Abstract: High magnetic field can be trapped in a bulk type-II superconductor through different magnetization methods. In our fully high-temperature superconducting (HTS) synchronous motor, the pulsed field magnetization (PFM) method is adopted due to its reduced cost, feasibility, and adaptability on the assembling of our HTS motor system. The HTS rotor was designed with 75 YBCO HTS bulks mounted on the surface of the rotor to make two pairs of poles after the PFM. In this paper, we give a PFM circuit used to generate a pulsed magnetic field about 1.5 T at the center of the magnetizing coil lasting less than 1 s by discharging a capacitor bank. We also investigate the homogeneity of the pulsed magnetic field produced by the coils. The main strategy for magnetizing the superconducting rotor is designed and investigated, and the rotor field profile after the whole magnetization procedure is measured and discussed as well.
