The invention provides a variable Halbach array permanent magnet hybrid electromagnetic suspension system. The variable Halbach array permanent magnet hybrid electromagnetic suspension system comprises a guide rail, an inner-pole Halbach array permanent magnet, a suspension coil, an inner electromagnetic iron core, a fastening screw, a right-angle connecting plate, a movable permanent magnet, an outer electromagnetic iron core and an outer-pole Halbach array permanent magnet, the guide rail is made of a soft magnetic material and has an F-shaped structure; the inner electromagnetic iron core and the outer electromagnetic iron core are made of soft magnetic silicon steel sheet materials, are jointly combined with the movable permanent magnet to form a U-shaped structure iron core, and are fixedly connected through the right-angle connecting plate and the fastening screw; the movable permanent magnet is positioned in the middle of the U-shaped structure iron core and can be driven to move up and down; the suspension coil is wound on the inner electromagnetic iron core or the outer electromagnetic iron core; the inner-pole Halbach array permanent magnet and the outer-pole Halbach array permanent magnet are arranged at the two ends of the inner electromagnetic iron core and the two ends of the outer electromagnetic iron core correspondingly and correspond to guide rail magnetic poles. The electromagnetic suspension system has the characteristics of low power consumption, large suspension air gap, safety and reliability, and can be used as the electromagnetic suspension system for a maglev train.
