Abstract
Features of energy conversion in the linear electromechanical vibration device with an element made of high-temperature superconducting (HTS) material are considered. A disk-shaped permanent magnet with axial magnetization moves inside a fixed circular coil, and a ceramic HTS element, also disk-shaped, is fixed at a distance from the permanent magnet. All converter elements are arranged coaxially. The HTS element transitions into a superconducting state in the magnetic field of the permanent magnet. The purpose of the investigation is to find the effect of the HTS element effect on the static and dynamic parameters of the converter by comparing the operation of the device with the HTS element and without it. Mathematical models are developed for the calculation of dynamic characteristics of the device in the Matlab/Simulink software environment for electrical and mechanical subsystems. The connection between the subsystems is defined by functions of flux linkage of the coil and the electromagnetic force, which are obtained by the analysis of the electromagnetic field by the method of spatial integral equations taking into account HTS material properties. A combined model of HTS material properties is proposed with two sources of magnetic fields (magnetization and current density), which is more universal than current only models.
