摘要: High-temperature superconductors have created the opportunity for a step change in technology of power applications. Racetrack superconducting coils made from YBCO coated conductors been used several engineering applications including SMES, rotor or stator windings electric machines. AC loss is one most important factors that determine design and performance devices. In this paper, numerical model developed to calculate losses racetrack different magnetic conditions. This paper first discusses self-field external field only. It then goes investigate being exposed ripple DC background field. Finally, carrying current are calculated. These two scenarios correspond using as winding an machine.
