MAGNETIC BEARING AND COMPRESSOR

WIPO Patent Application WO/2023/226401

A1

Disclosed are a magnetic bearing and a compressor. The magnetic bearing comprises a first axial iron core (101) and a radial iron core (201), wherein the first axial iron core (101) has a first accommodating space, in which an annular positioning boss (102) is provided; the annular positioning boss (102) has an axial positioning surface and a radial positioning surface; and a magnetic conductive ring (103) is provided in the first accommodating space, the magnetic conductive ring (103) can be connected to both the axial positioning surface and the radial positioning surface in a fitting manner to achieve positioning of the magnetic conductive ring (103) in both an axial direction and a radial direction of the first axial iron core (101), and the magnetic conductive ring (103) is sleeved on an outer circumferential wall of the radial iron core (201). In the magnetic bearing and the compressor, the positioning of the radial iron core is more accurate, so as to effectively avoid the problem of great positioning accuracy error of a radial iron core in the prior art due to association of the positioning with magnetic steel.
