Abstract One of the most promising applications for high temperature superconducting (HTS) material is magnet manufacturing. HTS magnets are considered to be used in wide range of applications such as MRIs, particle accelerators, as well as electrical machines. HTS rotating machines are mainly utilized for cryo-electrification, i.e. application of superconductivity for modern electrification. One of the main aspects of cryo-electrification is electric aircraft application which is recently enabled by continuous progress in design development of superconducting magnets and HTS machines. This paper discusses the challenges in front of application of a newly developed magnet type, i.e. HTS ring magnets for being used in superconducting rotating machine in future electric aircrafts. HTS ring magnet is compact, easy to develop, fault tolerant, and light weight which recently reached to a high level of magnetic field.
