Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. The following description of at least one exemplary embodiment is merely illustrative in nature and in no way taken as limiting the invention, its application or uses. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] Such as Figure 1 to Figure 3 As shown, the first embodiment of the present invention provides a stator, including: a yoke 10, the yoke 10 is an annular structure, and the inner wall of the yoke 10 is provided with assembly grooves 11 at intervals along the circumferential direction; th...

Abstract

The invention provides a stator, a magnetic suspension bearing and a motor. The stator comprises: a yoke portion, wherein the yoke portion is of an annular structure, and assembly grooves are formed in an inner wall of the yoke portion along the circumferential direction at intervals; a tooth portion, wherein the tooth portion is used for setting a winding, one end of the tooth portion is an assembly end, and the assembly end is cooperatively connected with the assembly grooves; and a limiting structure used for preventing the tooth portion from moving relative to the axial direction of the yoke portion. In this way, the tooth portion and the yoke portion become separated structures, during the production, the winding is twined on the tooth portion at first, and then the assembly end of the tooth portion is cooperatively connected with the assembly grooves, therefore no interference is generated when the winding is twined, automatic twining can be conveniently achieved, and thus the winding can be conveniently twined. Furthermore, by setting the limiting structure, the relative motion of the yoke portion and the tooth portion on the axial direction can be avoided, and the structural strength and reliability of the stator are improved.

Description

technical field [0001] The invention relates to the technical field of stator cores, in particular to a stator, a magnetic suspension bearing and a motor. Background technique [0002] In the prior art, the stator in the magnetic suspension bearing or the motor is composed of a whole piece of silicon steel sheet and a stator baffle. The stamped silicon steel sheets are stacked to form the main body of the stator, and the stator baffles on both ends are welded together with the silicon steel sheets. While playing a protective role, an axial force is exerted on the end faces of the silicon steel sheets to play a clamping role. . For this kind of stator core, due to the integral structure of the stator body and the obstructive effect of the stator baffle, the winding cannot be automated, and the winding coils need to be wound manually, which is not only inefficient but also has a high error rate; at the end of winding Finally, if it is found that the winding is wrong, it is n...
