Abstract: One potential advantage of the application of superconducting materials in electrical machines is the possibility to build lighter and compact devices by removing iron. These machines find applications, e.g., in systems where cryogenics is already available, or in naturally cryogenic environments. The design of motors with high temperature superconductors (HTS) presents issues unconsidered in classical machines, besides considerations on cryogenics, such as HTS brittleness or mechanical restrictions. Moreover,… Show more

“…This is particularly relevant in ironless devices, as magnetic flux lines are spread in surrounding medium. In a previous work, the force developed by an all superconducting linear motor was derived by averaging magnetic flux density of two trapped flux magnets over the volume of superconducting coils in the armature of the motor [4]. This flux density was calculated by means of sand pile model [5], where persistent currents are assumed to flow in concentric loops parallel to sample edges.…”

“…A linear actuator with a copper stator winding and field-cooled HTS bulk material in the translator was developed for electromagnetic aircraft launch systems [2], where the translator is levitated using HTS bulk levitation components. Another electromagnetic aircraft launch system, with superconducting stator coils and a field-cooled bulk HTS mover, was presented in [3,4]. The use of trapped field HTS bulks is less suitable for the application described in this paper, since the trapped field attenuates as a result of an applied AC magnetic field [5].…”
