Title:
MAGNETIC BEARING STATOR, MAGNETIC BEARING, AND COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2022/068198
Kind Code:
A1
Abstract:
A magnetic bearing stator, a magnetic bearing, and a compressor. The magnetic bearing stator comprises: a stator core (4); a stator coil (5) wound around the stator core (4); a housing (2), which is sleeved outside the stator core (4) and is in clearance fit or transition fit with the stator core (4); and a potting component (3), which fills the space between the housing (2) and the stator core (4). The stator core is in clearance fit or transition fit with the housing, such that the problem of low machining precision caused by shrink-fitting the stator core in the housing is alleviated.
