Superconducting linear actuators for highly dynamic motion

By BJH Bart de Bruyn, JW Helm Jansen and E Elena Lomonova

Abstract

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