Axial magnetic bearing stator

The invention relates to a magnetic suspension bearing system, in particular to an axial magnetic bearing stator, which comprises an outer stator assembly, an inner stator assembly and an inner stator assembly, the outer stator assembly comprises a coil and an open-circuit magnetic conductive shell coated outside the coil, and the inner diameter of the outer stator assembly is larger than the diameter of a thrust disc on a rotor; the inner stator assembly is composed of a split magnetic conductive base and a split magnetic conductive circular ring, and the inner stator assembly can be divided into at least two parts along the plane passing through the rotating shaft; and the combined magnetic conductive base and the combined magnetic conductive circular ring are respectively connected and combined with the open-circuit magnetic conductive shell of the outer stator assembly along the outer circumferential surface to form an open-circuit magnetic conductive shell of the axial magnetic bearing stator.
