Description
The development of high-temperature superconducting (HTS) electrical machines results in applications of various fields, as they have higher efficiency and power density. Axial field machine (AFM) is a machine topology with higher efficiency and power density, and is a novel way to achieve fully-superconducting electrical machine for various applications. Stacked HTS coated-conductors (CC) have been proven to be a feasible way as trapped field magnets on machine rotors, due to their ability to trap high magnetic fields. Modelling of AFM is more complicated than conventional radial field machines, as they have inconsistent structure axially and radially. This paper presents a design of AFM with stacked HTS CC, with its own magnetization circuit layout within the machine topology, this design is simulated with COMSOL Multiphysics with 2D and 3D simulation using H-A and T-A formulation, where the superconducting coil is simulated with a 2D infinitely long model, this model also divides the electrical machine into two parts: the superconducting parts and non-superconducting parts. This design will use both simulated results and experiment data to optimize the overall design,
