed. The stationary HTS field winding can carry up to 10
coils and it is operated at a temperature of 77K. The rotating
armature is at room temperature.
Test results and performance for the HTS field winding
comprising four coils wound with two types of HTS tapes are
shown and discussed. The field winding produces up to 0.62T in
the 10mm air gap which constitutes 78% of the armature design
value. Recommendations for the field winding operation are
proposed and verified, which resulted in an increase of available
magneto-motive force of the field winding up to 25%.
