Bulk high temperature superconductors are usually used as arrays due to the limited size and performance of a single bulk. To find a reasonable array pattern for the superconducting maglev vehicle, we studied the levitation force of four multi-seeded rectangular YBaCuO blocks with three possible arrays above a permanent magnet guideway (PMG). Experimental results show that the levitation force can be improved through an optimal array pattern of the bulk superconductor. The method is to avoid the joint gaps of bulk arrays in a strong magnetic field area of the PMG thus improving the utilization rate of the applied magnetic field. The optimal array pattern will be helpful to improve the levitation performance and reduce the quantity of onboard superconductors.
