Abstract
- High temperature superconducting (HTS) stacks of superconducting tapes provide a solution for all-superconducting electrical machines since they could work as trapped-field magnets. Most experiments with these stacks use pieces of tapes with relatively small areas as wider tapes are more difficult to acquire, therefore in this paper we investigate substitutions for these wider tapes to be implemented in superconducting electrical machines. With different stack architectures and substrate materials made by different manufacturers with different widths, the magnetizing effect using pulse field magnetization (PFM) would be different. To explore the differences of this effect, different stacks are tested in a modified synchronous machine designed by ASuMED under liquid nitrogen conditions. By changing the stacks of the tape and testing them under the same condition, the characteristics of the trapped flux, magnetization and demagnetization are affected, the difference is then compared to a COMSOL finite element model using an electromagnetic-thermal coupled model to investigate this effect. This paper shows the experimental setup for a PFM for HTS stacked coated conductor (CC) within an electrical machine, different stack architectures are tested and simulated, and the magnetic characteristics are compared and discussed, where the simulation and experiment agree in a certain degree, and the sectioned HTS CC stacks can proven to be useful in an electrical machine.
