Magnetic pole structure of magnetic suspension electromagnet

The utility model belongs to the technical field of electromagnets, and discloses a magnetic pole structure of a magnetic suspension electromagnet, which comprises an iron core and a coil wound outside the iron core, the iron core and the coil are wrapped by a resin layer, and a sealing reinforcing structure is arranged on the contact surface of the resin layer and the iron core, so that the bonding reliability is improved, and the resin deformation is compensated; according to the sealing reinforcing structure, a first groove-shaped structure and/or a protruding structure are/is arranged around the surface of the iron core so that the contact area of resin and the iron core can be increased, and the bonding reliability can be 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 impro
