Title:
MAGNETIC BEARING, COMPRESSOR AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/226405
Kind Code:
A1
Abstract:
A magnetic bearing, a compressor and an air conditioner. The magnetic bearing comprises: an axial iron core (5), permanent magnets (2), a magnetic conductive ring (7) and a magnetic steel fixing frame (12); the permanent magnets (2) comprise a first permanent magnet (21) located on one axial side of the magnetic conductive ring (7) and a second permanent magnet (22) located on the other axial side of the magnetic conductive ring (7); the first permanent magnet (21) is located between the magnetic conductive ring (7) and the axial iron core (5) and is respectively connected to the magnetic conductive ring (7) and the axial iron core (5); the second permanent magnet (22) is located between the magnetic conductive ring (7) and the axial iron core (5) and is respectively connected to the magnetic conductive ring (7) and the axial iron core (5). The magnetic steel fixing frame (12) can fix and support the radial inner sides of the permanent magnets (2). According to the magnetic bearing, the compressor and the air conditioner, the bias magnetic fields on the two axial sides are more uniform, and the supporting, fixing and positioning effects on the partitioned permanent magnets are improved, so that the bias magnetic fields are further made more stable, the distribution of the bias magnetic fields is more uniform, and the output load of the axial magnetic bearing is stable.
