The invention discloses a magnetism-increasing decoupling axial-flux switching dual-rotor motor. A rotor of the motor adopts a disc-type salient pole structure, and a stator is embedded between a first rotor and a second rotor, is of a salient pole structure and comprises a stator core, a tangential permanent magnet, a magnetism-increasing permanent magnet, a radial permanent magnet and an armature winding. In the magnetism-increasing decoupling axial-flux switching dual-rotor motor, the magnetism-increasing permanent magnet is additionally arranged on the central surface of the stator core of the motor, the whole magnetic path of the motor is divided into a left part and a right part, the magnetism-increasing permanent magnet plays a role in suppressing coupling of the left rotor magnetic path and the right rotor magnetic path, the coupling of the left rotor magnetic path and the right rotor magnetic path can be reduced to a certain extent, and thus, the left rotor and the right rotor have abilities of independent running. Meanwhile, a magnetism gathering effect is generated among the magnetism-increasing permanent magnet, the tangential permanent magnet and the radial permanent magnet, the gap flux density of the motor is further increased, and the power density of the motor is improved. No winding and no permanent magnet are arranged on the rotors, the magnetism-increasing decoupling axial-flux switching dual-rotor motor has the characteristics of simplicity in structure, low cost and small rotational inertia, is applicable for running at a high speed, and can be rapidly started, and a few iron core materials are required for the disc-type structured rotor.
