Calculation, Design, and Winding Preliminary Tests of 90-kW HTS Machine for Small-Scale Demonstrator of Generating System for Future Aircraft With Hybrid Propulsion System

Achieving high values of specific power for electric machines needs application of high temperature superconductors (HTS). Production of HTS machines requires development of calculation methods, technology and experimental verification of applied methods. This article represents the results of calculation and modeling of a 90-kW 6000-r/min synchronous machine with HTS armature winding. The considered machine consists of permanent magnet rotor and three-phase stator HTS winding which contains nine double pancake racetrack coils. All coils have been produced and critical current for each coil and n-value were obtained. Machine design was developed. Obtained results allow us to finally assemble the machine and provide experimental research.
