Abstract
Electrical machines on the base of high temperature superconductors (HTS) could provide high specific (kW/kg) and volumetric (kW/m3) power. The most promising of them are fully HTS machines. Significant number of parameters and factors which have an impact on HTS windings make analytical analysis of the machine very complex. In this paper description of the prototype of fully HTS electrical machine is provided. Manufactured prototype was tested, experimental and calculation results were compared. In particular, open circuit performance is in good correlation with theoretical conclusions. Besides, results of experimental research of 15 HTS coils are provided. Some design features of the prototype are described.
