Abstract
Background: analysis of the influence of cooling conditions of high-temperature superconducting elements on the power characteristics of a maglev system under conditions of rapidly changing magnetic fields
 Aim: analysis of the influence of cooling conditions of high-temperature superconducting elements on the force characteristics of a magnetic-levitation transport platform under conditions of rapidly changing magnetic fields caused by the inhomogeneity of the magnetic track.
 Methods: numerical analysis of the maglev system was performed by the finite element method in the Comsol Multiphysics engineering simulation software.
 Results: at fast, more than 5 T/s, magnetic field change rates, due to the motion of the superconductor in a magnetic field with a non-uniform local distribution, the preferred method of cooling is the use of cryocooler technology. At rates of change of the magnetic field less than 5 T/s, it is permissible to use liquid nitrogen as a cooler.
 Conclusion: The developed numerical model makes it possible to predict the dynamic characteristics of levitation systems of various scales and can be applied to contactless transport, as well as in rotating machines, including kinetic energy storage devices.
