Abstract

The invention relates to a magnetic suspension bearing stator, a magnetic suspension bearing and a compressor. The magnetic suspension bearing stator comprises: a stator iron core (4); a stator coil (5) wound on the stator iron core (4); a casing (2) ), sleeved outside the stator iron core (4), and clearance fit or transition fit with the stator iron core (4); and a potting component (3), filled in the casing (2) and the between the stator cores (4). By applying the technical solution of the present invention, the stator iron core and the casing have clearance fit or transition fit, which improves the problem of low machining precision existing in the related art of shrinking the stator iron core into the casing.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a magnetic suspension bearing stator, a magnetic suspension bearing and a compressor. Background technique [0002] Different from traditional rolling bearings and sliding bearings, magnetic suspension bearings use electromagnetic force or permanent magnetic force to suspend rotating parts in the air and maintain a non-contact state with other objects. They have excellent performances such as high precision, high speed, no lubrication, and low loss. . Such as figure 1 As shown, the stator assembly of a radial magnetic levitation assembly includes a radial stator core 2, a housing 1 for installing the radial stator core, and a coil 3 wound on the magnetic poles of the radial stator core. The stator core 2 and the housing 1 mostly adopt an interference fit to ensure their circumferential and axial positioning. Put the stator core 2 into the heated shell 1 to ensure the interf...
