The invention belongs to the technical field of electromagnets, and discloses an anti-cracking method for magnetic poles of a magnetic levitation electromagnet, the magnetic levitation electromagnet comprises an iron core and a coil wound outside the iron core, and the iron core and the coil are wrapped by a resin layer; a sealing reinforcing structure is arranged on the contact face of the resin layer and the iron core, resin deformation is compensated, and bonding reliability is improved. The sealing reinforcing structure comprises a first groove-shaped structure arranged on the winding surface of the iron core, the contact area of resin and the iron core is increased, and the bonding reliability is improved. The resin layer comprises an exposed face and a binding face, and a second groove-shaped structure is arranged on one side of the exposed face. The resin-iron core contact surface structure is optimally designed, so that the insulation reliability of the magnetic pole is improved, and the overall service life is prolonged.

    本发明属于电磁铁技术领域,公开一种磁悬浮电磁铁磁极的抗开裂方法,所述磁悬浮电磁铁包括铁芯、绕制在铁芯外的线圈,铁芯和线圈外包裹有树脂层;在树脂层与铁芯接触面设置密封补强结构,补偿树脂变形量,提高粘接可靠性。密封补强结构包括在铁芯上绕表面设置第一槽型结构,增大树脂与铁芯接触面积,提高粘接可靠性。树脂层包括露置面和贴合面,所述露置面一侧设置有第二槽型结构。通过对树脂-铁芯接触面结构进行优化设计,提升磁极绝缘可靠性及整体寿命。
