“…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].…”

This paper presents a numerical modeling method for AC losses in highly dynamic linear actuators with high temperature superconducting (HTS) tapes. The AC losses and generated force of two actuators, with different placement of the cryostats, are compared. In these actuators, the main loss component in the superconducting tapes are hysteresis losses, which result from both the non-sinusoidal phase currents and move ment of the permanent magnets. The modeling method, based on the H-formulation of the magnetic fields, takes into account permanent magnetization and movement of per manent magnets. Calculated losses as function of the peak phase current of both super conducting actuators are compared to those of an equivalent non-cryogenic actuator.
