Preferably, the axial displacement sensor 4 in this embodiment is arranged at the non-output end of the rotor shaft 2 and is located on an axial extension of the rotor shaft 2. The axial displacement sensor 4 is arranged at the non-output end of the rotor shaft 2, so that the structure of the magnetic levitation motor is more compact.
Preferably, in this embodiment, two axial magnetic bearings 3 are provided, the two axial magnetic bearings 3 are respectively disposed at two sides of the motor stator core 1, and two ends of the rotor shaft 2 are respectively provided with step surfaces matched with magnetizers at two sides of the axial magnetic bearings 3, so that, for facilitating the rotor shaft 2 to pass through the axial magnetic bearings 3 to be assembled, the inner diameter of the magnetizer at one side of the axial magnetic bearings 3 close to the motor stator core 1 is larger than the inner diameter of the magnetizer at one side far away from the motor stator core 1. The two ends of the rotor shaft 2 are respectively provided with an axial magnetic bearing 3, the rotor shaft 2 passes through the axial magnetic bearings 3 during assembly, so that two magnetizers of the axial magnetic bearings 3 are respectively contacted with two step surfaces on the rotor shaft 2, and the installation of the axial magnetic bearings 3 can be completed, and the assembly is simple and convenient. The two axial magnetic bearings 3 respectively realize the supporting limit of the left end and the right end of the rotor shaft 2, and the control of the axial magnetic bearings 3 is simpler. The arrangement of the axial magnetic bearing 3 in this embodiment is not limited to this, and a thrust disk may be provided on the rotor shaft 2, and one axial magnetic bearing 3 may be provided to cooperate with the thrust disk, and both sides of the thrust disk are respectively used as bearing surfaces for the axial magnetic bearing 3 to support the rotor shaft 2, so that the axial magnetic bearing 3 needs to be mounted in blocks during mounting, and the assembly is complex.
Preferably, the magnetic levitation motor further comprises a housing, wherein the motor stator core 1, the radial stator permanent magnet 6 and the axial magnetic bearing 3 are all fixed in the housing, and the output end of the rotor shaft 2 extends out from one side of the housing. Specifically, in this embodiment, the casing includes two sub-casings 7 with one open end, the open ends of the two sub-casings 7 are detachably connected, a radial stator permanent magnet 6 and an axial magnetic bearing 3 are respectively fixed in each sub-casing 7, and a shaft hole for extending the rotor shaft 2 is formed in the end of the sub-casing 7 opposite to the open end.

Since the rotor shaft 2 at the corresponding position of the axial magnetic bearing 3 is provided with the step to cause the diameter to be smaller, if the axial magnetic bearing 3 is arranged at the position relatively close to the motor stator core 1, the shaft diameter of the rotor shaft 2 can be changed too much to influence the strength and the service life of the rotor shaft 2, and since the repulsive force between the radial rotor permanent magnet 5 and the radial stator permanent magnet 6 of the permanent magnet group is related to the area, if the axial magnetic bearing 3 is arranged at the position relatively close to the motor stator core 1, the permanent magnet group is arranged at the position relatively far away from the motor stator core 1, and under the condition of providing the same repulsive force, the width of the permanent magnet group which needs to be arranged due to the small diameter of the rotor shaft 2 can be increased. Therefore, in the embodiment of the invention, the radial stator permanent magnet 6 is positioned between the axial magnetic bearing 3 and the motor stator core 1, so that the service performance of the motor is ensured, and meanwhile, the space is further saved, and the structure is more compact. Meanwhile, as the radial rotor permanent magnet 5 is required to be fixed on the rotor shaft 2 during assembly, the diameter of the radial rotor permanent magnet is larger, and the radial stator permanent magnet 6 is arranged between the axial magnetic bearing 3 and the motor stator core 1, so that the assembly is convenient.
