One-side hybrid axial magnetic bearing

The invention relates to a structure of a magnetic bearing, and in particular relates to a one-side hybrid axial magnetic bearing. The one-side hybrid axial magnetic bearing consists of a stator assembly and a rotor assembly; the stator assembly is formed by assembling an annular inner magnetic pole, an annular permanent magnet and an annular outer magnetic pole from the inside out in sequence, wherein a circular groove is formed in the annular outer magnetic pole, and a control winding is wound inside the circular groove; and the rotor assembly comprises a rotor circular disc and a rotating shaft, and the rotor circular disc is thermally sleeved on the rotating shaft. The one-side hybrid axial magnetic bearing has the advantages of being small in volume, light in weight, simple in structure, convenient to process, and the like, and can be suitable for occasions requiring high bearing capacity; and the one-side structure can be arranged at any end of the shaft as contactless support of a rotary mechanism with axial bearing capacity (such as gravity) in mechanical equipment such as electric motors and machine tools. The one-side hybrid axial magnetic bearing is particularly suitable for vertical structures or occasions requiring continuous bearing capacity axially, such as in flywheel energy storage structures or turbine mechanisms.
