The purpose of this study is to establish a pulse magnetization technique to ensure high performance of superconducting bulk motors for ship propulsion in actual operation. Pulse magnetization using vortex-type copper coils was attempted at liquid nitrogen temperature on an array consisting of three GdBCO bulks that imitate field poles. When the three coils placed opposite each other in the bulk were connected in series, a flux density distribution similar to that obtained by magnetization in a static magnetic field was obtained. When pulsed magnetic fields were applied to the three bulks in sequence, a reduction of up to 12% of the trapped flux density was observed in the center of the adjacent bulk due to interference from each other's pulsed magnetic field. However, by devising the conditions for sequential magnetization, it was possible to improve the magnetic flux density distribution compared to magnetization using coils connected in series.
