Abstract: In relevant maglev vehicle systems, a permanent magnetic guideway (PMG) serves as a stable source of magnetic field. High-quality PMG regularity is crucial in attaining a homogeneous magnetic field, as any inhomogeneous magnetic field can aggravate vehicle vibration. Furthermore, deviations in the PMs caused by installation errors and interaction forces can degrade PMG regularity. This issue is frequently encountered in Halbach-type PMG. This study aimed to elucidate the formation mechanism of PMs with vertical deviation. The effects of initial PMG irregularity on the magnetic field were investigated, revealing a significant reduction in the vertical and horizontal magnetic fluxes. A novel mortise-tenon structure is proposed to join the PMs' seams and improve the initial PMG irregularity. The optimal structure was selected and evaluated. Finally, the structural design of tenon parameters on the levitation performance was discussed, indicating that PM consumption plays a more significant role than the tenon structural parameters.
