The invention discloses a hybrid braking excitation structure for a maglev train. Magnetic poles formed by electromagnets and permanent magnets are arranged along the rail direction and are installed on the bottom of the maglev train right over rails. Each magnetic pole comprises a core, an armature coil, and a permanent magnet. The cores are arranged at intervals along the rail direction. The horizontal periphery of each core is wrapped in the armature coil provided with exciting current. The top of each core is equipped with the corresponding permanent magnet such that the magnetic poles are formed. The top of the permanent magnets are equipped with a magnet yoke along the rail direction. The bottoms of the cores are equipped with a wearing plate. By means of the adjustment of exciting current in an exciting coil, a dynamic maglev train braking process is achieved. By means of reverse excitation, a braking system is simply repositioned. The magnetic force of the permanent magnets enhances eddy current braking control and friction braking effects. The hybrid braking excitation structure reduces the heating of the system, achieves an energy-saving effect and heat management of the system, and is provided with a braking operation mode with safe fault guidance.
