Title:
MAGNETIC BEARING AND COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2023/226418
Kind Code:
A1
Abstract:
A magnetic bearing and a compressor comprising same. The magnetic bearing comprises an axial control assembly (100) and a radial control assembly (200), wherein the axial control assembly (100) comprises an axial iron core (101) and an axial winding assembly (102) located in the axial iron core (101), and the axial winding assembly (102) is sleeved on an outer circumferential side of the radial control assembly (200). The technical solution reduces the occupied space along the length of a rotating shaft, such that the rotating shaft can be designed to have a shorter length, and can be correspondingly designed to have a higher limit rotation speed, and a winding can be wound easily, which thus can ensure the space factor of the winding. Therefore, the winding has a more compact structure and a smaller volume while the bearing has the same performance. Moreover, a winding lead of the axial winding assembly (102) located on an outer side can be led out more conveniently.
