Problems solved by technology

[0006] For the above two structures, if the traditional structure is adopted, it needs to be used together with insulating slot paper, and the slot paper will move during the winding process, which has a large safety hazard; Structures such as wire clips make the axial dimension of the stator assembly exceed the required range, and it will also lead to problems such as insufficient strength of the wire clips and confusing wiring, which makes the structure and wiring of each skeleton more complicated and difficult. Guarantee the quality of stator components
If a separate structure is used, the assembly is more cumbersome, making the efficiency very low

Abstract

The invention relates to a magnetic bearing stator component and a preparation method thereof. The stator component comprises a stator iron core (2), coils (3) and two stator iron core frameworks (1), wherein the two stator iron core frameworks (1) are respectively buckled to two axial end parts of the stator iron core (2), wherein one buckled end of one stator iron core framework (1) is provided with a hollow part (18), and the buckled end of the other stator iron core framework (1) is provided with a projection part (19); the hollow part (18) and the projection part (19) are buckled with each other; each coil (3) winds the corresponding tooth (22) of the stator iron core (2). The stator component is easy to assemble; after installation, the two stator iron core frameworks can be fit completely, the assembling is firm, and the insulation reliability can be ensured; moreover, the completely same structure can be adopted for the two stator iron core frameworks, the part universality is relatively high, and parts can be changed mutually in the assembling process; meanwhile, the mold opening expense also can be reduced, and the standardization can be realized easily.

Description

technical field [0001] The invention relates to the technical field of magnetic suspension bearings and motors, in particular to a magnetic suspension bearing stator assembly and a manufacturing method. Background technique [0002] Magnetic suspension bearings use magnetic force to suspend the rotor in the air, so that there is no mechanical contact between the rotor and the stator. Compared with traditional ball bearings and sliding bearings, magnetic suspension bearings have no mechanical contact, the rotor can run to a high speed, and has the advantages of low mechanical wear, low noise, long life, and no lubrication. Therefore, magnetic suspension bearings are used in motors. has been widely applied. [0003] The magnetic suspension bearing is similar to the motor structure. It mainly uses the electromagnet installed on the machine base to induce a magnetic field in the rotating rotor, and the rotor is suspended through the interaction of the stator and rotor magnetic ...
