“…permanent magnets (PMs) and HTSCs. To describe the wide range of possible applications of HTSCs, different calculation methods/models of the HTSC‐PM interaction have to be developed (Tsuchimoto et al , 1993, 1994a, b). They have to be applicable for the design and optimisation of such HTSC systems (Lee, 2001; Sheanen, 1994).…”

To describe the wide range of possible applications of high temperature superconductors (HTSCs) (e.g. magnetic bearings, levitation systems or electrical machines) several appropriate calculation algorithms have been developed. They determine the force interaction between a superconductor and any even multidimensional magnetic field excitation system. Especially good agreements between experiments and computed results have been obtained for the Vector‐Controlled Model, which seems to be the best approximation of the macroscopic superconductivity behaviour. The validation of this model by means of measurements makes it a powerful tool for the design and optimisation of any HTSC application in the field of force generation. It can be used not only for the designing of levitation applications, but also to help the understanding of the flux penetration, flux trapping and magnetisation of bulk superconductors in non‐uniform magnetic fields. By means of this model, the force interaction between superconductors and external magnetic fields for practical multi‐polar configurations, e.g. superconducting levitation systems or inherently stable superconducting bearings has been determined. Furthermore, the time dependency of the forces taking flux flow and flux creep into account, can be considered.

“…Creating an accurate physics-based model of this interaction between these vortices and the original magnetic field represents a dauntingly complex task. Several groups have worked on creating models based on approximations or around specific setups [15][16][17][18][19]. Kordyuk proposed a particularly general model of the flux-pinning effect termed the frozen image model.…”

“…There are many approaches to finding force and torque expressions that have been presented in recent literature [13][14][15][16][17][18]. Approaching the force and torque interaction from an analytical point of view is often complicated by a lack of a convenient manner in which to express the currents and their derivatives induced in the HTSC surface.…”
