Axial magnetic suspension bearing and magnetic suspension rotating machine

The invention provides an axial magnetic suspension bearing and a magnetic suspension rotating machine, the axial magnetic suspension bearing comprises an outer cylinder, two axial stator assemblies and a thrust disc are assembled in a central through hole of the outer cylinder, each axial stator assembly comprises a stator iron core and a winding, the thrust disc is located between magnetic poles of the two stator iron cores, and the winding is arranged between the two stator iron cores. The magnetic poles of the stator core comprise an outer magnetic pole and an inner magnetic pole, a rotating groove is formed in the surface area, opposite to the outer magnetic pole, of the thrust disc, the rotating groove extends towards the outer side from the radial inner side of the thrust disc, winding cooling flow channels are formed in the two axial stator assemblies, and the winding cooling flow channels are used for cooling windings at the corresponding positions. And the winding cooling flow channels of the two ax
